Copper core Cross-sectional view of a coaxial cable Coaxial cable, or coax (pronounced ) is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable was invented by English physicist, engineer, and mathematician Oliver Heaviside, who patented the design in 1880.

A type N coaxial RF connector (male) Electronic symbols for the plug and jack coaxial connectors Time-domain reflectometry shows reflections due to impedance variations in mated RF connectors. A coaxial RF connector (radio frequency connector) is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers. Better models also minimize the change in transmission line impedance at the connection in order to reduce signal reflection and power loss.

Hybrid fiber-coaxial (HFC) is a telecommunications industry term for a broadband network that combines optical fiber and coaxial cable. It has been commonly employed globally by cable television operators since the early 1990s. In a hybrid fiber-coaxial cable system, the television channels are sent from the cable system's distribution facility, the headend, to local communities through optical fiber subscriber lines. At the local community, a box called an optical node translates the signal from a light beam to radio frequency (RF), and sends it over coaxial cable lines for distribution to subscriber residences.
|
|
Coaxial cables are capable of bi-directional carriage of signals as well as the transmission of large amounts of data. Cable television signals use only a portion of the bandwidth available over coaxial lines. This leaves plenty of space available for other digital services such as cable internet, cable telephony and wireless services, using both unlicensed and licensed spectrum. Broadband internet access is achieved over coaxial cable by using cable modems to convert the network data into a type of digital signal that can be transferred over coaxial cable.

Later, some manufacturers of LAN equipment, such as Datapoint for ARCNET, adopted RG-62 as their coaxial cable standard. The cable has the lowest capacitance per unit-length when compared to other coaxial cables of similar size. All of the components of a coaxial system should have the same impedance to avoid internal reflections at connections between components (see Impedance matching). Such reflections may cause signal attenuation.

A coaxial cable-only system is typically referred to as a passive system when all system components (other than the signal source) are coaxial cable, coverage antennas and other components that do not require AC or DC power to function.
|
|
The ends of coaxial cables usually terminate with connectors. Coaxial connectors are designed to maintain a coaxial form across the connection and have the same impedance as the attached cable. Connectors are usually plated with high-conductivity metals such as silver or tarnish- resistant gold. Due to the skin effect, the RF signal is only carried by the plating at higher frequencies and does not penetrate to the connector body.

The coaxial portion of the network connects 25–2000 homes (500 is typical) in a tree-and-branch configuration off of the node. RF amplifiers are used at intervals to overcome cable attenuation and passive losses of the electrical signals caused by splitting or "tapping" the coaxial cable. Trunk coaxial cables are connected to the optical node and form a coaxial backbone to which smaller distribution cables connect. Trunk cables also carry AC power which is added to the cable line at usually either 60 or 90 V by a power supply (with a lead acid backup battery inside) and a power inserter.

Kamov Ka-50 of the Russian Air Force, with coaxial rotors Coaxial rotors are a pair of rotors mounted one above the other on the same shaft and turning in opposite directions. The advantage of the coaxial rotor is that, in forward flight, the lift provided by the advancing halves of each rotor compensates for the retreating half of the other, eliminating one of the key effects of dissymmetry of lift: retreating blade stall. However, other design considerations plague coaxial rotors. There is an increased mechanical complexity of the rotor system because it requires linkages and swashplates for two rotor systems.

Coaxial cable is used as a transmission line for radio frequency signals. Its applications include feedlines connecting radio transmitters and receivers to their antennas, computer network (e.g., Ethernet) connections, digital audio (S/PDIF), and distribution of cable television signals. One advantage of coaxial over other types of radio transmission line is that in an ideal coaxial cable the electromagnetic field carrying the signal exists only in the space between the inner and outer conductors.

A coaxial cable has a central conductor surrounded by a sheath of conductor with insulation in between. Coaxial cables form a transmission line and confine the electromagnetic wave inside the cable between the center conductor and the shield. The transmission of energy in the line occurs totally through the dielectric inside the cable between the conductors. Coaxial lines can therefore be bent and twisted (subject to limits) without negative effects, and they can be strapped to conductive supports without inducing unwanted currents in them.

HKCTV is operated through two separate yet complementary networks, namely the wireless Multipoint Microwave Distribution System coaxial network (MMDS) and the wireline Hybrid Fibre coaxial network (HFC). The combined networks serve 1.70 million viewers, which take up 95% of the local households. MMDS is a programming broadcast through specific transmitters throughout Hong Kong. Broadcast signals are released from the transmitters to various "dishes" which are located on the rooftops of buildings, and are further transmitted to customers' televisions through the in-built coaxial cable.

Open wire test leads (flying leads) are likely to pick up interference, so they are not suitable for low level signals. Furthermore, the leads have a high inductance, so they are not suitable for high frequencies. Using a shielded cable (i.e., coaxial cable) is better for low level signals. Coaxial cable also has lower inductance, but it has higher capacitance: a typical 50 ohm cable has about 90 pF per meter. Consequently, a one-meter direct (1X) coaxial probe loads a circuit with a capacitance of about 110 pF and a resistance of 1 megohm.

The electrical coaxial cable (with RCA jacks) or optical fibre (TOSLINK). Note that there are no differences in the signals transmitted over optical or coaxial S/PDIF connectors—both carry exactly the same information. Selection of one over the other rests mainly on the availability of appropriate connectors on the chosen equipment and the preference and convenience of the user. Connections longer than 6 meters or so, or those requiring tight bends, should use coaxial cable, since the high light signal attenuation of TOSLINK cables limits its effective range.

A coaxial mount is mounted beside or above the primary weapon and thus points in the same general direction as the main armament, relying on the host weapon's ability to traverse in order to change arc. The term coaxial is something of a misnomer as the arrangement is strictly speaking paraxial (i.e., parallel axes, as opposed to the same axis), though for ballistic purposes the axis is effectively the same in practical terms. Nearly all main battle tanks and most infantry fighting vehicles have a coaxial machine gun mounted to fire along a parallel axis to the main gun.

The first Ethernet standard, known as 10BASE5 (ThickNet) in the family of IEEE 802.3, specified baseband operation over 50 ohm coaxial cable, which remained the principal medium into the 1980s, when 10BASE2 (ThinNet) coax replaced it in deployments in the 1980s; both being replaced in the 1990s when thinner, cheaper twisted pair cabling came to dominate the market. The use of coaxial cable for Ethernet has been deprecated by 2011. Research in Ethernet transmission over coaxial cable continued, as both consumers and telecommunications operators strive to use existing 75 ohm coaxial cable installations (from cable television or CATV), to carry broadband data into and through the home, and into multiple dwelling unit (MDU) installations. Most EoC technologies are being developed for in home or on premises networking and are expected to be operated within the domain of a single operator.

"Higher gain" in this case means that the antenna radiates less energy at higher and lower elevation angles and more in the horizontal directions. High-gain omnidirectional antennas are generally realized using collinear dipole arrays. These consist of multiple half-wave dipoles mounted collinearly (in a line), fed in phase. The coaxial collinear (COCO) antenna uses transposed coaxial sections to produce in-phase half-wavelength radiators.

Inductive coupling loops are typically used to couple magnetic flux into and out of the LGR. The coupling loops are made by first removing a length of outer conductor and dielectric from a semi-rigid coaxial cable. The exposed centre conductor is then bent into a loop and short-circuited to the outer conductor. The opposite end of the coaxial cable is connected to either a signal generator or a receiver.

Thus the kinetic energy of the electrons is converted to potential energy of the field, increasing the amplitude of the oscillations. The oscillations excited in the catcher cavity are coupled out through a coaxial cable or waveguide. The spent electron beam, with reduced energy, is captured by a collector electrode. To make an oscillator, the output cavity can be coupled to the input cavity(s) with a coaxial cable or waveguide.

Plasma railguns appear in two principal topologies, linear and coaxial. Linear railguns consist of two flat plate electrodes separated by insulating spacers and accelerate sheet armatures. Coaxial railguns accelerate toroidal plasma armatures using a hollow outer conductor and a central, concentric, inner conductor. Linear plasma railguns place extreme demands on their insulators, as they must be an electrically insulating, plasma-facing vacuum component which can withstand both thermal and acoustic shocks.

Twin-lead consists of a pair of conductors held apart by a continuous insulator. By holding the conductors a known distance apart, the geometry is fixed and the line characteristics are reliably consistent. It is lower loss than coaxial cable because the characteristic impedance of twin-lead is generally higher than coaxial cable, leading to lower resistive losses due to the reduced current. However, it is more susceptible to interference.

Short coaxial cables are commonly used to connect home video equipment, in ham radio setups, and in NIM. While formerly common for implementing computer networks, in particular Ethernet ("thick" 10BASE5 and "thin" 10BASE2), twisted pair cables have replaced them in most applications except in the growing consumer cable modem market for broadband Internet access. Long distance coaxial cable was used in the 20th century to connect radio networks, television networks, and Long Distance telephone networks though this has largely been superseded by later methods (fibre optics, T1/E1, satellite). Shorter coaxials still carry cable television signals to the majority of television receivers, and this purpose consumes the majority of coaxial cable production.

Diagram of a modern hybrid fiber-coaxial cable television system. At the regional headend, the TV channels are sent multiplexed on a light beam which travels through optical fiber trunklines, which fan out from distribution hubs to optical nodes in local communities. Here the light signal from the fiber is translated to a radio frequency electrical signal, which is distributed through coaxial cable to individual subscriber homes. In the most common system, multiple television channels (as many as 500, although this varies depending on the provider's available channel capacity) are distributed to subscriber residences through a coaxial cable, which comes from a trunkline supported on utility poles originating at the cable company's local distribution facility, called the "headend".

A Motorola connector also known as a motorola antenna plug, a male DIN 41585, or simply a DIN connector, is a common coaxial cable RF connector used primarily in the automotive industry for connecting the coaxial feedline from the antenna to the radio receiver. It is also sometimes used for connecting scanner antennas to scanners. The male plug somewhat resembles an RCA connector in size and shape, but instead of surrounding the pin, the sleeve is "folded" back over the coax. The pin is soldered to the center conductor of the coaxial cable coming from the antenna, and the grounded side forms a 1.5 inch (38 mm) long sleeve around the coax.

The primary benefit of using optical fibre for a satellite TV IF distribution system is that the fibre can carry the entire received spectrum on one cable, which can then be split to provide for multiple tuners, without requiring a separate feed from the antenna to each tuner. Additional outlets can be added to increase the number of receivers within one home without accessing the central antenna or main infrastructure. Fibre cable is cheap in long run, retailing at about twice the price of equivalent copper coaxial cable, but replacing four runs of coaxial cable with a single fibre cable. It is also much smaller than the coaxial signal cable used for electrical IF distribution, but robust and flexible.

Lock-ring DC coaxial connectors. The knurled barrel allows the plug to be secured to jacks that have mating male threads. A 'lock-tab DC coaxial connector' (also called 'bayonet lock') offers a compromise that resists unplugging, but which will disengage when pulled hard enough. This connector uses small metal tab protrusions on the connector barrel to lock the plug in place, requiring a special push-and-rotate motion to engage the locks.

Coaxial cables have acceptably small losses for frequencies up to about 5 GHz. For microwave frequencies greater than 5 GHz, the losses (due mainly to the dielectric separating the inner and outer tubes being a non-ideal insulator) become too large, making waveguides a more efficient medium for transmitting energy. Coaxial cables often use a perforated dielectric layer to separate the inner and outer conductors in order to minimize the power dissipated by the dielectric.

Coaxial cable feedline emerging from a VHF ground plane antenna. Coaxial cable is probably the most widely used type of feedline, used for frequencies below the microwave (SHF) range. It consists of a wire center conductor and a braided or solid metallic "shield" conductor, usually copper or aluminum surrounding it. The center conductor is separated from the outer shield by a dielectric, usually plastic foam, to keep the separation between the two conductors precisely constant.

In other types of cable, such as twin lead, the fill factor can be much smaller. Regardless, any cable intended for radio frequencies will have its velocity factor (as well as its characteristic impedance) specified by the manufacturer. In the case of coaxial cable, where F=1, the velocity factor is solely determined by the sort of dielectric used as specified here. For example, a typical velocity factor for coaxial cable is .

These are notch filters usually in an array of six, eight, and sometimes four units. They separate the transmitter and receiver signals from each other so one antenna and coaxial line can be utilized. While this solution is very efficient and easy to install, factors such as humidity and temperature can affect the performance of duplexers, so in most configurations a dryer is installed to keep humidity out of the duplexers and coaxial cable, along with heated buildings in which they are installed in. Excellent quality coaxial cable, connectors, and antennas must also be used, as a single-antenna is not as forgiving as a dual antenna system since any RF leakage or poor connection can greatly decay the reliability and performance of the repeater.

Coaxial cable cutaway (not to scale) Coaxial cable conducts electrical signal using an inner conductor (usually a solid copper, stranded copper or copper plated steel wire) surrounded by an insulating layer and all enclosed by a shield, typically one to four layers of woven metallic braid and metallic tape. The cable is protected by an outer insulating jacket. Normally, the outside of the shield is kept at ground potential and a signal carrying voltage is applied to the center conductor. The advantage of coaxial design is that with differential mode, equal push-pull currents on the inner conductor, and inside of the outer conductor, the signal's electric and magnetic fields are restricted to the dielectric, with little leakage outside the shield.

The mechanism, which was first unveiled in 1976 as the Atwood watch and patented in 1980, was called the coaxial escapement.

CEA-909-A is an update to CEA-909 that enables a single coaxial cable to connect smart antennas to smart antenna-capable DTV sets. A weakness of CEA-909 was that it required another control cable in addition to the coaxial cable. This revision was first approved by the Consumer Electronics Association R4 Video Systems Committee on 6 June 2007 and ANSI public review closed on 1 October 2007. After editorial review, it was published in December 2007.

Coaxial cables are commonly used at audio frequencies and above for convenience. A coaxial cable has a conductive wire inside a conductive tube, separated by a dielectric layer. The current flowing on the surface of the inner conductor is equal and opposite to the current flowing on the inner surface of the outer tube. The electromagnetic field is thus completely contained within the tube, and (ideally) no energy is lost to radiation or coupling outside the tube.

Straight-through MDI to MDI-X connection for 10BASE-T The popular Ethernet family defines common medium dependent interfaces. For 10BASE5, connection to the coaxial cable was made with either a vampire tap or a pair of N connectors. For 10BASE2, the connection to the coaxial cable was typically made with a single BNC connector to which a T-piece was attached. For twisted pair cabling 8P8C, modular connectors are used (often incorrectly called "RJ45" in this context).

Poynting vector in a coaxial cable, shown in red. For example, the Poynting vector within the dielectric insulator of a coaxial cable is nearly parallel to the wire axis (assuming no fields outside the cable and a wavelength longer than the diameter of the cable, including DC). Electrical energy delivered to the load is flowing entirely through the dielectric between the conductors. Very little energy flows in the conductors themselves, since the electric field strength is nearly zero.

A coax balun is a cost-effective method of eliminating feeder radiation, but is limited to a narrow set of operating frequencies. One easy way to make a balun is to use a length of coaxial cable equal to half a wavelength. The inner core of the cable is linked at each end to one of the balanced connections for a feeder or dipole. One of these terminals should be connected to the inner core of the coaxial feeder.

Shielding the coaxial cable acts as a Goubau line USB cable with a ferrite bead as a sheath current filter Sheath current filter for high-power lines A sheath current is a form of charge transfer in wires. Sheath currents can run along the outer sheath of a coaxial cable. This can be caused by a geographically proximate or remote ground potential. Sheath currents may lower the efficiency of transmission and can interfere with nearby electronic devices.

The configuration can also be used in helicopter designs termed coaxial rotors, where similar issues and principles of torque apply. Contra- rotating propellers should not be confused with counter-rotating propellers, a term which describes non-coaxial propellers on separate shafts; one turning clockwise and the other counter-clockwise. Tandem-rotor helicopters such as the CH-47 Chinook also use a counter-rotating arrangement. The efficiency of a contra-rotating prop is somewhat offset by its mechanical complexity.
|
|
While several nations experimented with contra-rotating propellers in aircraft, only the United Kingdom and Soviet Union produced them in large numbers. The U.S. worked with several prototypes, including the tail-sitting Convair XFY and Lockheed XFV "Pogo" VTOL fighters, but jet engine technology was advancing rapidly and the designs were deemed unnecessary. Some helicopters use contra-rotating coaxial rotors mounted one above the other. The H-43 Huskie helicopter uses non-coaxial intermeshing rotors turning in opposite directions.

CoaXPress (CXP) is a digital interface standard developed for high speed image data transmission in machine vision applications. The name is a portmanteau of 'express' (as in express train) and 'coaxial' to emphasize CoaXPress is faster than other standards (e.g. Camera Link, or GigE Vision) and uses 75 ohm coaxial cables as the physical transmission medium. CoaXPress is mostly used in digital imaging applications but it is also suitable for high-speed transmission of universal digital data.

The Sydney–Melbourne coaxial cable was officially opened on 9 April 1962 when Prime Minister Robert Menzies, made an interstate direct dial call. The coaxial cable infrastructure supported the introduction of subscriber trunk dialling between the cities and live television link-ups. After its commissioning in April 1962 the cable carried telegraph and telephone traffic. It also provided the first inter-city television transmission in Australia, allowing simultaneous television broadcasting in Melbourne and Sydney for the first time.

DS3 interconnect cables must be made with true 75-ohm coaxial cable and connectors. Cables or connectors which are 50 ohms or which significantly deviate from 75 ohms will result in signal reflections which will lower the performance of the connection, possibly to the point of not working. GR-139-CORE, Generic Requirements for Central Office Coaxial Cable, defines type 734 and 735 cables for this application. Due to losses, there are differing distance limitations for each type of cable.

A ring-shaped 'locking detent' or 'high-retention feature', present on the barrel of some DC coaxial connectors, is a feature intended to prevent accidental disconnection. Typically, this feature is a conical cut-back section of the tip, just behind the insulator that separates the inner from outer contact surfaces. A 'lock- ring DC coaxial connector' uses a captive threaded ring or collar to secure the connection between the plug and jack. This design offers strong resistance to unplugging when used properly.

There is an increased mechanical complexity of the rotor hub. The linkages and swashplates for two rotor systems need to be assembled atop the mast, which is more complex because of the need to drive two rotors in opposite directions. Because of the greater number of moving parts and complexity, the coaxial rotor system is more prone to mechanical faults and possible failure. Coaxial helicopters are also more prone to the "whipping" of blades and blade self- collision according to critics.

Shutter Dial DetailThe M5 has the largest M shutter speed dial. It is coaxial with the shutter button and overhangs the top plate, making for very comfortable and quick manipulation, adjustable without taking the camera from your eye. This ergonomic feature is often cited as one of the M5's paradigmatic advantages, and a non-coaxial variant was later reintroduced as of the M6 TTL (1998). The M5 is the only full-size M with shutter speeds visible in the finder.

Lama V3 model helicopter, with a simplified coaxial rotor system. A recent innovation is that of coaxial electric helicopters. The system's simple direction control and freedom from torque induced yaw have, in recent years, made it a good candidate on small models for beginner and/or indoor use. Models of this type, as in the case of a full-scale helicopter, eliminate rotational torque and can have extremely quick control response, both of which are very pronounced in a CCPM model.

A continuous current, even if small, along the imperfect shield of a coaxial cable can cause visible or audible interference. In CATV systems distributing analog signals the potential difference between the coaxial network and the electrical grounding system of a house can cause a visible "hum bar" in the picture. This appears as a wide horizontal distortion bar in the picture that scrolls slowly upward. Such differences in potential can be reduced by proper bonding to a common ground at the house.

Most well-studied RNA tertiary structures contain examples of coaxial stacking. Some prominent examples are tRNA-Phe, group I introns, group II introns, and ribosomal RNAs. Crystal structures of tRNA revealed the presence of two extended helices that result from coaxial stacking of the amino-acid acceptor stem with the T-arm, and stacking of the D- and anticodon-arms. These interactions within tRNA orient the anticodon stem perpendicularly to the amino-acid stem, leading to the functional L-shaped tertiary structure.

There exists no direct transition between a coaxial line and a SIW: an other planar line have to be used to convert properly the coaxial TEM propagation modes to the TE modes in SIW. Several studies have been carried out to optimize the transition between topologies without being able to determine a universal rule making it possible to draw the absolute transition. The architecture, the frequency range, the used materials, etc. are examples of parameters that make specific the design procedure.

Coaxial cables are used for microwaves, televisions and computers. This was the second transmission medium to be introduced (often called coax), around the mid-1920s. In the center of a coaxial cable is a copper wire that acts as a conductor, where the information travels. The copper wire in coax is thicker than that in twisted-pair, and it is also unaffected by surrounding wires that contribute to electromagnetic interference, so it can provide higher transmission rates than the twisted- pair.

ISA network interface card supporting both coaxial-cable-based 10BASE2 (BNC connector, left) and twisted pair-based 10BASE-T (8P8C connector, right) For signal degradation and timing reasons, coaxial Ethernet segments have a restricted size. Somewhat larger networks can be built by using an Ethernet repeater. Early repeaters had only two ports, allowing, at most, a doubling of network size. Once repeaters with more than two ports became available, it was possible to wire the network in a star topology.

Gunness and Siegel turned their attention to coaxial loudspeakers, known for their desired single-point-source characteristics but also for various problems associated with intermodulation distortion—the low frequencies modulating the highs—and undesirable sonic variations in off-axis frequency response. Other negative aspects of traditional coaxial designs were their bulky weight and their lengthy axis requiring deep enclosures. Gunness and Siegel set about designing a coaxial with a common magnet for both low and high frequency drivers for weight savings and for reduced axial length, and a horn was developed to direct as much high frequency energy as possible away from the low frequency cone. A DSP solution called "Temporal Equalization" (TQ) was used to cancel out any remaining high frequency energy arriving at the moving cone.

Cabling for free to air TV requires the following: # An antenna # Coaxial cable # TV outlets Antenna types vary depending on location; an urban area with nearby transmitters will require a smaller antenna than a rural site with distant stations. The antenna is often mounted outdoors on the roof or a tower. A coaxial or twinlead cable is run from the antenna to the location where the television is located. One common type of cable is designated RG-6 Tri-shield or quad-shield cable.

Schematic diagrams of the three base-stacking conformational isomers of the Holliday junction. The two stacked conformers differ in which sets of two arms are bound by coaxial stacking: at left, the stacks are red–blue and cyan–magenta, while at right the stacks are red–cyan and blue–magenta. The bases nearest to the junction point determine which stacked isomer dominates. Holliday junctions may exist in a variety of conformational isomers with different patterns of coaxial stacking between the four double-helical arms.

In this latter machine, he made a tethered flight on 12 September 1906.1935 photo of Ellehammer's disc-rotor compound helicopter model Ellehammer's later inventions included a successful triplane and helicopter. His helicopter was a coaxial machine. A famous photo shows it hovering in 1914, though there is no evidence that it was successful in achieving horizontal flight. Ellehammer later studied a disc-rotor configuration - a compound helicopter with coaxial blades that extended from the hub for hover, and retracted for high speed vertical flight.

They introduce standing waves, which increase losses and can even result in cable dielectric breakdown with high-power transmission. In analog video or TV systems, reflections cause ghosting in the image; multiple reflections may cause the original signal to be followed by more than one echo. If a coaxial cable is open (not connected at the end), the termination has nearly infinite resistance, which causes reflections. If the coaxial cable is short-circuited, the termination resistance is nearly zero, which causes reflections with the opposite polarity.

Video can be transmitted or transported in a variety of ways including wireless terrestrial television as an analog or digital signal, coaxial cable in a closed circuit system as an analog signal. Broadcast or studio cameras use a single or dual coaxial cable system using serial digital interface (SDI). See List of video connectors for information about physical connectors and related signal standards. Video may be transported over networks and other shared digital communications links using, for instance, MPEG transport stream, SMPTE 2022 and SMPTE 2110.

Additionally, a complex triple joint seal may exist at the breech of the bore, which can often pose an extreme engineering challenge. Coaxial accelerators require insulators only at the breech, but the plasma armature in that case is subject to the "blow-by" instability. This is an instability in which the magnetic pressure front can out-run or "blow-by" the plasma armature due to the radial dependence of acceleration current density, drastically reducing device efficiency. Coaxial accelerators use various techniques to mitigate this instability.

For its physical layer 10BASE5 uses cable similar to RG-8/U coaxial cable but with extra braided shielding. This is a stiff, diameter cable with an impedance of 50 ohms, a solid center conductor, a foam insulating filler, a shielding braid, and an outer jacket. The outer jacket is often yellow-to-orange fluorinated ethylene propylene (for fire resistance) so it often is called "yellow cable", "orange hose", or sometimes humorously "frozen yellow garden hose". 10BASE5 coaxial cables had a maximum length of .

The signal to be measured is fed to one of the input connectors, which is usually a coaxial connector such as a BNC or UHF type. Binding posts or banana plugs may be used for lower frequencies. If the signal source has its own coaxial connector, then a simple coaxial cable is used; otherwise, a specialized cable called a "scope probe", supplied with the oscilloscope, is used. In general, for routine use, an open wire test lead for connecting to the point being observed is not satisfactory, and a probe is generally necessary. General-purpose oscilloscopes usually present an input impedance of 1 megohm in parallel with a small but known capacitance such as 20 picofarads.The 20 picofarad value is typical for scope bandwidths around 100 MHz; for example, a 200 MHz Tektronix 7A26 input impedance is 1M and 22 pF.

SMA (SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling mechanism. The connector has a 50 Ω impedance. SMA is designed for use from DC (0 Hz) to 18 GHz, and is most commonly used in microwave systems, hand-held radio and mobile telephone antennas, and more recently with WiFi antenna systems and USB software-defined radio dongles. It is also commonly used in radio astronomy, particularly at higher frequencies (5 GHz+).

However the third and fourth "120 mm" oscillating turret prototypes had a single 7.5 mm AA machine gun and a second 7.5 mm coaxial machine gun. For the production vehicles it was considered to install a coaxial 20 mm gun; lighter armoured targets could then be engaged without depleting the limited ammunition stock in the turret magazines. Despite the auto-loader, the crew was four: a second man was seated in the hull, functioning as radio-operator, but mainly needed to replenish the turret magazines, holding nine rounds each, from the hull ammunition stocks.

The majority of modern transmitting equipment is designed to operate with a resistive load fed via coaxial cable of a particular characteristic impedance, often 50 ohms. To connect the power stage of the transmitter to this coaxial cable transmission line a matching network is required. For solid state transmitters this is typically a broadband transformer which steps up the low impedance of the output devices to 50 ohms. A tube transmitter will contain a tuned output network, most commonly a PI network, that steps the load impedance which the tube requires down to 50 ohms.

Modern Ethernet, the most common data networking standard, can use UTP cables. Twisted-pair cabling is often used in data networks for short and medium-length connections because of its relatively lower costs compared to optical fiber and coaxial cable. As UTP cable bandwidth has improved to match the baseband of television signals, UTP is now used in some video applications, primarily in security cameras. As UTP is a balanced transmission line, a balun is needed to connect to unbalanced equipment, for example any using BNC connectors and designed for coaxial cable.

The USS Aeolus Association website has a photo of a display of the first three types of Project Caesar cables. The upgrades made possible by the multiplexed coaxial cable were designated Caesar Phase III. Caesar Phase IV was associated with major upgrades in shore processing with Digital Spectrum Analysis (DSA) backfits at the stations replacing original equipment during the late 1960s. In September 1972 a third generation coaxial cable, again based on commercial developments at Bell Labs and designated SD-C, was installed for the system terminating at Naval Facility Centerville Beach, California.

It differs from other shielded cables because the dimensions of the cable and connectors are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line. Coaxial cable was used in the first (1858) and following transatlantic cable installations, but its theory wasn't described until 1880 by English physicist, engineer, and mathematician Oliver Heaviside, who patented the design in that year (British patent No. 1,407). In his 1880 British patent, Oliver Heaviside showed how coaxial cable could eliminate signal interference between parallel cables.

Semi- rigid coax assembly Semi-rigid coax installed in an Agilent N9344C 20GHz spectrum analyser Semi-rigid cable is a coaxial form using a solid copper outer sheath. This type of coax offers superior screening compared to cables with a braided outer conductor, especially at higher frequencies. The major disadvantage is that the cable, as its name implies, is not very flexible, and is not intended to be flexed after initial forming. (See "hard line") Conformable cable is a flexible reformable alternative to semi-rigid coaxial cable used where flexibility is required.

Broadband cable Internet access requires a cable modem at the customer's premises and a cable modem termination system (CMTS) at a cable operator facility, typically a cable television headend. The two are connected via coaxial cable or a hybrid fibre-coaxial (HFC) plant. While access networks are sometimes referred to as last-mile technologies, cable Internet systems can typically operate where the distance between the modem and the termination system is up to . If the HFC network is large, the cable modem termination system can be grouped into hubs for efficient management.

A counterbore in a metal plate A counterbore (symbol: ⌴) is a cylindrical flat-bottomed hole that enlarges another coaxial hole, or the tool used to create that feature. A counterbore hole is typically used when a fastener, such as a socket head cap screw, is required to sit flush with or below the level of a workpiece's surface. Whereas a counterbore is a flat-bottomed enlargement of a smaller coaxial hole, a countersink is a conical enlargement of such. A spotface often takes the form of a very shallow counterbore.

The studio monitors over the window are a pair of UREI 813s, each of which has a 15-inch coaxial (below, with the blue rectangle), and a plain 15-inch driver (above). The high frequency component of the coax is a horn, which includes blue foam rubber to attenuate undesired anomalies. Coaxial loudspeakers in professional audio enable sound from two drivers to come from one source. This characteristic allows a wider field of listening to a synchronized summation of speaker drivers than loudspeaker enclosures containing physically separated drivers.

Cable Internet provides access using a cable modem on hybrid fiber coaxial wiring originally developed to carry television signals. Either fiber-optic or coaxial copper cable may connect a node to a customer's location at a connection known as a cable drop. In a cable modem termination system, all nodes for cable subscribers in a neighborhood connect to a cable company's central office, known as the "head end." The cable company then connects to the Internet using a variety of means – usually fiber optic cable or digital satellite and microwave transmissions.

Unlike FTTP, FTTN often uses existing coaxial or twisted-pair infrastructure to provide last mile service and is thus less costly to deploy. In the long term, however, its bandwidth potential is limited relative to implementations that bring the fiber still closer to the subscriber. A variant of this technique for cable television providers is used in a hybrid fiber-coaxial (HFC) system. It is sometimes given the acronym FTTLA (fiber-to-the-last- amplifier) when it replaces analog amplifiers up to the last one before the customer (or neighborhood of customers).

Mason and Sykes published the definitive paper on the method in 1937. Mason was also the first to suggest a distributed-element acoustic filter in his 1927 doctoral thesis, and a distributed-element mechanical filter in a patentMason (1961) filed in 1941. Mason's work was concerned with the coaxial form and other conducting wires, although much of it could also be adapted for waveguide. The acoustic work had come first, and Mason's colleagues in the Bell Labs radio department asked him to assist with coaxial and waveguide filters.

While material substance is not required for electromagnetic waves to propagate, such waves are usually affected by the transmission media they pass through, for instance by absorption or by reflection or refraction at the interfaces between media. Technical devices can therefore be employed to transmit or guide waves. Thus, an optical fiber or a copper cable are used as transmission media. Coaxial cable, one example of a transmission medium Electromagnetic radiation can be transmitted through an optical medium, such as optical fiber, or through twisted pair wires, coaxial cable, or dielectric- slab waveguides.

The communications cables are attached below the electric power lines, in a vertical space along the pole designated the communications space. The communications space is separated from the lowest electrical conductor by the communication worker safety zone, which provides room for workers to maneuver safely while servicing the communication cables, avoiding contact with the power lines. The most common communication cables found on utility poles are copper or fibre optic cable (FOC) for telephone lines and coaxial cable for cable television (CATV). Coaxial or optical fibre cables linking computer networks are also increasingly found on poles in urban areas.

If an electronic device with a long coaxial aerial lead is disturbed by a signal from a HF transmitter then the braid of the coaxial should be considered as a path of entry of RF into the affected device. One additional feature which can assist a braid breaker is the use of an RF ground, a quarter wavelength of wire will act as an RF ground even when it goes nowhere. This is because the quarterwave transforms the infinite impedance into a zero impedance. The quarterwave length of wire can be regarded as an artificial earth for RF purposes.

Cross-section through a coaxial cable showing shielding and other layers One example is a shielded cable, which has electromagnetic shielding in the form of a wire mesh surrounding an inner core conductor. The shielding impedes the escape of any signal from the core conductor, and also prevents signals from being added to the core conductor. Some cables have two separate coaxial screens, one connected at both ends, the other at one end only, to maximize shielding of both electromagnetic and electrostatic fields. The door of a microwave oven has a screen built into the window.

The aircraft consisted of an open steel tube framework, within which the engine, fuel tank, controls and pilot were situated, together with a tail assembly with plywood tail surfaces. The tailwheel landing gear was installed with the mainwheels on outriggers and with an additional small wheel at the front to avoid nosing-over during landing. Power was provided by a 240 HP Hispano radial engine which propelled the two contra-rotating, coaxial rotors. The coaxial rotor design was chosen because with the rotors turning in opposite directions the torque from one rotor was canceled out by the torque produced by the other rotor.
|
|
Further, electric and magnetic fields outside the cable are largely kept from interfering with signals inside the cable, if unequal currents are filtered out at the receiving end of the line. This property makes coaxial cable a good choice both for carrying weak signals, that cannot tolerate interference from the environment, and for stronger electrical signals, that must not be allowed to radiate or couple into adjacent structures or circuits. Larger diameter cables and cables with multiple shields have less leakage. Common applications of coaxial cable include video and CATV distribution, RF and microwave transmission, and computer and instrumentation data connections.

Crimp connections are used typically to fix connectors, such as BNC connectors, to coaxial cablesTypical crimp BNC connector quickly, as an alternative to soldered connections. Typically the male connector is crimp-fitted to a cable, and the female attached, often using soldered connections, to a panel on equipment. A special power or manual toolTypical manual crimp tool for fitting BNC and other coaxial connectors to cables is used to fit the connector. Wire strippers which strip outer jacket, shield braid, and inner insulation to the correct lengths in one operationTypical coax one-operation stripper are used to prepare the cable for crimping.

The F connector (also F-type connector) is a coaxial RF connector commonly used for "over the air" terrestrial television, cable television and universally for satellite television and cable modems, usually with RG-6/U cable or with RG-59/U cable. The F connector was invented by Eric E. Winston in the early 1950s while working for Jerrold Electronics on their development of cable television.Electrical Connector. US Patent 3,537,065 by Eric Winston In the 1970s, it became commonplace on VHF, and later UHF, television antenna connections in the United States, as coaxial cables replaced twin-lead.

High- frequency signal lines may attenuate or prevent sheath currents using a sheath current filter which is applied to a coaxial cable in or near the device. In the simplest case, this is a ferrite bead, it includes the coaxial inner and outer conductor and acts as a common-mode choke. At the same time, a ferrite bead has a transformer effect, so that a useful signal is confirmed as differential-mode. To increase the inductance compared to the unwanted common mode signal component, the cable can also be repeatedly passed through or wound around the bead.

070808 ntrautanen.fi The system displays video in analog RGB PAL or NTSC through a proprietary DB23M connector and in NTSC mode the line frequency is HSync for standard video modes, which is compatible with NTSC television and CVBS/RGB video, but out of range for most VGA-compatible monitors, while a multisync monitor is required for some of the higher resolutions. This connection can also be genlocked to an external video signal. The system was bundled with an RF adapter to provide output on televisions with a coaxial RF input, while monochrome composite video is available via an RCA connector (also coaxial).

The APC-7 connector (also referred to as a 7 mm connector) is a precision coaxial connector used on laboratory microwave test equipment for frequencies up to 18 GHz. APC-7 connectors are advantageous because they have a low- reflection coefficient, make repeatable coaxial connections, and are genderless. The connectors are expensive, so they are seldom used outside the laboratory where their cost can be justified by their accuracy and convenience. Due to their high cost, their 18 GHz frequency limitation, and new laboratory practices,Connections at the instrument front panel don't need to be repeatable because those connections remain mated during tests.

The term "channel" has two different meanings. In one meaning, a channel is the physical medium that carries a signal between the transmitter and the receiver. Examples of this include the atmosphere for sound communications, glass optical fibers for some kinds of optical communications, coaxial cables for communications by way of the voltages and electric currents in them, and free space for communications using visible light, infrared waves, ultraviolet light, and radio waves. Coaxial cable types are classified by RG type or "radio guide", terminology derived from World War II. The various RG designations are used to classify the specific signal transmission applications.

|
Coaxial cable is used to carry cable television signals into cathode ray tube and flat panel television sets. Cable television is a system of broadcasting television programming to paying subscribers via radio frequency (RF) signals transmitted through coaxial cables or light pulses through fiber-optic cables. This contrasts with traditional terrestrial television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. In the 2000s, FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables.

The Enigma is fitted with the turret of a Russian BMP-3 with 100 mm cannon, coaxial 30 mm machine gun, coaxial 7.62-mm machine gun, and smoke grenade launchers. The 100 mm cannon auto-loader is able to fire 10 rounds per minute, firing HE-FRAG projectiles beside ordinary and laser-guided anti-tank ammunition. It can launch laser-guided projectiles in the same manner as ordinary rounds. The 30 mm gun machine is used against ground and low flying air targets with a range of 2 km against ground targets and 4 km against helicopters.

Time domain reflectometry has also been utilized to monitor slope movement in a variety of geotechnical settings including highway cuts, rail beds, and open pit mines (Dowding & O'Connor, 1984, 2000a, 2000b; Kane & Beck, 1999). In stability monitoring applications using TDR, a coaxial cable is installed in a vertical borehole passing through the region of concern. The electrical impedance at any point along a coaxial cable changes with deformation of the insulator between the conductors. A brittle grout surrounds the cable to translate earth movement into an abrupt cable deformation that shows up as a detectable peak in the reflectance trace.

The Leclerc is also equipped with a 12.7 mm coaxial machine gun and a remote-controlled 7.62mm machine gun, whereas most other NATO tanks use 7.62mm weapons for both their coaxial and top machine gun mounts; the major exception is the American M1 Abrams, which has a 7.62mm coaxial machine gun and two top-mounted machine guns, one 7.62mm and one 12.7mm. The Leclerc has the GALIX combat vehicle protection system from GIAT, which fires a variety of smoke grenades and infra red screening rounds, as well as anti-personnel grenades. The hull and the turret are made of welded steel fitted with modular armour, which can be replaced easily for repair or upgraded over the years. The French army in the late seventies rejected Chobham armour as being overly specialised in its optimisation to defeat hollow charge-weapons; it therefore opted to develop their own composite arrangement to defeat both hollow charge and sabot round.

The isolation must be put in the CATV RF feed instead. The internal design of the CATV box should have provided for this. Ground loop issues with television coaxial cable can affect any connected audio devices such as a receiver. Even if all of the audio and video equipment in, for example, a home theatre system is plugged into the same power outlet, and thus all share the same ground, the coaxial cable entering the TV is sometimes grounded by the cable company to a different point than that of the house's electrical ground creating a ground loop, and causing undesirable mains hum in the system's speakers.

Electric assisted turbochargers are turbochargers employing a coaxial electric motor to overcome the time lag of the exhaust gas driven turbine. The electric motor supports the exhaust gas driven turbine at low-end revolutions to compress enough air into engine's intake, while it can be configured as an alternator to extract energy from the exhaust gas driven turbine at high-end revs, which would otherwise need be bypassed via wastegate and eventually replacing the current mechanically driven alternator. Special consideration need be given to the coaxial electric motor operating in proximity of a hot turbine at very high rotational speed (up to 100,000 rpm).

According to the CBS press release issued for the day the program aired, Premiere originated from CBS-TV's Studio 57 in New York City and was then transmitted from the studio by coaxial cable to CBS Master Control, which then sent it by telephone circuit to the local CBS transmitter for its New York City broadcast. The four other participating CBS affiliates received the show by coaxial cable. All five participating stations used their regular transmitters to send the broadcast signal out on the station's usual TV channel. Local newspaper television listings warned TV owners that they would be able to hear but not see the telecast.

The signal is then passed through a coaxial cable into the residence to the satellite television receiver, a set-top box next to the television. The reason for using the LNB to do the frequency translation at the dish is so that the signal can be carried into the residence using cheap coaxial cable. To transport the signal into the house at its original Ku band microwave frequency would require an expensive waveguide, a metal pipe to carry the radio waves. The cable connecting the receiver to the LNB are of the low loss type RG-6, quad shield RG-6, or RG-11.

Satellite television, cable television and over-the-air (OTA) signals as well as locally generated programming such as hotel guest welcome screens and other hotel information and services can be distributed via an L band type system, COM3000 HD/4K Pro:Idiom headend from Technicolor, or an IPTV type distribution system. In most hotels, a television signal provided by a satellite television or cable television provider or OTA antenna is transmitted over a hotel coaxial cable network. Most hotels today are wired only with coaxial cables. Some newer hotels are pre-wired with UTP or CAT-5/6 cabling, which enables IP-based hotel television services.

Standoff insulators are used to keep them away from parallel metal surfaces. Coaxial lines largely solve this problem by confining virtually all of the electromagnetic wave to the area inside the cable. Coaxial lines can therefore be bent and moderately twisted without negative effects, and they can be strapped to conductive supports without inducing unwanted currents in them, so long as provisions are made to ensure differential mode signal push-pull currents in the cable. In radio-frequency applications up to a few gigahertz, the wave propagates primarily in the transverse electric magnetic (TEM) mode, which means that the electric and magnetic fields are both perpendicular to the direction of propagation.

Due to TDC's very dominant position, The Danish Business Authority has ordered TDC to open its coaxial network to other competitors since 2009. This has however not brought any new competitors to compete with TDC on DOCSIS 3 connections; this is because TDC has set up its system in such a way that any customer has to buy regular cable TV from TDC before the customer can purchase any DOCSIS 3 connection from a competitor. In 2014, The Danish Business Authority started taking steps towards new regulation demanding that TDC should open its coaxial network in terms of both cable TV and DOCSIS 3 to arbitrage competitors.

Coaxial weapons are usually aimed by use of the main gun control. It is usually used to engage infantry or other "soft" targets where use of shots from the main gun would be dangerous, ineffective or wasteful. Some weapons such as the M40 recoilless rifle and the Mk 153 Shoulder-Launched Multipurpose Assault Weapon have a smaller caliber spotting rifle mounted in coaxial fashion to the barrel or launch tube. These weapons fire special cartridges designed to mimic the ballistic arc of the host weapon's ammunition, using tracer or point-detonating rounds so that a gunner can easily determine where a shot will land in order to place fire accurately.

Merkava Mk 3D Baz with LIC upgrades These are Merkava Mark III BAZ or Mark IV tanks, converted for urban warfare. The LIC designation stands for "Low intensity conflict", underlining its emphasis on counter-insurgency, street-to-street inner-city asymmetrical type warfare of the 21st century. The Merkava is equipped with a turret 12.7 mm caliber coaxial machine gun, which enables the crew to lay down fairly heavy cover fire without using the main gun (which is relatively ineffective against individual enemy combatants). Like the new remote-operated weapon station, the coaxial machine-gun is fired from inside the tank without exposing the crew to small-arms fire and snipers.

Signal terminators are designed to specifically match the characteristic impedances at both cable ends. For many systems, the terminator is a resistor, with a value chosen to match the characteristic impedance of the transmission line, and chosen to have acceptably low parasitic inductance and capacitance at the frequencies relevant to the system. Examples include 75-ohm resistors often used to terminate 75-ohm video transmission coaxial cables. Types of transmission line cables include balanced line such as ladder line, and twisted pairs (Cat-6 Ethernet, Parallel SCSI, ADSL, Landline Phone, XLR audio, USB, Firewire, Serial); and unbalanced lines such as coaxial cable (Radio antenna, CATV, 10BASE5 Ethernet).

When used for video signals on the computer side, the pins are female but the coaxial connectors in the large positions are male. The coaxial connectors carry the video signal split into red, green/gray, and blue; the standard signal pins carry four grounds, three "sense" pins used to communicate with the monitor, vertical sync, horizontal sync, and a composite sync signal. The 13W3 connector can be converted into a standard VGA connector using commonly available cables and adapters. This allows multisync monitors, which became prevalent in personal computing in the late 1980s, to be used with these workstations as long as they are sync-on-green compatible.

A car audio speaker with a coaxial tweeter in front of the woofer Coaxial speakers in automobiles are 2- or 3-way loudspeakers in which the tweeter, or the tweeter and a mid-range driver, are mounted in front of the woofer, partially obscuring it. The advantage of this design is the ability to use a smaller area, hence their popularity in car audio. The low frequency sound waves from the woofer are not reduced too much by the drivers in their path. Without time-alignment correction, the sound from the tweeter may arrive slightly before the sound from the woofer; this misalignment is not generally addressed in automobile sound systems.
|
|
Coaxial loudspeakers have been used in concerts for on-stage foldback duties, giving musicians a more even sound field because of the single-source characteristic. As well, the enclosure may be made more compact. In the 1980s, Professional Audio Systems (PAS), using Time Alignment technology from Ed Long, sold the popular SW series of compact stage wedges, offered with a 12- or 15-inch woofer, and having a projecting high-frequency horn as in the 604. Other stage monitors using coaxial designs are made by Clair Brothers, L-Acoustics, Radian Audio Engineering, RCF, Beyma, dB Technologies, Fulcrum Acoustic, and Rat Sound in partnership with Eastern Acoustic Works.

VGA BNC connectors Some high-end monitors and video cards use multiple BNC connectors instead of a single standard VGA connector, providing a higher quality connection with less crosstalk by utilizing five separate 75ohm coaxial cables. Within a 15-pin connector, the red, green, and blue signals (pins 1, 2, 3) cannot be shielded from each other, so crosstalk is possible within the 15-pin interconnect. BNC prevents crosstalk by maintaining full coaxial shielding through the circular connectors, but the connectors are very large and bulky. The requirement to press and turn the plug shell to disconnect requires access space around each connector to allow grasping of each BNC plug shell.

When the ATU must be located near the radio for convenient adjustment, any significant SWR will increase the loss in the feedline. For that reason, when using an ATU at the transmitter, low-loss, high-impedance feedline is a great advantage (open-wire line, for example). A short length of coaxial line with low loss is acceptable, but with longer coaxial lines the greater losses, aggravated by SWR, become very high. It is important to remember that when an ATU is placed near the transmitter and far from the antenna, even though the ATU matches the transmitter to the line there is no change in the line beyond the ATU.

Ka-32 helicopter with coaxial contra-rotating rotors, in 1989 Contra- rotating, also referred to as coaxial contra-rotating, is a technique whereby parts of a mechanism rotate in opposite directions about a common axis, usually to minimise the effect of torque. Examples include some aircraft propellers, resulting in the maximum power of a single piston or turboprop engine to drive two propellers in opposite rotation. Contra-rotating propellers are also common in some marine transmission systems, in particular for large speed boats with planing hulls. Two propellers are arranged one behind the other, and power is transferred from the engine via planetary gear transmission.

All broadcast satellite transmissions see it as the DVB-S Transport Stream. It is usually made up of one or more television channels with accompanying audio, sometimes with additional audio- only or data transmission channels. When that composite data transmission path, asynchronous but formatted data, travels through space as RF, it is usually called DVB-S, DVB-T, or ATSC. But when carried on coaxial cable, unmodulated, it is called an ASI signal. It is a one-way transmission, similar to RS-232 asynchronous data—a stream of raw but formatted zeros and ones—designed to primarily travel through coaxial cable at speeds that range from 6-200 megabits per second.

Cities rely to a lesser extent on hydrocarbon fuels such as gasoline and natural gas for transportation, heating, and cooking. Telecommunications infrastructure such as telephone lines and coaxial cables also traverse cities, forming dense networks for mass and point-to-point communications.Latham et al. (2009), pp. 169–170.

The second solution is to route cables away from trouble. Beyond this, there are particular cable designs that minimize electromagnetic pickup and transmission. Three of the principal design techniques are shielding, coaxial geometry, and twisted-pair geometry. Shielding makes use of the electrical principle of the Faraday cage.

Early Shermans that had a periscopic sight for the main gun mounted in the turret roof possessed a small thick mantlet that only covered the hole where the main gun barrel protruded; the exposed barrel of the coaxial machine gun was vulnerable to bullet splash or shrapnel and a small armored cover was manufactured to protect it. When the Sherman was later fitted with a telescopic sight next to the main gun, a larger thick gun mantlet that covered the entire rotor shield including the sight and coaxial machine gun barrel was produced.Reid, p. 215 105 mm-armed Sherman tanks did not have a rotor shield, possessing only the mantlet to cover the opening in the turret front.

There is a long history in electrical engineering of referring to such power plugs — that is to say, plugs with holes instead of prongs — as female, particularly regarding coaxial transmission of electricity, and data communication and computer cables. Type N connectors, and all IEC 60320 "appliance coupler" plugs, and VGA cables with male connectors on the cable and female connectors on the devices are examples of this. That said, while IEC 60320 provides gender-based standards for higher-voltage plugs (such as the cable plugged into a standard computer power supply), they have not yet defined gender-based standards for low-voltage coaxial power connectors such as those discussed herein; i.e., which component is "male" and which is "female".

In 1988, KEF introduced an extension of the coaxial loudspeaker concept. Their Uni-Q driver is a coincident driver, where the two drivers share the same acoustic center and therefore are closer in time alignment. This was made possible by using the then newly affordable powerful yet small neodymium magnets for the tweeter making the whole tweeter assembly small enough, magnet included, to fit inside the woofer's voice coil. Other home audio speaker companies making coaxial speakers include TAD, Cabasse with their 4-way Concentric QC-55 Driver as seen in their flagship model - La Sphère, Hsu, Vandersteen, until recently Theil, and a budget speaker made a few years ago by Insignia.

Naha was known to have made extensive studies on the structural geology of Precambrian era and was credited with compiling an integrated geological history of Precambrian rocks in Ghatsila in Singhbhum of Bihar and in Simla region. Through his studies, he estimated the time of formation and kinematic significance of deformation lamellae in quartz. Migmatites and its architecture, the geometry of reclined folds and the early precambrian terrance of the southern parts of India and central Rajasthan were some of the other foci of his studies. His studies also assisted in developing methodologies for the recognition of angular run conformity in metamorphic terraces as well as the coaxial refolding prior to non- coaxial deformation.

Flying leads are likely to pick up interference, so they are not suitable for low-level signals. Furthermore, the inductance of flying leads make them unsuitable for high frequency signals. Instead, a specific scope probe is used, which uses a coaxial cable to transmit the signal from the tip of the probe to the oscilloscope. This cable has two main benefits: it protects the signal from external electromagnetic interference, improving accuracy for low-level signals; and it has a lower inductance than flying leads, making the probe more accurate for high- frequency signals. Although coaxial cable has lower inductance than flying leads, it has higher capacitance: a typical 50 ohm cable has about 90 pF per meter.

Contra-rotating propellers Contra-rotating propellers on the Rolls-Royce Griffon-powered P-51XR Mustang Precious Metal at the 2014 Reno Air Races Aircraft equipped with contra-rotating propellers, also referred to as CRP, coaxial contra-rotating propellers, or high-speed propellers, apply the maximum power of usually a single piston or turboprop engine to drive two coaxial propellers in contra-rotation. Two propellers are arranged one behind the other, and power is transferred from the engine via a planetary gear or spur gear transmission. Contra-rotating propellers are also known as counter- rotating propellers, although counter-rotating propellers is much more widely used when referring to airscrews on separate shafts turning in opposite directions.

One of the main advantages of HDcctv is that it does not require significant modification for existing CCTV systems designed for analog cameras originally using composite NTSC or PAL video, for which extensive cabling and labor was invested for installation of the original analog system. Since the coaxial cables originally used for the analog system have significant unused data spectrum available, it is a simple matter to just replace the camera and the recorder to obtain nearly seven times higher detail (1920x1080 vs 640x480) than the original camera system. Since coaxial cable is capable of carrying a hundred HDTV channels simultaneously, there is still more unused data capacity available for future resolution improvements.

Bathymetric diagram of the Axial Seamount, showing the 1998 eruption and segmentation between the CoAxial, Axial, and Vance segments of the ridge The first documented eruption on the Juan de Fuca Ridge took place on the Cleft segment in 1986 and 1987. Hydrothermal megaplumes indicated a large rifting event, releasing hydrothermal fluids as a result of lavas being extruded from a dike. A majority of the eruptions along the ridge are dike injection events, where molten rock is extruded between cracks in the crust's sheeted dike layer. Typically eruptive events can be predicted, as they are preceded by large earthquake swarms in the region. A significant event took place in June 1993, lasting 24 days at the CoAxial segment.

Coaxial lines confine virtually all of the electromagnetic wave to the area inside the cable. Coaxial lines can therefore be bent and twisted (subject to limits) without negative effects, and they can be strapped to conductive supports without inducing unwanted currents in them. In radio-frequency applications up to a few gigahertz, the wave propagates in the transverse electric and magnetic mode (TEM) only, which means that the electric and magnetic fields are both perpendicular to the direction of propagation (the electric field is radial, and the magnetic field is circumferential). However, at frequencies for which the wavelength (in the dielectric) is significantly shorter than the circumference of the cable other transverse modes can propagate.

An effect similar to coaxial stacking has been observed in rationally designed DNA structures. DNA origami structures contain a large number of double helixes with exposed blunt ends. These structures were observed to stick together along the edges that contained these exposed blunt ends, due to the hydrophobic stacking interactions.

The reflective axicon or "reflaxicon" was described in 1973 by W. R. Edmonds. The reflaxicon uses a pair of coaxial, conical reflecting surfaces to duplicate the functionality of the transmissive axicon. The use of reflection rather than transmission improves the damage threshold, chromatic aberration, and group velocity dispersion compared to conventional axicons.

The equivalent device for optical fiber is an optical time-domain reflectometer. Time-domain transmissometry (TDT) is an analogous technique that measures the transmitted (rather than reflected) impulse. Together, they provide a powerful means of analysing electrical or optical transmission media such as coaxial cable and optical fiber. Variations of TDR exist.

Another benefit arising from a coaxial design includes increased payload for the same engine power; a tail rotor typically wastes some of the available engine power that would be fully devoted to lift and thrust with a coaxial design. Reduced noise is the main advantage of the configuration; some of the loud "spanking" sound associated with conventional helicopters arises from interaction between the airflows from the main and tail rotors, which in some designs can be severe. Also, helicopters using coaxial rotors tend to be more compact (with a smaller footprint on the ground), though at the price of increased height, and consequently have uses in areas where space is at a premium; several Kamov designs are used in naval roles, being capable of operating from confined spaces on the decks of ships, including ships other than aircraft carriers (an example being the Kara-class cruisers of the Russian navy, which carry a Ka-25 'Hormone' helicopter as part of their standard equipment). Another benefit is increased safety on the ground; the absence of a tail rotor eliminates the major source of injuries and fatalities to ground crews and bystanders.

Grounding kits for different diameters Part of a tin-plated ripple Grounding kits / Earthing kits are composed of two main components, a clamp and a cable. The clamp will be screwed on a coaxial cable and in case of lightning strokes in the antenna installation, the voltage will be diverted over a ripple in the clamp with the combined cable and will be earthed / grounded by this way. The clamps of the grounding kits / earthing kits are composed of an ozone- and UV-resistant rubber coat with a device where the ripple can be lodged. The tin-plated ripple with a special alloying enables the bridging over big tolerances between kit and coaxial cable which is important for a best possible voltage transmission.

At its inception, the telecommunications network relied on copper to carry information. But the bandwidth of copper is limited by its physical characteristics—as the frequency of the signal increases to carry more data, more of the signal’s energy is lost as heat. Additionally, electrical signals can interfere with each other when the wires are spaced too close together, a problem known as crosstalk. In 1940, the first communication system relied on coaxial cable that operated at 3 MHz and could carry 300 telephone conversations or one television channel. By 1975, the most advanced coaxial system had a bit rate of 274 Mbit/s, but such high-frequency systems require a repeater approximately every kilometer to strengthen the signal, making such a network expensive to operate.

Scientific Atlanta Sega Channel adapter in original box complete with power adapter, coaxial adapter, and documentationAfter making the initial purchase and paying the activation fee, Genesis owners would receive an adapter that would be inserted into the cartridge slot of the console. The adapter connected the console to a cable television wire, doing so by the use of a coaxial cable output in the rear of the cartridge. Starting up a Genesis console with an active Sega Channel adapter installed would prompt for the service's main menu to be loaded, which was a process that took approximately 30 seconds. From there, gamers could access the content they wished to play and download it into their system, which could take up to a few minutes per game.

In 1980s and early 1990s coaxial cable was also used in computer networking, most prominently in Ethernet networks, where it was later in late 1990s to early 2000s replaced by UTP cables in North America and STP cables in Western Europe, both with 8P8C modular connectors. Micro coaxial cables are used in a range of consumer devices, military equipment, and also in ultra-sound scanning equipment. The most common impedances that are widely used are 50 or 52 ohms, and 75 ohms, although other impedances are available for specific applications. The 50 / 52 ohm cables are widely used for industrial and commercial two-way radio frequency applications (including radio, and telecommunications), although 75 ohms is commonly used for broadcast television and radio.

In 1994, Walter and Turner determined the free energy contributions of nearest neighbor stacking interactions within a helix-helix interface by using a model system that created a helix-helix interface between a short oligomer and a four-nucleotide overhang at the end of a hairpin stem . Their experiments confirmed that the thermodynamic contribution of base-stacking between two helical secondary structures closely mimics the thermodynamics of standard duplex formation (nearest neighbor interactions predict the thermodynamic stability of the resulting helix). The relative stability of nearest neighbor interactions can be used to predict favorable coaxial stacking based on known secondary structure. Walter and Turner found that, on average, prediction of RNA structure improved from 67% to 74% accuracy when coaxial stacking contributions were included.

A coaxial cable used to carry cable television onto subscribers' premises. A set-top box, an electronic device which cable subscribers use to connect the cable signal to their television set. Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television (also known as terrestrial television), in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television; or satellite television, in which the television signal is transmitted by a communications satellite orbiting the Earth and received by a satellite dish on the roof.

A scheme was devised to use individual "infinitesimal" passive loop antennae in each residential tower, fed by coaxial cable and carefully phased in pairs to cancel the external field. The coaxial cable had to be carefully laid out to produce the required accuracy of phasing, and splitting transformers were used to reduce power loss. The antennae were in protected ducts inside the residential buildings, and their frames were lightly built of hardboard and spruce. Since the splitting transformers were in underground ducts, they were housed in robust die-cast boxes. Despite the crudity of its construction, this system produced a strong signal of about 10mV/metre inside the residential towers, while still meeting the requirement for a negligible signal at the campus boundary.

The Ka-26 is eminently useful for crop dusting. The coaxial main rotor configuration, which makes the Ka-26 small and agile, also results in a delicate airflow pattern under the helicopter, providing a thorough, yet mild distribution of chemicals onto plants. The Ka-26 is often used to spray grape farms in Hungary, where conventional "main rotor and tail rotor" layout helicopters would damage or up-root the vine-stocks with their powerful airflow. Hungarian Kamov operators claim that coaxial rotors of the Ka-26 creates an airflow which allows pesticides to settle underneath, rather than on top of, the leaves, this means a much more effective distribution of pesticides, as most pests and parasites do not live on the top side of foliage.

But this is not applicable to thick substrates where leakages are important. In that situation, a coplanar excitation of the SIW is recommended. The drawback of the coplanar transition is the narrower bandwidth. These two kinds of transitions involve lines that are embedded in the same substrate, which is not the case for coaxial lines.

In coaxial cable the center conductor must be supported exactly in the middle of the hollow shield to prevent EM wave reflections. Finally, wires that expose voltages higher than 60 V can cause human shock and electrocution hazards. Insulating coatings help to prevent all of these problems. Some wires have a mechanical covering with no voltage rating—e.g.

Interference caused the majority of unlicensed wireless services to have much higher error rates and interruptions than equivalent wired or licensed wireless networks, such as the copper telephone network, and the coaxial cable network. This caused growth to slow, customers to cancel, and many operators to rethink their business model. There were several responses to these problems.

These form a common-mode choke which inhibits unbalanced current flow, without affecting the differential signal. This technique is equally valid for coaxial interconnects, and many camcorders have ferrite cores fitted to some of their auxiliary cables such as DC charging and external audio input, to break the high-frequency current flow if the user inadvertently creates a ground loop when connecting external equipment. RF cabling, usually coaxial, is also often equipped with a ferrite core, often a fairly large toroid, through which the cable can be wound perhaps 10 times to add a useful amount of common-mode inductance. Where no power need be transmitted, only digital data, the use of fiber optics can remove many ground loop problems, and sometimes safety problems too, but there are practical limitations.

The exhaled air goes into a corrugated coaxial exhaust hose which surrounds the low pressure hose and discharges about 60% of the way back to the first- stage to keep the bubbles away from the diver's face. Near the mouthpiece is a one-way valve to let outside water into the exhaust hose to avoid free flow if the diaphragm (at the mouth) is below the open end of the exhaust hose. The Mark I has hoses only on one side, and the Mark II has twinned low pressure hoses, each with its own coaxial exhaust hose and second stage, one assembly on each side of the diver's head, but with both second stages in the same mouthpiece housing and operated by the same diaphragm. This version has a small second stage.

In this configuration, the individual radiators within the array are often constructed of coaxial feedlines with the center conductor of one element being connected electrically to the shield of the one above, and so on in alternating phase for as many elements are specified by gain or overall length requirements. The final or 'top' element in the stack is a quarter-wave radiator connected directly to the center conductor of the element below it. This style of collinear antenna is usually housed in a fiberglass radome, to provide both support and environmental protection to the relatively fragile coaxial elements. A third type of collinear array, rarely seen outside of amateur radio VHF/UHF applications, uses half-wavelength monopole elements with phasing coils between each consecutive pair of elements to achieve the necessary phase shift.

The type of transmission line that connects two devices (chips, modules) dictates the type of signaling. Single-ended signaling is used with coaxial cables, in which one conductor totally screens the other from the environment. All screens (or shields) are combined into a single piece of material to form a common ground. Differential signaling is used with a balanced pair of conductors.

CH-46 Sea Knight Animation Tandem rotor helicopters have two large horizontal rotor assemblies mounted one in front of the other. Currently this configuration is mainly used for large cargo helicopters. Single rotor helicopters need a mechanism to neutralize the yawing movement produced by the single large rotor. This is commonly accomplished by a tail rotor, coaxial rotors, and the NOTAR systems.

A very rough approximation for the capacitor is a rating of 5 kilovolts and 1 microfarad, and the peak current ranges between 500 and 1000 amperes. The high voltage may be generated using a Marx generator. Low- impedance capacitors and low-impedance coaxial cables are required to achieve the necessary current rise rate. The flux compression generator is one alternative to capacitors.

The outer conductor is usually sheathed in a protective PVC outer jacket (A). All these have a common axis. The dimension and material of the conductors and insulation determine the cable's characteristic impedance and attenuation at various frequencies. In loudspeaker design, coaxial speakers are a loudspeaker system in which the individual driver units radiate sound from the same point or axis.

The shield should be electrically continuous to maximize effectiveness, which includes cables splices. In shielded signal cables the shield may act as the return path for the signal, or may act as screening only. High voltage power cables with solid insulation are shielded to protect the cable insulation, people and equipment. Coaxial cable is a type of shielded transmission line.

People can interact with a DTV system in various ways. One can, for example, browse the electronic program guide. Modern DTV systems sometimes use a return path providing feedback from the end user to the broadcaster. This is possible with a coaxial or fiber optic cable, a dialup modem, or Internet connection but is not possible with a standard antenna.

However, high- quality shielded twisted pair cables must be used together with elaborate connector systems for cabling. An alternative is the use of coaxial cables. Studies have shown that it is possible in spite of the simplified transfer medium dominate both emission and immunity in the high frequency range. Future high-speed video connections can be smaller, lighter and cheaper to realize.

In the electromechanical antenna switching systems employed before solid state antenna switching systems were introduced, the blending was a by-product of the way the motorized switches worked. These switches brushed a coaxial cable past 50 (or 48) antenna feeds. As the cable moved between two antenna feeds, it would couple signal into both. But blending accentuates another complication of a DVOR.

RockNet by Riedel Communications, uses Cat-5 cabling. Hydra2 by Calrec uses Cat-5e cabling or fiber through SFP transceivers. MADI uses 75-ohm coaxial cable with BNC connectors or optical fibre to carry up to 64 channels of digital audio in a point-to-point connection. It is most similar in design to AES3, which can carry only two channels.

A cable television system is an example of frequency- division multiplexing. Many television programs are carried simultaneously on the same coaxial cable by sending each at a different frequency. Multiple layers of multiplexing may ultimately be performed upon a given input signal. For example, in the public switched telephone network, many telephone calls are sent over shared trunk lines by time-division multiplexing.

Adapter between a female BNC connector and a pair of banana plugs A number of widely used plugs are based on combining two or more banana plugs in a common plastic housing and other features for ease of use and to prevent accidental insertion in other such plugs. Many of these plugs are derived from the "double banana" plug consisting simply of two banana plugs spaced inch (about 19 mm) apart (measured from center to center of each individual plug). The inch spacing originated on General Radio test equipment during the 1920s, and their type 274-M dual-plug is a notable example from that era. The housing may allow the connection of individual wires, a permanently attached coaxial cable providing both signal and ground, or a coaxial connector such as the BNC connector shown in the photo.

The term propfan was created during this time. One of the earliest engines that resembled the propfan concept was the Metrovick F.5, which featured twin contra-rotating fans—14 blades in the fore (front) fan and 12 blades in the aft (back) fan—at the rear of the engine and was first run in 1946. The blades, however, were mostly unswept. There were other contra-rotating propeller engines that featured on common aircraft, such as the four powerful Kuznetsov NK-12 engines (each powering its own set of coaxial contra-rotating propellers) on the Soviet Union's Tupolev Tu-95 Bear high-speed military bomber and Antonov An-22 military transport aircraft, and the Armstrong Siddeley Double Mamba (ASMD) engines (both connected to a lone set of coaxial contra-rotating propellers) on the British Fairey Gannet anti- submarine aircraft.

When coaxial cables were introduced as submarine cables, a new issue with cable-laying was encountered. These cables had periodic repeaters inline with the cable and powered through it. Repeaters overcame significant transmission problems on submarine cables. The difficulty with laying repeaters is that there is a bulge where they are spliced in to the cable and this causes problems passing through the sheave.

Coaxial cable, one example of a jacketed wire. Overjacketing extrusion is a coating process, in which individual bare wires or bundles of pre-coated wires are coated with a layer of insulating polymer. A wide variety of materials may be used, depending on the specific application. For many applications, such as insulated cables, the polymer should be a good insulator, flexible, and wear resistant.

Admission control requires devices to receive permission before establishing new network connections. If the new connection risks creating congestion, permission can be denied. One example of this is the use of Contention-Free Transmission Opportunities (CFTXOPs) in the ITU-T G.hn standard, which provides high-speed (up to 1 Gbit/s) local area networking over varying wires (power lines, phone lines and coaxial cables).

For AC-operated devices (e.g. coaxial cable, loudspeakers), there may even be two power ratings, a maximum (peak) power rating and an average power rating. For such devices, the peak power rating usually specifies the low frequency or pulse energy, while the average power rating limits high-frequency operation. Average power calculation rating depends on some assumptions how the device is going to be used.

ZiU-5 is equipped with motor-generator for transformation of the input DC high voltage (550V) to low service DC voltage of 24V. This transformation is quite simple - 550V electric motor has coaxial connection with 24V electric generator. However, the drawback of this simplicity is a constant noise of this device. However good oilment and centring procedures can reduce this noise to tolerant level.

China Central Television also contracted with several foreign broadcasters for entertainment programs. Between 1982 and 1985, six United States television companies signed agreements to provide American programs to China. Since the late 1950s, people in Pearl River Delta began to receive channels from Hong Kong with Coaxial cable (1957-1973) and Yagi-Uda antenna (1967 onwards). Hong Kong channels were considered more entertaining and had Cantonese shows.

Tandem rotor helicopters, however, use counter- rotating rotors, with each cancelling out the other's torque. Therefore, all of the power from the engines can be used for lift, whereas a single rotor helicopter uses some of the engine power to counter the torque. An alternative is to mount two rotors in a coaxial configuration. The first successful tandem rotor helicopter was built by Nicolas Florine in 1927.

Deployment of BPL has illustrated a number of fundamental challenges, the primary one being that power lines are inherently a very noisy environment. Every time a device turns on or off, it introduces a pop or click into the line. Switching power supplies often introduce noisy harmonics into the line. And unlike coaxial cable or twisted- pair, the wiring has no inherent noise rejection.

AppleTalk protocols also came to run over Ethernet (first coaxial and then twisted pair) and Token Ring physical layers, labeled by Apple as EtherTalk and TokenTalk, respectively. EtherTalk gradually became the dominant implementation method for AppleTalk as Ethernet became generally popular in the PC industry throughout the 1990s. Besides AppleTalk and TCP/IP, any Ethernet network could also simultaneously carry other protocols such as DECnet and IPX.

RF transformers sometimes used a third coil (called a tickler winding) to inject feedback into an earlier (detector) stage in antique regenerative radio receivers. In RF and microwave systems, a quarter-wave impedance transformer provides a way of matching impedances between circuits over a limited range of frequencies, using only a length of transmission line. The line may be coaxial cable, waveguide, stripline, or microstrip.

The number of cables is not limited by the standard. Some recent CoaXPress cameras and frame grabbers use 8 coaxial cables providing a maximum image data rate of about 4.8 GB/s. The older Camera Link standard can only carry up to 850 MB/s. A low speed uplink, operating at up to 41.6 Mbit/s is available to control the 'device' or for triggering.
|
|
A CoaXPress 'host' can supply 24 V over the coaxial cable up to 13 W per cable. The CoaXPress standard requires that both the 'device' and the 'host' support GenICam, a standardized generic programming interface. Other than Camera Link that is built upon pure LVDS with no transport layer, CoaXPress transmits data in packets (cf. network packet) using 8b/10b encoding and provides CRC.

The cable should be grounded at one end. Grounding the terminators at both may produce a ground loop and can cause network outages or data corruption when swells of electricity traverse the coaxial cabling's outer shield. When wiring a 10BASE2 network, special care has to be taken to ensure that cables are properly connected to all T-connectors. Bad contacts or shorts are especially difficult to diagnose.

The world's first coaxial cable was laid between London and Birmingham in 1936 to give 40 channels for telephone traffic. and brought into use in 1938, later extended to Manchester in 1940. The Baskerville font named after the inventor of typefaces Alexander Parkes invented the first man- made plastic (thermoplastic) in Birmingham in 1856. Arthur Leslie Large of Birmingham is credited with inventing the kettle in 1922.

A type of transmission line called a cage line, used for high power, low frequency applications. It functions similarly to a large coaxial cable. This example is the antenna feed line for a longwave radio transmitter in Poland, which operates at a frequency of 225 kHz and a power of 1200 kW. A microstrip circuit uses a thin flat conductor which is parallel to a ground plane.

A physical medium in data communications is the transmission path over which a signal propagates. Many different types of transmission media are used as communications channel. In many forms of communications, communication is in the form of electromagnetic waves. With guided transmission media, the waves are guided along a physical path; examples of guided media include phone lines, twisted pair cables, coaxial cables, and optical fibers.

The best coaxial cable impedances in high-power, high-voltage, and low-attenuation applications were experimentally determined at Bell Laboratories in 1929 to be 30, 60, and 77 Ω, respectively. For a coaxial cable with air dielectric and a shield of a given inner diameter, the attenuation is minimized by choosing the diameter of the inner conductor to give a characteristic impedance of 76.7 Ω. When more common dielectrics are considered, the best-loss impedance drops down to a value between 52–64 Ω. Maximum power handling is achieved at 30 Ω. The approximate impedance required to match a centre-fed dipole antenna in free space (i.e., a dipole without ground reflections) is 73 Ω, so 75 Ω coax was commonly used for connecting shortwave antennas to receivers. These typically involve such low levels of RF power that power-handling and high-voltage breakdown characteristics are unimportant when compared to attenuation.

Espeli: 378 Coaxial was tested with the construction of a line from Oslo which from completed to Gjøvik in 1953 and to Bergen in 1957. The military opened a relay between Eastern Norway and Bergen in 1954 with 24 telephone lines. However, the Telegraphy Administration initially remained skeptical to the technology. In the end relays were regarded as the only realistic approach, although it would still incur large investments.

The SLA then deployed four M9 Half-tracks equipped with Browning HB heavy machine guns, which they used to harass UNIFIL convoys. Two days later, Irish AML-90s counterattacked and retook the village. One half-track was immobilised, and a second destroyed after receiving a direct hit from a 90 mm shell. A third was abandoned when its Browning was disabled by warning fire from an AML's coaxial machine gun.

Early Ethernet (10BASE-5 and 10BASE-2) used coaxial cable. Shielded twisted pair was used in IBM's Token Ring LAN implementation. In 1984, StarLAN showed the potential of simple unshielded twisted pair by using category 3 cable—the same cable used for telephone systems. This led to the development of 10BASE-T (and its twisted- pair successors) and structured cabling which is still the basis of most commercial LANs today.

Developed by MotoCzysz for their C1 and awarded United States Patent 7111700 on September 26, 2006. Defined as a motorcycle or bicycle front end having coaxial steering and suspension components, and having telescopic forks. Swing weight of the forks is dramatically reduced by removing their suspension components to the central location, coaxially within the steering tube. Ride height can be adjusted without loosening the forks in the triple clamps.

Its design avoided the need to add oil to the escapement because the mechanism operated with very low friction. Traditional escapements had to use lubricants but this eventually caused problems with accuracy as oil thickened over time. However, the coaxial escapement used radial friction instead of sliding friction, making lubricants theoretically unnecessary. In practice a small mount of lubrication is used on the impulse and locking surfaces of the pallet stones.

Triaxial BNC connector. Newer variants have three locking lugs rather than the two used here to prevent accidental interconnection with regular BNC connectors. Triaxial cable, often referred to as triax for short, is a type of electrical cable similar to coaxial cable, but with the addition of an extra layer of insulation and a second conducting sheath. It provides greater bandwidth and rejection of interference than coax, but is more expensive.

Although a highly ingenious escapement design, the Daniels coaxial nevertheless still needs lubrication to the lever pallet pivots. In addition, because of its geometry the impulse wheel can only have a limited number of teeth, thus it is necessary to have an extra wheel and pinion in the wheel train the pivots of which also need lubricating. Therefore, the advantages of this escapement over the lever are of an uncertain value.

The push–pull connector is a type of cable interconnect that provides a strong locking mechanism that is only released by squeezing the connector body, thus preventing accidental disconnects. The connector is cylindrical, enabling a wide range of body styles and configurations such as low or high voltage multipin, coaxial, triaxial, fluid and gas. It was invented by Swiss manufacturer LEMO. Other manufacturing companies include Fischer Connectors and Switchcraft.

"Hyperchannel" referred to an early, proprietary LAN protocol. The earlier, "A-series" Hyperchannel "adapter" had a device interface and a trunk (LAN) interface, which could drive up to four coaxial trunks, each carrying 50 Mbit/s. Intercommunication between adapters was always across the trunk. The A-series adapter had a processor made from discrete, high-speed ECL components, with an 8K program memory and a 4K or an 8K data memory.

Electric field lines for this [TM] mode have a longitudinal component and require line lengths of a half-wavelength or longer. Coaxial cable may be viewed as a type of waveguide. Power is transmitted through the radial electric field and the circumferential magnetic field in the TEM00 transverse mode. This is the dominant mode from zero frequency (DC) to an upper limit determined by the electrical dimensions of the cable.

Despite being shielded, interference can occur on coaxial cable lines. Susceptibility to interference has little relationship to broad cable type designations (e.g. RG-59, RG-6) but is strongly related to the composition and configuration of the cable's shielding. For cable television, with frequencies extending well into the UHF range, a foil shield is normally provided, and will provide total coverage as well as high effectiveness against high- frequency interference.

It can carry 40 rounds for the main armament, with 22 ready to use in the autoloader. In case the autoloader is no longer intact, manual loading is possible at the cost of a substantially longer reload time. A coaxial 7.62 mm PKT machine gun mounted to the left side of the main armament serves as the secondary armament of the 2S25; equipped with one tape of 2000 rounds.

The Black Knight is a prototype unmanned ground combat vehicle (UGCV) designed by BAE Systems. It weighs approximately 12 tons and is deployable from a C-130; thus, the Black Knight can be airlifted by military transport aircraft. Similar in appearance to a tank, it is armed with a turret-mounted 30 mm gun and a 7.62 mm coaxial machine gun. The vehicle is fitted with a 300-horsepower Caterpillar Inc.

Long undersea or underground high-voltage cables have a high electrical capacitance compared with overhead transmission lines, since the live conductors within the cable are surrounded by a relatively thin layer of insulation (the dielectric), and a metal sheath. The geometry is that of a long coaxial capacitor. The total capacitance increases with the length of the cable. This capacitance is in a parallel circuit with the load.

Thicknet coaxial cabling is used with Ethernet 10BASE5 networks, has a maximum cable length of 500 meters and transmission speeds of 10 Mbit/s. It's expensive and not commonly used, though it was originally used to directly connect computers. The computer is connected to the transceiver at the cable from the attachment unit interface of its network card using a drop cable. Maximum thicknet nodes are 100 on a segment.

In most applications, there is no need for high- pressure hydraulics. Other advantages shared with similar CVT designs include that the input and output shafts may be either in-line, offset, or in a U configuration (input and output both coaxial and coplanar), making the transmission simple, small, light and easy to package. Fallbrook claims the transmission control is stable, linear and does not require a major control system development effort.

Cables for connection of computer peripherals often have a ferrite bead. The cable can be used to increase the inductance also repeatedly passed through a ferrite core. Ferrite sheath current filters can only work effectively if a common-mode signal can flow on a line. This is generally the case when a cable bundle or a coaxial cable has a ground connection at both ends to the grounded equipment.

|
The HFCT method needs to be used because of the small magnitude and short duration of these PD events. The HFCT method is done while the component being tested stays energized and loaded. It is completely non-intrusive. Another method of measuring these currents is to put a small current-measuring resistor in series with the sample and then view the generated voltage on an oscilloscope via a matched coaxial cable.

The propeller screws were coaxial contra- rotating double screws, with 4 propeller blades each. Each screw was wrought from a cubical mass of SK chromium-molybdenum alloy steel into a bold cross shape and punched through the centre. Hammering punches of 1tons and 3tons shaped the 4 blades. The propeller sections were compactly designed to allow the front screw and the rear screw to be only 5 mm apart.

1960.1124668 this circuit finds wide use in radio frequency communication systems utilizing multiple channels since the high degree of isolation between the output ports prevents crosstalk between the individual channels. It uses quarter wave transformers, which can be easily fabricated as quarter wave lines on printed circuit boards. It is also possible to use other forms of transmission line (e.g. coaxial cable) or lumped circuit elements (inductors and capacitors).

The studio quiet 16mm Cinema Products GSMO was introduced in the mid-1970s. It had quick loading coaxial magazines, an 'in camera' light meter viewable in the eyepiece and an on-camera battery. The GSMO stood for "gun sight man operated". (Cinema Products would often develop products under government contracts, then adapt them for industry wide marketing.) The GSMO was popular among documentarians and low-budget independent producers.

For the firing of the gun and coaxial machine gun at night, the tank was equipped with two special projector-type headlamps, and a mask placed on the gun. Subsequently, these lights were retrofitted to earlier models of the tank. Improvements were also made to the drive wheels, caterpillar tracks and gearbox by 1938. In parallel with the main modification, 154 BT-7A artillery tanks were produced between 1936 and 1938.

In 2013, a group from the University of Tokyo developed cell laden fibers up to a meter in length and on the order of 100 µm in size.Hiroaki Onoe, Teru Okitsu, and Akane et al. Itou. Metre-long cell-laden microfibres exhibit tissue morphologies and functions. Nature Materials, 12(6):584 – 590, 2013 These fibers were created using a microfluidic device that forms a double coaxial laminar flow.

An RF admittance level sensor uses a rod probe and RF source to measure the change in admittance. The probe is driven through a shielded coaxial cable to eliminate the effects of changing cable capacitance to ground. When the level changes around the probe, a corresponding change in the dielectric is observed. This changes the admittance of this imperfect capacitor and this change is measured to detect change of level.

Senstar started in 1981 as a spin-off from the Computing Devices Division of Control Data Canada (CDC). Its founders created Sentrax, the world's first ported coaxial cable sensor. Early adopters of the technology included the U.S. military as well as the Correctional Service of Canada, who installed the buried sensor system at its correctional facilities throughout Canada. In 1994 Senstar was acquired by the Dornier Group of Daimler Benz.

Broadband cable access tends to service fewer business customers because existing television cable networks tend to service residential buildings and commercial buildings do not always include wiring for coaxial cable networks. p 323. In addition, because broadband cable subscribers share the same local line, communications may be intercepted by neighboring subscribers. Cable networks regularly provide encryption schemes for data traveling to and from customers, but these schemes may be thwarted.

The helicopter was developed for ferrying and anti-submarine warfare. Design work began in 1969 and the first prototype flew in 1973. It was intended to replace the decade- old Kamov Ka-25, and is similar in appearance to its predecessor due to the requirements of fitting in the same hangar space. Like other Kamov military helicopters it has coaxial rotors, removing the need for a tail rotor.

The low pressure turbine (LPT) is provided by Industria de Turbo Propulsores (ITP), and it is derived from the LPT of the Rolls-Royce BR715 regional turbofan. This free-power turbine drives the propeller through a third coaxial shaft and a reduction gearbox. The Avio-produced gearbox has a maximum power output of about . Reduction occurs in two stages: a first-stage offset design, followed by a second-stage planetary system.

Coaxial rotors are two rotors mounted one above the other on the same axis. Intermeshing rotors are two rotors mounted close to each other at a sufficient angle to let the rotors intermesh over the top of the aircraft. Another configuration—found on tiltrotors and some early helicopters—is called transverse rotors, where a pair of rotors are mounted at each end of a wing-type structure or outrigger.
|
|
The design was intended to be a simplified helicopter. Constructed by two brothers with no prior aeronautical experience or skills it employed a unique coaxial, counter-rotating, fixed pitch rotor system with no collective control, but employed a rudder. To account for the fact that the aircraft could not autorotate after a power failure, it was equipped with two engines and could hover on either one. A ballistic parachute was optional.

Lee Cook, along with Houston banker Jesse Jones and William T. Carter, founded Phonoscope in 1953. Cook reportedly outlived his co- founders. Phonoscope established a two-way videotelephony system in 1962 for Galveston Independent School District, connecting eight elementary schools to the district's administration building using coaxial cable. In 1989, Phonoscope completed a large scale fiber optic ring for Ethernet transport in Houston, encompassing all the major central business districts.

However, some early implementations used heavier coaxial cables and some recent implementations (especially high-speed ones) use optical fibers.Stallings, pp. 514–16. When optic fibers are used, the distinction must be made between multimode fibers and single-mode fibers. Multimode fibers can be thought of as thicker optical fibers that are cheaper to manufacture devices for, but that suffers from less usable bandwidth and worse attenuation—implying poorer long-distance performance.

De Bothezat's new helicopter was a coaxial design, with the engine mounted between two rotors. The first machine, SV-2, was built and tested on Roosevelt Field in 1938; after the tests de Bothezat and Sergievsky rebuilt it into a heavier SV-5. However de Bothezat, who was also designing a one-man "personal helicopter" for infantrymen,One-Man Helicopters Give Soldiers Wings. Popular Science, March 1940 p. 129.

However, the gunner is poorly protected and at risk of injury in the event of vehicle rollover. During the Vietnam War, M113 gunners often suffered heavy casualties. Enclosed vehicles are equipped with turrets that allow the crew to operate the weapons system while protected by the vehicle's armour. The Soviet BTR-60 has an enclosed turret mounted with a KPV heavy machine gun with a PKT coaxial machine gun.

This inexpensive Vivaldi antenna is etched upon a printed circuit board and fed with a soldered-on coaxial cable and SMA connector. Advantages of Vivaldi antennas are their broadband characteristics (suitable for ultra-wideband signals ), their easy manufacturing process using common methods for PCB production, and their easy impedance matching to the feeding line using microstrip line modeling methods. The MWEE collection of EM simulation benchmarks includes a Vivaldi antenna.

Traditional boats use an inboard motor powering a propeller through a propeller shaft complete with bearings and seals. Often a gear reduction is incorporated in order to be able to use a larger more efficient propeller. This can be a traditional gear box, coaxial planetary gears or a transmission with belts or chains. Because of the inevitable loss associated with gearing, many drives eliminate it by using slow high-torque motors.

The cable node located in the field in-turn reverses the optical light from the hub and changes the signals back to RF over coaxial cable. This is called a "forward" path (download). The inverse happens on the upload or "return" path as customers transmit data back to a hub. Cable nodes were initially intended to reduce amplifier cascade and improve signal quality to subscribers distant from a hub.

Eventually the decision was taken to install a 6 tube coaxial cable. While this provided more capacity than was necessary at the time, it also allowed for the transmission of television signals along the route. The associated carrier equipment (e.g. the active electronics) was to have sufficient capacity for the first 5 years with facilities for readily increasing the number of channels to meet demand for the next 20 years.

Coaxial cable, one example of a jacketed and insulated wire Electrical wires are usually covered with insulating materials, such as plastic, rubber-like polymers, or varnish. Insulating and jacketing of wires and cables is nowadays done by passing them through an extruder. Formerly, materials used for insulation included treated cloth or paper and various oil-based products. Since the mid-1960s, plastic and polymers exhibiting properties similar to rubber have predominated.

These modes are classified into two groups, transverse electric (TE) and transverse magnetic (TM) waveguide modes. When more than one mode can exist, bends and other irregularities in the cable geometry can cause power to be transferred from one mode to another. The most common use for coaxial cables is for television and other signals with bandwidth of multiple megahertz. In the middle 20th century they carried long distance telephone connections.

Microstrip can be made by having a strip of copper on one side of a printed circuit board (PCB) or ceramic substrate while the other side is a continuous ground plane. The width of the strip, the thickness of the insulating layer (PCB or ceramic) and the dielectric constant of the insulating layer determine the characteristic impedance. Microstrip is an open structure whereas coaxial cable is a closed structure.

T-4 and T-5 used coaxial cables, similar to the old L-carriers used by AT&T; Long Lines. TD microwave radio relay systems were also fitted with high rate modems to allow them to carry a DS1 signal in a portion of their FM spectrum that had too poor quality for voice service. Later they carried DS3 and DS4 signals. During the 1980s companies such as RLH Industries, Inc.

A T-62 armed with the DShK 1938/46 antiaircraft heavy machine gun The armament consists of the 115 mm U-5TS "Molot" (2A20) Rapira smoothbore tank gun with a two-axis "Meteor" stabiliser and 7.62 mm PKT coaxial general-purpose machine gun mounted on the right of the main gun. The 12.7 mm DShK 1938/46 antiaircraft heavy machine gun is mounted on the loader's hatch. It was optional until 1972 when all newly built tanks were fitted with the AA heavy machine gun. The tank carries 40 rounds for the main gun (although only 4 are placed in the turret, the rest are stored in the back of the fighting compartment and in the front of the hull, to the right of the driver) and 2500 rounds for the coaxial machine gun. All of the vehicle's armament is mounted in or on the round cast egg-shaped turret from the Ob'yekt 140 prototype main battle tank, mounted over the third pair of road wheels.

A virtual LNB with four electrical outputs for four tuners The complete spectrum of Ku-band satellite reception stretches from 10.70 GHz-12.75 GHz across two signal polarisations, or a bandwidth of about 4000 MHz. This cannot be carried on a single coaxial cable and so in a conventional satellite reception system, just one of four sub-bands (received in vertical and horizontal polarization, and high and low frequency,) is sent from the antenna to the indoor receiver as 0.95 GHz-2.15 GHz IF. Which sub- band is required is signalled from the receiver to the antenna’s LNB by a 13/18V and 0/22 kHz tone on the LNB supply sent up the same coaxial cable. In a single antenna distribution system, special quattro LNB supplies all four sub-bands at once, from four outputs and these are supplied as required to each of the multiple outlets connected to an IF multiswitch.Bains, Geoff.

These tubes are typically coaxial, with two separate channels and two separate openings. They incorporate an endotracheal lumen which terminates in the trachea and an endobronchial lumen, the distal tip of which is positioned 1–2 cm into the right or left mainstem bronchus. There is also the Univent tube, which has a single tracheal lumen and an integrated endobronchial blocker. These tubes enable one to ventilate both lungs, or either lung independently.

The LAV III is fitted with a two-man turret, armed with the M242 Bushmaster 25 mm caliber chain gun and a coaxial 7.62-mm machine gun. One more 5.56 mm or 7.62 mm machine guns is positioned on top of the turret. The LAV III also has eight 76-mm grenade launchers in two clusters of four launchers positioned on each side of the turret. The grenade launchers are intended for smoke grenades.

However, there is no need for more complex circuitry, as there is with filters, due to the simplicity of the frequency response required. Circuits are required to be balanced or unbalanced depending on the geometry of the transmission lines they are to be used with. For radio frequency applications, the format is often unbalanced, such as coaxial. For audio and telecommunications, balanced circuits are usually required, such as with the twisted pair format.

Armament consists of the 30mm 2A42 multi-purpose autocannon and the 7.62mm PKT coaxial machine gun with a 2-plane stabilization system. The weapons are controlled through the gunner's control panel. It is possible to integrate the anti-tank guided missile (ATGM), or antiaircraft guided missile (AAGM), depending on the customer's requirements. The turret is equipped with the modernized BPK-2-42 periscopic sight with a swing of the mirror from −5° up to +60°.

It was transversely mounted in unit with the transaxle transmission assembly, which was below and to the rear of the engine's sump. All models used a fully synchromesh 5-speed "dog-leg" manual gearbox and a clutch-type limited slip differential. Suspension was all-independent, comprising double wishbones, coaxial coil springs and hydraulic dampers, and anti-roll bars on both axles; four wheel vented disc brakes were also fitted. Steering was unassisted rack and pinion.

M3 light tanks in the background Side view By October, the US developers reached the same conclusion as their European counterparts. The armament was changed to a single vertically stabilized 3-inch (76.2 mm) gun and a coaxial 37 mm gun in a single three-man turret with both manual and electric traverse. The turret had a commander's cupola identical to that of the M3 Medium Tank. Additional armament consisted of two .

The goal of the development was to produce a large, low-cost, easy-to-manufacture booster engine. The design used a single element coaxial pintle injector, a robust type of injector. It also used ablative cooling of the combustion chamber and nozzle instead of the more costly to manufacture regenerative cooling. The use of the pintle injector allows the engine thrust to be widely throttleable, as was the case for the lunar module descent engine.

The Kurganets-25 IFV features the Bumerang-BM remote control turret with its 2A42 30 mm autocannon, a 7.62 mm coaxial PKT machine gun and a bank of two Kornet-EM anti-tank guided missiles on either side. The Kurganets-25 APC variant has a 12.7 mm MG RWS instead of the Bumerang-BM turret. An SPAAG version with a 57 mm autocannon and a Kurganets-25 SPG with a 125 mm are planned.

Close-up of a Czech BPzV-1's turret, 2 July 2005. Note the ATGM launcher for the 9M14M Malyutka-M A coaxial 7.62 mm PKT machine gun is mounted to the right of the main armament for which the BMP-1 carries 2,000 rounds in belts of 250. They are stowed in two boxes under the main gun. The machine gun has a rate of fire of around 800 rounds a minute.

The 2A28 "Grom" gun and PKT coaxial machine gun cannot be accurately fired while the vehicle is moving over rough ground. This means that the BMP-1's main armament is less capable than modern stabilised autocannons, which can be fired accurately while moving. The BMP-1 is unable to engage tanks and APCs using the 2A28 "Grom" gun from hull-down positions due to its limited depression, making it vulnerable to enemy fire.Global Security.

7 July 2000. Although most earlier designs used more than one main rotors, the configuration of a single main rotor (monocopter) accompanied by a vertical anti-torque tail rotor has become the most common helicopter configuration. Twin-main rotor helicopters (bicopters), in either tandem or transverse rotors configurations, are also in use due to their greater payload capacity than the monorotor design. Coaxial- rotor helicopters, tiltrotor aircraft, and compound helicopters are all flying today.

His writings on his experiments and models would become influential on future aviation pioneers. Alphonse Pénaud would later develop coaxial rotor model helicopter toys in 1870, also powered by rubber bands. One of these toys, given as a gift by their father, would inspire the Wright brothers to pursue the dream of flight. In 1861, the word "helicopter" was coined by Gustave de Ponton d'Amécourt, a French inventor who demonstrated a small steam-powered model.

All subsystems are attached to the combustion chamber and gimbal is achieved by rotating the whole engine on two orthogonal planes with two independent actuators. The injector plate uses coaxial injectors, some of which are extended to create baffles that prevent high frequency instabilities. The titanium fuel turbopump uses a two-stage pump with inducer and is actuated by a two-stage axial turbine. It rotates at 35,000 rpm and supplies a discharge pressure of .

A backronym has been mistakenly applied to it: British Naval Connector. Another common incorrectly attributed origin is Berkeley Nucleonics Corporation. The basis for the development of the BNC connector was largely the work of Octavio M. Salati, a graduate of the Moore School of Electrical Engineering of the University of Pennsylvania. In 1945, while working at Hazeltine Electronics Corporation, he filed a patent for a connector for coaxial cables that would minimize wave reflection/loss.

The plane was conceived as a fast light bomber and reconnaissance plane. To obtain high speed and good aerodynamics, it was powered by two M-103 inline engines in tandem in a fuselage nose, driving two contra-rotating coaxial three-blade propellers. The design had quite unusual look, with long fuselage nose and a crew cab moved rearwards, towards double tailfin. Wings had a fighter-like form and their span was rather short.

Coaxial design helps to further reduce low-frequency magnetic transmission and pickup. In this design the foil or mesh shield has a circular cross section and the inner conductor is exactly at its center. This causes the voltages induced by a magnetic field between the shield and the core conductor to consist of two nearly equal magnitudes which cancel each other. A twisted pair has two wires of a cable twisted around each other.

TAT-6 was the sixth transatlantic telephone cable. It was in operation from 1976 to 1994, with a bandwidth of 12MHz (4,000 telephone circuits) between Green Hill (United States) and Saint-Hilaire-de-Riez, Vendée, (France). Known as the SG coaxial cable system, designed by Bell Labs, the cable is with repeater spacing of . The deep sea portion, some in length, was laid by the Cable Ship Long Lines, owned by AT&T.

The combustion products expand axially forward through the two-stage (single-stage on early engines) high-pressure turbine section, which is connected to the compressor via the HP shaft. The combustion products continue to expand through the two-stage power turbine which generates shaft horsepower for the aircraft. A coaxial stub shaft connects the power turbine to a compact reduction gearbox, located inboard, between the centrifugal compressor and the exhaust/power turbine system.

In some applications, cables going from the repeater and duplexers must be tuned to mitigate these issues. In dual antenna systems, there are two antennas and two lengths of coaxial cable running from the transmitter and receiver. Usually, triple shield coax and or low loss Heliax are used to keep the two systems isolated. Two antenna systems are usually used if tower space is not limited, or space to build an array is available.

A large control surface, the Digidesign Profile. This surface connects to the mixing hardware by way of four coaxial cables. In the domain of digital audio, a control surface is a human interface device (HID) which allows the user to control a digital audio workstation or other digital audio application. Generally, a control surface will contain one or more controls that can be assigned to parameters in the software, allowing tactile control of the software.

The procedure can be performed with general anesthesia or under conscious sedation in an angiographic room. A system of coaxial catheters is pushed inside the arterial circulation, usually through a percutaneous access to the right femoral artery. A microcatheter is finally positioned beyond the occluded segment and a stent-retriever is deployed to catch the thrombus; finally, the stent is pulled out from the artery, usually under continuous aspiration in the larger catheters.

The 160 meter sloper system at K3LR in The ARRL Antenna Compendium Vol. 4 The angle of the slope is usually between 45°-60° and the lower end of the wire is at least wavelength above the electrical ground. A sloper is typically fed with a coaxial cable in the center, at the top of the center support mast. At least of the wavelength of feedline must be at 90° angle to the antenna.

For its construction, it took advantage of several pre-existing buildings, which were all given a common "wrapper". Thus it lacks axial and coaxial axis symmetry. It is built according to its own historical and eclectic style of much of the nineteenth century; using in the facades Neo-Mudéjar and Italian Classicism styles. In the decoration of the interior rooms, there are used a multitude of historicist styles (Neo-Mudéjar, Rococo, Chinoiserie, Egyptian, English, etc.).

The planned main armament was a 47 mm SA35 gun gun. 176 rounds were stowed in the fighting compartment in rotary and tilting magazines in order to be reached quickly. Secondary armament included two 7.5mm machine guns; one coaxial machine gun and one anti-aircraft defence machine gun mounted on a retractable ball mount behind the turret. Up to 30 magazines were stored in a large belt mechanism to the right of the driver.

G.hn is a specification for home networking with data rates up to 2 Gbit/s and operation over four types of legacy wires: telephone wiring, coaxial cables, power lines and plastic optical fiber. A single G.hn semiconductor device is able to network over any of the supported home wire types. Some benefits of a multi-wire standard are lower equipment development costs and lower deployment costs for service providers (by allowing customer self-install).

Fiber connections have minimum cable lengths due to level requirements on received signals. Fiber ports designed for long-haul wavelengths require a signal attenuator if used within a building. 10BASE2 installations, running on RG-58 coaxial cable, require a minimum of 0.5 m between stations tapped into the network cable, this is to minimize reflections. 10BASE-T, 100BASE-T, and 1000BASE-T installations running on twisted pair cable use a star topology.

The antennas were mounted directly to the side of the cabin, rotating with it. This had the significant advantage that the coaxial cables between the antennas and the equipment inside were very short. The first example was sited at the Lydden Spout Battery in July 1941. Unofficially referred to as Type NT271X, it was later given the official name Radar, Coast Defense, Number 1 Mark 4, or CD No.1 Mk.4 for short.

Energy would radiate from the coax itself, affecting the radiation pattern of the antenna. With sufficient power this could be a hazard to people near the cable. A properly placed and properly sized balun can prevent common mode radiation in coax. An isolating transformer or blocking capacitor can be used to couple a coaxial cable to equipment, where it is desirable to pass radio- frequency signals but to block direct current or low-frequency power.

The Trent 1000 is a high bypass turbofan with three independent, coaxial shafts and a single annular combustor with 18 spray nozzles. The Low Pressure shaft with a swept-bladed, fan is powered by six axial turbines. The Intermediate Pressure spool with 8 axial compressors is turned by a single turbine stage. The six-stage High Pressure Compressor is driven by a single turbine stage, turning in the opposite direction of the two others shafts.

For example, a standard three-conductor mains cable is never referred to as multicore, but a cable comprising four coaxial cables in a single sheath would be considered multicore. Confusingly, the term multicore is occasionally used to refer to the number of individual conductors rather than the number of connections, especially in Europe. A cable with multiple conductors, but not a multicore cable, is usually called a multi-conductor or multi-wire cable.

1965 Giulietta Spider Veloce engine The Alfa Romeo Giulietta used unibody construction and a front-engine, rear-wheel-drive layout. Front suspension was by control arms, with coaxial coil springs and hydraulic dampers. At the rear there was a solid axle on coil springs and hydraulic dampers. The axle was located by a longitudinal link on each side, and by a wishbone-shaped arm linking the top of the aluminium differential housing to the chassis.

The most widely used types of feed line are coaxial cable, twin-lead, ladder line, and at microwave frequencies, waveguide. Particularly with a transmitting antenna, the feed line is a critical component that must be adjusted to work correctly with the antenna and transmitter. Each type of transmission line has a specific characteristic impedance. This must be matched to the impedance of the antenna and the transmitter, to transfer power efficiently to the antenna.

X band 10.15 to 10.7 GHz segment is used for terrestrial broadband in many countries, such as Brazil, Mexico, Saudi Arabia, Denmark, Ukraine, Spain and Ireland. Alvarion, CBNL, CableFree and Ogier make systems for this, though each has a proprietary airlink. The Ogier system is a full duplex Transverter used for DOCSIS over microwave. The home / Business CPE has a single coaxial cable with a power adapter connecting to an ordinary cable modem.

Conversion to the "chin" design was gradual, and Panthers continued to be produced to the end of the war with the rounded gun mantlet.Jentz 1995, p. 96 The Ausf A model introduced a new cast armour commander's cupola, replacing the forged cupola. It featured a steel hoop to which a third MG 34 or either the coaxial or the bow machine gun could be mounted for use in the anti-aircraft role.

The design is still used to this day by some bottlers. Most modern-day two- liter bottles are one piece of PET (polyethylene terephthalate) with a base that is molded with a radial corrugation to provide strength for the bottom and the ability to stand upright. Most early two-liters had a separate opaque base glued to the hemispherical bottom of the clear PET flask. This base had a coaxial corrugation and drain holes.

The two most popular types of coaxial cabling are used with Ethernet networks. Thinnet is used on Ethernet 10BASE2 networks and is the thinner and more flexible of the two. Unlike a thicknet, it uses a Bayonet Niell-Concelman (BNC) on each end to connect to computers. Thinnet is part of the RG-58 family of cable with a maximum cable length of 185 meters and transmission speeds of 10 Mbit/s.

However, there is no need for more complex circuitry, as there is with filters, due to the simplicity of the frequency response required. Circuits are required to be balanced or unbalanced depending on the geometry of the transmission lines they are to be used with. For radio frequency applications, the format is often unbalanced, such as coaxial. For audio and telecommunications, balanced circuits are usually required, such as with the twisted pair format.

Along with standard tanks a flamethrower-armed version was designed (designated TO-55 (Ob'yekt 482)), which was produced until 1962. It was fitted with 460 litre tanks filled with flammable liquid instead of the frontal hull fuel tanks. The flamethrower replaced the coaxial machine gun. This was a much better way to mount a flamethrower than in the experimental Ob'yekt 483, based on the T-54 tank, where the flamethrower replaced the main gun.

The high frequencies arrived at the listener's ear slightly later than the low frequencies. One drawback of the design is the production line difficulty in mating the two drivers, and in replacing or reconing the woofer. Another drawback is that the low frequencies tend to modulate the high frequencies, causing greater intermodulation distortion. The Tannoy style of coaxial, with the woofer forming part of the high frequency horn, had greater intermodulation distortion.

1938/1939, 2 KhT-26 and 4 KhT-130 were repaired at the Varkaus Tank Workshop and put into service until June 1941. The Finns also rearmed their Vickers 6-Ton tanks with the Soviet 45 mm 20K gun and the coaxial DT tank machine gun for ammunition standardization with captured T-26s. These modified Vickers tanks under designator T-26E were used by the Finnish Army during the Continuation War for infantry support.

Fixed vertical axis perpendicular to the line of measurement, with a horizontal axis parallel to the main output direction of the light source Type C are single column structures. The single column structure is created when the assistant column is taken down from double columns structure. This type is applied to a fixed tube lamp, spot lamp, or other devices. The axis radiation of lamp and the horizontal of rotating supporter is coaxial.

The image's handedness is not changed by the Schmidt-Pechan. The design of the two prisms is such that the entrance beam and exit beam are coaxial, i.e. the Schmidt–Pechan prism does not deviate the beam if centered on the optical axis. The "roof" section of the upper prism flips (reverts) the image laterally with two total internal reflections in the horizontal plane from the roof surface: once on each side of the roof.

Consequently, a one-meter high-impedance direct (1×) coaxial probe may load the circuit with a capacitance of about 110 pF and a resistance of 1 megohm. Oscilloscope probes are characterised by their frequency limit, where the amplitude response has fallen by 3 dB, and/or by their rise time t_r. These are related as (in round figures) :f_{3 dB} = 0.35/t_r Thus a 50 MHz probe has a rise time of 7 ns.

Instead the local cable company rebroadcast this station on the FM dial. Cable subscribers who plugged their coaxial cable into their stereo could listen to KVOC, and channels like HBO through the stereo. This service was known as cable stereo, or cable radio, or cable FM. KVOC went off the air for a time. The station was brought back to life in 2013, and was reported to be planning to air an all talk format.

University Radio Exeter was founded in 1976, under the stairs of Devonshire House on the campus of the University of Exeter. At that time, of course, the only means of broadcasting was very low power, using induction loop aerials to broadcast to Halls of residence. Initially the transmitter was installed in the studio. This meant feeding a coaxial cable, carrying the RF signal, just below ground level from Devonshire House to Lafrowda halls of residence.

Communicating data from one location to another requires some form of pathway or medium. These pathways, called communication channels, use two types of media: cable (twisted-pair wire, cable, and fiber-optic cable) and broadcast (microwave, satellite, radio, and infrared). Cable or wire line media use physical wires of cables to transmit data and information. Twisted- pair wire and coaxial cables are made of copper, and fiber-optic cable is made of glass.

In August 1987 New York based LAN Systems, Inc. completed the equipment testing and praised SynOptics for successfully deploying a 10Mbit/s network that supported workstations up to 330 feet from the wiring closet, because of their careful control of EMI and RFI. Novell reported that the LattisNet equipment performed better than RG-58U coaxial cable. This same year HP proposed a study group be formed to look into standardizing Ethernet on telephone wires.

The FV107 Scimitar is very similar to the Scorpion but carries the 30mm RARDEN cannon as its main weapon. Secondary armament consists of a coaxial GPMG and multi-barrelled smoke grenade dischargers. Stowage is provided for 201 rounds of 30 mm and 3,000 rounds of 7.62 mm ammunition. In 2006, the British Army had 328 in service; these are expected to be replaced by the scout version of the Future Rapid Effect System.

Ethernet has evolved to include higher bandwidth, improved medium access control methods, and different physical media. The coaxial cable was replaced with point-to-point links connected by Ethernet repeaters or switches. Ethernet stations communicate by sending each other data packets: blocks of data individually sent and delivered. As with other IEEE 802 LANs, adapters come programmed with globally unique 48-bit MAC address so that each Ethernet station has a unique address.

Protector Dual RWS is an extension of the existing RWS family that includes the use of two weapons. This innovative system also provides a dual user functionality (Gunner / Commander). The coaxial weapon is mounted on the same axis as the main gun, the system automatically compensates for the parallel axis between the sights and the axis. Switching between weapons is intuitive and happens by simply pushing a button depending on mission need.

This gives the planar technologies a big economic advantage over other types, such as coaxial line. Some authors make a distinction between transmission line, a line that uses a pair of conductors, and waveguide, a line that either does not use conductors at all, or just uses one conductor to constrain the wave in the dielectric. Others use the terms synonymously. This article includes both kinds, so long as they are in a planar form.
|
|
The conductors are separated from the ground planes, sometimes with air between them but more often with a solid dielectric material. Transmission lines can also be constructed in non-planar formats such as wires or coaxial line. As well as interconnections, there are a wide range of circuits that can be implemented in transmission lines. These include filters, power dividers, directional couplers, impedance matching networks, and choke circuits to deliver biasing to active components.

Due to the text color on the original models, these terminals are informally known as green screen terminals. Unlike Teletype terminals, the Uniscope minimizes the number of I/O interrupts required by accepting large blocks of data, and uses a high speed proprietary communications interface, using coaxial cable and hardware devices known as multiplexors. A Uniscope operator awaits a prompt from the remote mainframe. The prompt indicates that the mainframe is ready to receive input.

No such pulse meant that the dielectric must not have held a charge. The smaller capacity 256-bit (128 by 2 bits) "production" device was in a similar vacuum-tube envelope. It was built with two storage arrays of discrete "eyelets" on a rectangular plate, separated by a row of eight cathodes. The pin count was reduced from 44 for the 4096-bit device down to 31 pins and two coaxial signal output connectors.

The escapement was commercialized in 1999 by Omega SA when it introduced the first mass- produced watch incorporating the technology.Xavier Markl, The coaxial escapement, Monochrome-watches, Dec. 26, 2000, quoting Odets, W. It is the only other escapement produced at industrial scale, other than the Swiss lever escapement. When it first came to the market as the Caliber 2500, it had an oscillation rate of 28,800 bph (8 bt/s), considered a "hi-beat" movement.

Most providers require the use of a set top box to view their television services. Digital networks have far more sophisticated trunking systems. The five main Cities (Dublin, Cork, Galway, Limerick, and Waterford), along with towns like Longford, Dungarvan, Clonmel, Thurles, Kilkenny etc. now enjoy state of the art Hybrid fibre-coaxial networks which are used to deliver a myriad of services, including digital TV, broadband DOCSIS 3.0, and cable telephony services.

The design is a refinement of the proven Ka-26, featuring interchangeable mission pods. The aircraft is fitted with a new rotor system, increased visibility nose, and new passenger cabin design. The Ka-226 also features a new transmission system and is made largely from composite materials. The aircraft is fitted with trademark Kamov coaxial rotors, of advanced composite design, making the Ka-226 highly manoeuvrable and eliminating the need for a tail rotor.

Directly below the fan, was a UHF connector that produced composite video output. This could be connected to a monitor, or with a bit of work, a conventional television. The processor was near the back of the machine, with the memory and video circuits at the front. This required the video output to be routed to the back of the machine with a coaxial cable running across the top of the card.

Upon reception at the other end, the balun takes the difference of the two signals, thus removing any noise picked up along the way and recreating the unbalanced signal. A once common application of a radio frequency balun was found at the antenna terminals of a television receiver. Typically a 300-ohm balanced twin lead antenna input could only be connected to a coaxial cable from a cable TV system through a balun.

However it does correspond to one type of measurement of SWR using what was formerly a standard measuring instrument at microwave frequencies, the slotted line. The slotted line is a waveguide (or air-filled coaxial line) in which a small sensing antenna which is part of a crystal detector or detector is placed in the electric field in the line.

Schematic of a wave moving rightward down a lossless two-wire transmission line. Black dots represent electrons, and the arrows show the electric field. One of the most common types of transmission line, coaxial cable. In radio- frequency engineering, a transmission line is a specialized cable or other structure designed to conduct alternating current of radio frequency, that is, currents with a frequency high enough that their wave nature must be taken into account.

The Very Large Array, an interferometric array formed from many smaller telescopes, like many larger radio telescopes. In 1946, a technique called astronomical interferometry was developed. Astronomical radio interferometers usually consist either of arrays of parabolic dishes or two-dimensional arrays of omni-directional antennas. All of the telescopes in the array are widely separated and are usually connected together using coaxial cable, waveguide, optical fiber, or other type of transmission line.

Sigma bonds occur when the orbitals of two shared electrons overlap head-to-head. Pi bonds occur when two orbitals overlap when they are parallel. For example, a bond between two s-orbital electrons is a sigma bond, because two spheres are always coaxial. In terms of bond order, single bonds have one sigma bond, double bonds consist of one sigma bond and one pi bond, and triple bonds contain one sigma bond and two pi bonds.

In the turret rear back there was the commander's cupola, well equipped with optical equipment. The turret had an optical rangefinder. The first two prototypes had twin 7.5 mm Reibel machine guns placed on top of the roof as an AA-weapon, a third was coaxial. In the first design proposal for a 120 mm version, the conventional turret had a high cupola armed with both a machine gun and a 20 mm MG 151 rapid fire cannon.

Wood poles can also be used for low voltage distribution to customers. Poles in Ottawa, Ontario, Canada Today, utility poles may hold much more than the uninsulated copper wire that they originally supported. Thicker cables holding many twisted pair, coaxial cable, or even fibre-optic, may be carried. Simple analogue repeaters or other outside plant equipment have long been mounted against poles, and often new digital equipment for multiplexing/demultiplexing or digital repeaters may now be seen.

NMR is also useful for investigating nonstandard geometries such as bent helices, non-Watson–Crick basepairing, and coaxial stacking. It has been especially useful in probing the structure of natural RNA oligonucleotides, which tend to adopt complex conformations such as stem-loops and pseudoknots. NMR is also useful for probing the binding of nucleic acid molecules to other molecules, such as proteins or drugs, by seeing which resonances are shifted upon binding of the other molecule.

Espenschied worked as an engineer for Telefunken Wireless Telegraph Company during 1909–1910. He later worked for the American Telephone and Telegraph Company, before directing high-frequency transmission development for Bell Telephone Laboratories. In 1916, while at Bell Telephone Laboratories, he co-created with Herman Affel the first modern coaxial cable, which paved the way for television. The cable advanced long distance telephone service, making it possible to carry thousands of simultaneous phone calls on long distance circuits.

The project was started in October 1989 with the prototype first flying in June 1994 originally with a single engine. It was later rebuilt with two Hirth F30A two- stroke engines. The lifting vehicle is an open frame with one person standing on top with a protective tubular framework. Below the framework the vehicle has two coaxial contra-rotating two-blade rotors with directional control from two small propellers at the ends of the cross-tubes.

Coaxial stacking is the tendency of nucleic acid blunt ends to bind to each other, by interactions between the exposed bases. There are three possible conformers: an unstacked form and two stacked forms. The unstacked form dominates in the absence of divalent cations such as Mg2+, because of electrostatic repulsion between the negatively charged backbones of the strands. In the presence of at least about 0.1 mM Mg2+, the electrostatic repulsion is counteracted and the stacked structures predominate.

In April 2012, BAE unveiled a potential version of the system mount, developed in collaboration with Rafael Advanced Defense Systems. It is visually distinctive from previous versions with its stealthy housing, which also protects the gun from weather and allows for easier access to internal components through large access panels. The upgrade mounts a larger Alliant Techsystems Mk44 Bushmaster II 30 mm cannon for a 500-meter range increase, as well as a coaxial M2 .50 caliber machine gun.

In the most basic form, a quarter-wavelength section of coaxial cable is prepared such that the inner and outer conductors are separate but still attached to the remaining cable. The outer (shield) conductor is connected to a quarter- wavelength conducting sleeve into which the cable is inserted, and the inner conductor protrudes vertically above the sleeve for a quarter-wavelength. Also, additional quarter-wavelength sections may be connected to the outer conductor to form a better ground plane.

QH-50 on board the destroyer USS Allen M. Sumner (DD-692) during a deployment to Vietnam between April and June 1967 Having two coaxial sets of rotors provides symmetry of forces around the central axis for lifting the vehicle and laterally when flying in any direction. Because of the mechanical complexity, many helicopter designs use alternate configurations to avoid problems that arise when only one rotor is used. Common alternatives are single-rotor helicopters or tandem rotor arrangements.

The Skyblazer features two coaxial, contra- rotating main rotors, a single-seat open cockpit without a windshield, skid- type landing gear and two twin-cylinder, air-cooled, two-stroke, dual-ignition Rotax 503 engines for redundancy. The two engines were provided due to the aircraft lacking collective pitch control, thus precluding an autorotation in the event of a power loss. The aircraft can reportedly hover on one engine. The aircraft fuselage is made from welded steel tubing.

1909 Brişcu was the first engineer to begin experimenting with the cyclic variation of rotor blade pitch to ensure horizontal flight and stability in helicopters. He invented a prototype "air- carriage" with all the features of a helicopter-like flying-machine: horizontal, vertical and lateral movement and fixed-point landing. It was equipped with two coaxial propellers rotating in opposite directions. This was flown experimentally by the French aviator Paul Cornu, who built a prototype with an Antoinett engine.

Digital television transition is still an ongoing process in Kosovo, limiting the analog television broadcast domain to only three national channels. Due to this conditions all four major telecommunications companies in Kosovo now broadcast digital TV on other mediums. While IPKO and Kujtesa have chosen to reuse the existing coaxial network, PTK which offers xDSL services went for IPTV, Artomotion offers digital TV to selected users in Pristina. IPKO has recently launched an IPTV solution, tailored towards mobile customers.

Because of this, the coaxial escapement should in theory perform effectively without lubrication. This mode of impulse is in theory superior to the lever escapement, which has engaging friction on the entry pallet. For long this was recognized as a disturbing influence on the isochronism of the balance. Purchasers no longer buy mechanical watches primarily for their accuracy, so manufacturers had little interest in investing in the tooling required, although finally Omega adopted it in 1990.

While working at Hazeltine Corporation, Dr. Salati was awarded United States patent #2,540,012 which was the basis for what is now commonly known as the BNC connector. The patent for Electrical Connector was filed May 19, 1945, and issued January 30, 1951. Electrical Connector, United States patent #2,540,012 BNC is an acronym for Bayonet Neill–Concelman. The BNC connector is still in common use for coaxial cables that carry high frequency currents between pieces of electronics and communications equipment.

Mobile telephony has the advantage of reaching all areas at a lower cost, and the total number of mobile lines is almost two times that of landlines, with an estimation of 63 million lines. The telecommunication industry is regulated by the government through Cofetel (Comisión Federal de Telecomunicaciones). The Mexican satellite system is domestic and operates 120 earth stations. There is also extensive microwave radio relay network and considerable use of fiber-optic and coaxial cable.

The Schwimmpanzer II could make 5.7 km/h in the water. An inflatable rubber hose around the turret ring created a waterproof seal between the hull and turret. The tank's 2 cm gun and coaxial machinegun were kept operational and could be fired while the tank was still churning its way ashore. Schwimmpanzer IIs were deployed from a specially modified landing barge (Type C) and could be launched directly into open water from a hatch cut into the stern.

The turrets were mounted side-by-side, each covering 120° to each side of the longitudinal axis of the tank. These were crewed by four people: two machine gunners, a commander, and a driver. While the Type B had a single turret, armed with a short low-velocity QFSA 47mm cannon and a coaxial 7.65 water- cooled machine gun. This turret contained two crew members, a commander and a gunner, who also served as a loader.

Some military facilities and/or aircraft will also utilize Mode S. Returns from both radars at the ground station are transmitted to the ATC facility using a microwave link, a coaxial link, or (with newer radars) a digitizer and a modem. Once received at the ATC facility, a computer system known as a radar data processor associates the reply information with the proper primary target and displays it next to the target on the radar scope.

He then connected several of his customers who were located along the cable path. This was the first community antenna television (CATV) system in the United States. Walson's company grew over the years, and he is recognized as the founder of the cable television industry. He was also the first cable operator to use microwave to import distant television stations, the first to use coaxial cable to improve picture quality, and the first to distribute pay television programming.

Apart from the first stage nozzle guide vanes, the LP turbine was completely statorless, with four consecutive rotor stages. Rotors one and three drove the front fan clockwise (viewed from the front), whereas the rear fan was driven anticlockwise by rotors two and four. Although the front fan had inlet guide vanes, there were no vanes between the contra-rotating fan rotors or, downstream, any exit guide vanes. The core and bypass streams exhausted through separate coaxial propelling nozzles.

Cable-ready television sets have coaxial cable F connectors. One end connects to the cable, antenna, or VHF jack on the back of the television set; the other end connects to the wall CATV outlet. Once the television is connected through the cable to the wall CATV outlet, the television will need to be programmed to receive the cable channels. The instruction manual that came with the television should have instructions on how to program cable channels.

Beginning in March, 1959, The station initially "broadcast" to the CUA campus via AM carrier current. Although eventually replaced by FM carriers, some dormitories were still served by AM as late as the 1980s. During the 1970s, the university had hopes of a campus-wide closed- circuit television service to dormitories and other buildings. Although the TV service was not developed, the coaxial cable buried between buildings allowed the radio station to broadcast on an FM wavelength.

The basic advantage of using an unbalanced circuit topology, as compared to an equivalent balanced circuit, is that far fewer components are required. The difficulties come when a port of the circuit is to be connected to a transmission line or to an external device that requires differential input or output. Many transmission lines are intrinsically an unbalanced format such as the widely used coaxial cable. In such cases the circuit can be directly connected to the line.

Both of these devices will split a single outlet to multiple devices. Cable splitters also operate in many homes, allowing a single coaxial cable to provide cable television to multiple sets. Some systems may even use an A/B box, a device that connects multiple sets of devices to the same system, with users switching between them by flipping between the A or B mode. These devices all perform the same basic job that a port expander does.

At VHF frequencies, a sleeve balun can also be built to remove feeder radiation.Sleeve Baluns Another narrow-band design is to use a λ/4 length of metal pipe. The coaxial cable is placed inside the pipe; at one end the braid is wired to the pipe while at the other end no connection is made to the pipe. The balanced end of this balun is at the end where no connection is made to the pipe.

SynOptics Communications was founded in 1985 by Andrew K. Ludwick and Ronald V. Schmidt, both of whom worked at Xerox's Palo Alto Research Center (PARC). The most significant product that Synoptics produced was LattisNet (originally named AstraNet) in 1987. This meant that unshielded twisted-pair cabling already installed in office buildings could be re-utilized for computer networking instead of special coaxial cables. The star network topology made the network much easier to manage and maintain.

Davis recoilless gun mounted in the nose of a F5L flying boat, with a coaxial Lewis machine gun. Photo from circa 1918. The earliest known example of a design for a gun based on recoilless principles was created by Leonardo Da Vinci in the 15th or early 16th century. This design was of a gun which fired projectiles in opposite directions, but there is no evidence any physical firearm based on the design was constructed at the time.

Soon after television broadcasting switched from analog to digital broadcasting, indoor antenna marketing evolved beyond the traditional "rabbit ears." Flat antennas are lightweight, thin, and usually square-shaped with the claim of having more omnidirectional reception. They connect to televisions only with a coaxial cable; they may also be sold with a signal amplifier requiring a power source. Internally, the thin, flat square is a loop antenna, with its circular metallic wiring embedded into conductive plastic.

The two cavity resonators are in center, linked by a short coaxial cable to provide positive feedback. The electrons then pass through a second cavity, called the "catcher", through a similar pair of grids on each side of the cavity. The function of the catcher grids is to absorb energy from the electron beam. The bunches of electrons passing through excite standing waves in the cavity, which has the same resonant frequency as the buncher cavity.

The vehicle is armed with a 73 mm 2A28 Grom gun and a 7.62 mm PKT coaxial tank machine gun. Mounted on the mantlet is the 9S428 ATGM launcher capable of firing 9M14 Malyutka (NATO: AT-3A Sagger A) and 9M14M Malyutka-M (NATO: AT-3B Sagger B) ATGMs (for which the vehicle carries two ATGMs in the turret). There are also two 7.62 mm PKT machine guns in fixed mounts, one in each corner of the bow.

The LINK 480Z supported a proprietary 800 kbit/s CHAIN local area network that ran over a coaxial cable in a similar manner to 10BASE2 Ethernet. Each station on the network required a unique, 8-bit network address that was set by means of a DIP switch on the rear of the unit. Using the built-in Z-Net firmware a diskless 480Z could be directly booted from a network file server (typically a Research Machines 380Z).

Many channels can be transmitted through one coaxial cable by a technique called frequency division multiplexing. At the headend, each television channel is translated to a different frequency. By giving each channel a different frequency "slot" on the cable, the separate television signals do not interfere with each other. At an outdoor cable box on the subscriber's residence the company's service drop cable is connected to cables distributing the signal to different rooms in the building.

A switch or adjustment that covers at least the range between and is common in professional equipment. ;dBm0s :Defined by Recommendation ITU-R V.574.; dBmV: dB(mVRMS) – voltage relative to 1 millivolt across 75 Ω. Widely used in cable television networks, where the nominal strength of a single TV signal at the receiver terminals is about 0 dBmV. Cable TV uses 75 Ω coaxial cable, so 0 dBmV corresponds to −78.75 dBW (−48.75 dBm) or approximately 13 nW.

"The helicopter top in China led to nothing but amusement and pleasure, but fourteen hundred years later it was to be one of the key elements in the birth of modern aeronautics in the West." Chinese Inventions Early Western scientists developed flying machines based upon the original Chinese model. The Russian polymath Mikhail Lomonosov developed a spring-driven coaxial rotor in 1743, and the French naturalist Christian de Launoy created a bow drill device with contra-rotating feather propellers.

A coaxial igniter consists of a fully insulated conductor, covered by four strips of aluminum foil. All of this is further insulated in a tube about 1.6 cm in diameter that is perforated with small holes. The idea is to use an electrical flow through the conductor and then exploding the flow into vapor and then breaking it down into plasma. Consequently, the plasma escapes through the constant perforations throughout the insulating tube and initiates the surrounding propellant.

Nagra double modulometer The 'modulometer' is a proprietary type of quasi-PPM found on Nagra products. It has an integration time (−2 dB) of 7.5 ms, and a semi- logarithmic scale with an appearance between that of a VU meter and a DIN-type PPM. A stereo version ("double modulometer") uses a meter movement with two coaxial needles. In typical practice for Nagra analogue tape recorders, Alignment Level is regarded as −8 and maximum level 0.

The station had easy access to network coaxial cable, which already ran a block away from its studios. WHUM-TV boasted one of the most impressive facilities in early UHF broadcasting and was described by Television Digest as "the first high-powered UHF station". The tower rose from atop a site on Blue Mountain near Summit Station, delivering a signal with an effective radiated power of 260,000 watts—then the highest in use at any UHF facility.

An Ethernet extender (also network extender or LAN extender) is any device used to extend an Ethernet or network segment beyond its inherent distance limitation which is approximately for most common forms of twisted pair Ethernet. These devices employ a variety of transmission technologies and physical media (wireless, copper wire, fiber-optic cable, coaxial cable). The extender forwards traffic between LANs transparent to higher network-layer protocols over distances that far exceed the limitations of standard Ethernet.

The dye cell is placed in the middle, providing a more even distribution of pumping light, and more efficient transfer of energy. The hollow flashlamp also has lower inductance than a normal flashlamp, which provides a shorter flash discharge. Rarely, a "coaxial" design is used for dye lasers, which consists of a normal flashlamp surrounded by an annular shaped dye cell. This provides better transfer efficiency, eliminating the need for a reflector, but diffraction losses cause a lower gain.

IBM saw the value of PCs as being a catalyst to sell more mainframe computers and understood that a LAN of the type Sytek made was superior to dedicated runs of RG-62 coaxial cable, which were required for 327X terminals and controllers. These IBM PC Network cards were available, from IBM for about $700 ea. In the mid-80s, IBM moved its focus to Token Ring, and much of the rest of the market moved to Ethernet.

Also, major manufacturers have announced that they will increasingly produce smart TVs in the mid-2010s. Smart TVs with integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s. Television signals were initially distributed only as terrestrial television using high-powered radio-frequency transmitters to broadcast the signal to individual television receivers. Alternatively television signals are distributed by coaxial cable or optical fiber, satellite systems and, since the 2000s via the Internet.

Physically, a helical resonator is a wire helix surrounded by a square or cylindrical conductive shield. One end of the helix is connected to the shield and the other end is left open (Weston, 2001, p. 660). The device works like a coaxial resonator, but it is much shorter because the helical inner conductor reduces the velocity of wave propagation (Lancaster, 2006, p. 99). Like cavity resonators, helical resonators can achieve Q factors in the 1000s.

The driving impedance of the antenna is equal to the characteristic impedance of the wire with respect to ground, somewhere between 400 and 800 ohms, depending on the height of the wire. Typically a length of 50-ohm or 75-ohm coaxial cable would be used for connecting the receiver to the antenna endpoint. A matching transformer should be inserted between any such low-impedance transmission line and the higher 470-ohm impedance of the antenna.

Van Vanthoff was born in Cobram, Victoria on 12 January 1894 to parents Isaac and Mary Jane Vanthoff. In World War I, Vanthoff served in the Australian Naval and Military Expeditionary Force. He was appointed Director-General of Posts and Telegraphs, heading the Postmaster-General's Department, in May 1958. In the role, he oversaw development of an automatic teleprinter switching system for telegraphs, and worked to provide a six-tube coaxial cable between Sydney and Melbourne.

While the power turbine may be integral with the gas generator section, many turboprops today feature a free power turbine on a separate coaxial shaft. This enables the propeller to rotate freely, independent of compressor speed. Residual thrust on a turboshaft is avoided by further expansion in the turbine system and/or truncating and turning the exhaust 180 degrees, to produce two opposing jets. Apart from the above, there is very little difference between a turboprop and a turboshaft.

From a technical point of view, the bridge consists of two parts. The first part includes two arches crossing the river Mže and the second part consists of three smaller arches that serve as the "flood bridge". The bridges are not coaxial and there is a bridge gate between them that is supported by a 5.15 meter wide pillar. The tower facade is decorated with letter sgraffito, and the original hexagonal pyramid roof is covered with pantiles.

Mn2(CO)10 has no bridging CO ligands: it can be described (CO)5Mn-Mn(CO)5. There are two kinds of CO ligands; one CO on each Mn is coaxial with the Mn-Mn bond (293 pm), and four on each manganese that are perpendicular to it (equatorial). In the stable rotamer, the two Mn(CO)5 subunits are staggered. The overall molecule thus belongs to the point group D4d, which is an uncommon symmetry shared with S2F10.

The design was based on and fit to replace the Ka-27 with a pointed streamlined nose. Reportedly powered by two 1,838 kW (2,465 shp) Klimov TVA-3000 turboshaft engines, driving a coaxial rotor system. The civil variant could carry a 7,000 kg (15,432 lb) underslung load, while the military naval variant can include an array of ASW weapons and electronics. Armament is expected to include APR-3 water-jet-propelled torpedoes and KAB-250PL guided depth charges.

The ground planes or shielding enclosures can behave as hollow waveguides and propagate these modes. Suppression can take the form of shorting screws between the ground planes or designing the enclosure to be too small to support frequencies as low as the operational frequencies of the circuit. Similarly, coaxial cable can support circular TE and TM modes that do not require the centre conductor to propagate, and these modes can be suppressed by reducing the diameter of the cable.

Transitions between the various types are therefore required. Transitions between types using unbalanced conductive lines are straightforward: this is mostly a matter of providing continuity of the conductor through the transition and ensuring a good impedance match. The same can be said for transitions to non-planar types such as coaxial. A transition between stripline and microstrip needs to ensure that both ground planes of the stripline are adequately electrically bonded to the microstrip ground plane.

This led to a minor redesign that produced the XR-7755-3, using a new propeller gearing system driving a set of coaxial shafts to power a set of contra-rotating propellers. The propeller reduction gearing also had two speed settings to allow for a greater range of operating power than adjustable props alone could deliver. Another minor modification resulted in the XR-7755-5, the only change being the replacement of carburetors with a new fuel injection system.

Of great importance to accuracy is the fit of the ammunition to the barrel. The chamber should be concentric, and the throat sized just slightly larger than the bullet diameter. The cartridge must headspace correctly, be held firmly in place, concentric to the bore, and the bullet must fit the bore and be guided to engage the rifling cleanly. Once the bullet is engaged in the rifling, with a good seal and coaxial fit, it must stay that way.

The losses in a fibre system are almost negligible so very long cable runs of hundreds of metres are possible without any signal reinforcement. Because the signal is carried as a beam of light, it is impervious to the electrical interference that even the best coaxial satellite cable may suffer, and cables can be safely and conveniently run alongside mains power cables. Power consumption is also lower than an equivalent electrical system. SAT Fibre Optics Triax.

21–7, 21–50 At microwave frequencies, passive circuits such as filters, power dividers and directional couplers tend to be constructed as distributed-element circuits. These circuits can be constructed using any transmission line format. The coaxial line format commonly used for interconnecting devices has been used for this kind of device construction but is not the most convenient format for manufacturing. Stripline was developed as a better solution for circuit construction and air stripline too fills this role.

The phase shift network inside a subarray is analogue, consisting of different lengths of coaxial cable delay line switched into the signal path, whereas the phasing between subarrays is planned to be digital. The beamwidth (HPBW) of a single subarray beam at 40 MHz is about 20.4°. The estimate is consistent with the direct measurements that give 22±2°.Konovalenko, O.O., Tokarsky, P.L., Yerin, S.N.: Effective Area of Phased Antenna Array of GURT Radio Telescope. Proc.

In telecommunication, a filled cable is a cable that has a non-hygroscopic material, usually a gel called icky-pick, inside the jacket or sheath. The nonhygroscopic material fills the spaces between the interior parts of the cable, preventing moisture from entering minor leaks in the sheath and migrating inside the cable. A metallic cable, such as a coaxial cable or a metal waveguide, filled with a dielectric material, is not considered as a filled cable.

On 15 September 2009 YouSee decided to unencrypt its digital TV distribution, under the marketing name YouSee Clear. However, a parallel analogue distribution was maintained for customers with TV sets that were unable to receive digital signals. At the time YouSee distributed channels in both MPEG-2 and MPEG-4 but in April 2013, YouSee stopped this simulcasting to focus on MPEG-4 only. The name YouSee Clear was used until 1 July 2014 when it was renamed YouSee Tv. The analogue TV signal was finally switched off on February 9, 2016. In early 2017, YouSee switched off their cable radio services, which had been used to redistribute several Danish and foreign FM radio stations. YouSee had however continued to provide radio service via the DVB-C signal and via their set-top box - this was discontinued on 30 December 2020. Today, YouSee broadcasts digital television over coaxial cable and optical fiber using DVB-C and MPEG-4. YouSee also offers IPTV over coaxial cable, optical fiber and copper telephone cables.

On ships, vehicles and aircraft machine guns are usually mounted on a pintle mount – basically a steel post that is connected to the frame or body. Tripod and pintle mounts are usually used with spade grips. The last major mounting type is one that is disconnected from humans, as part of an armament system, such as a tank coaxial or part of an aircraft's armament. These are usually electrically fired and have complex sighting systems, for example, the US Helicopter Armament Subsystems.

RG-6 cable is typically used for satellite feed lines. In this application, there would be a diplexer on the roof that joins the satellite dish feed and the TV antenna together into a single coaxial cable. That cable would then run from the roof into the house. At a convenient point, a second diplexer would split the two signals apart; one signal would go to the TV set and the other to the IRD of the DBS set-top box.

Front suspension was of the double wishbone type. The upper wishbone consisted of a stamped steel control arm, the lower one of a stamped steel link and an adjustable forward radius rod. Coaxial coil springs and hydraulic dampers were attached to the upper wishbone; an anti-roll bar was fitted. On 2.0-litre cars, the rear suspension consisted of a rigid axle on semi-elliptic springs (single-leaf on the spider, two-leaf on the coupé) and twin hydraulic dampers on each side.

The situation progressed for about seven minutes, with the troop commander calling cease fire after two volleys, thinking the "enemy forces" were contained and waiting for them to surrender. The squadron commander then arrived on the scene in his Bradley Fighting Vehicle and opened fire when he thought one of the engineers, still believed to be Iraqis, was trying to escape. When the shooting was over, one engineer was wounded and another, Corporal Lance Fielder of Tennessee, was dead from coaxial machinegun fire.

An N1500 video recorder, with wooden cabinet In 1970, Philips developed a home video cassette format specially made for a TV station in 1970 and available on the consumer market in 1972. Philips named this format "Video Cassette Recording" (although it is also referred to as "N1500", after the first recorder's model number). The format was also supported by Grundig and Loewe. It used square cassettes and half-inch (1.3 cm) tape, mounted on coaxial reels, giving a recording time of one hour.

Pertec's primary line of computer products was aimed at the key-to-disk minicomputer systems that were used as front-end data processors for the IBM 360/370 and similar systems. This line was opened in the first half of the 1970s by the Pertec PCC-2100 data entry system, which was essentially different from the PCC-2000 mentioned above. The system was able to serve up to 16 coaxial terminals, two D3000 disk drives and one T1640 tape drive.

The July 1944 unofficial record of the Me 163B V18 was officially surpassed in November 1947, when Chuck Yeager flew the Bell X-1 to . The official speed record for a seaplane moved by piston engine is , which attained on 23 October 1934, by Francesco Agello in the Macchi-Castoldi M.C.72 seaplane ("idrocorsa") and it remains the current record. It was equipped with the Fiat AS.6 engine (version 1934) developing a power of at 3300 rpm, with coaxial counter-rotating propellers.

Chipcom was an early pioneering company in the Ethernet hub industry. Their products allowed Local Networks to be aggregated in a single place instead of being distributed across the length of a single coaxial cable. They competed with now-gone companies such as Cabletron Systems, SynOptics, Ungermann-Bass, David Systems, Digital Equipment Corporation, and American Photonics, all of which were early entrants in the "LAN Hub" industry. Chipcom also was involved in Token Ring, FDDI, and Asynchronous Transfer Mode (ATM).

Twisted pair cabling is the most popular network cable and is often used in data networks for short and medium length connections (up to 100 meters or 328 feet). This is due to its relatively lower costs compared to optical fiber and coaxial cable. Unshielded twisted pair (UTP) cables are the primary cable type for telephone usage. In the late 20th century, UTPs emerged as the most common cable in computer networking cables, especially as patch cables or temporary network connections.

This pattern has advantages to daisy chain loops. Installation tools, tips, and techniques for networked wiring systems using twisted pairs, coaxial cables, and connectors for each are available. Structured wiring competes with wireless systems in homes. While wireless systems certainly have convenience advantages, they also have drawbacks over copper-wired systems: the higher bandwidth of systems using Category 5e wiring typically support more than ten times the speeds of wireless systems for faster data applications and more channels for video applications.

Other survivability features include twin-engine design for redundancy, protection for vital aircraft systems, and crash absorbing land gear and fuselage. Also, the coaxial main rotor configuration does not require tail rotor, which can improve survivability. It is the world's first operational helicopter with a rescue ejection system, which allows the pilot to escape at all altitudes and speeds. The K-37-800 rocket-assisted ejection system is manufactured by the Zvezda Research and Production Enterprise Joint Stock Company in the Moscow region.

In 1933 he and Sally P. Mead began analysis of waveguide propagation discovered analytically by their colleague George C. Southworth. Their analysis uncovered the transverse modes. Schelkunoff appears to have been the first to notice the important practical consequences of the fact that attenuation in the TE01 mode decays inversely with the 3/2 power of the frequency. In 1935 he and his colleagues reported that coaxial cable, then new, could transmit television pictures or up to 200 telephone conversations.

Fiber management systems surfaced with fiber optic cable technology in the early 1970s. Peter Schultz, Donald Keck, and Robert Maurer developed the first optical fiber that could transmit digital data more than 65,000 times faster than coaxial cables. In April 1977, General Telephone and Electronics launched the first optical network, in Southern California. The next month, Bell launched an optical telephone system in Chicago. Since the 1970s, fiber networks have grown to service over 80% of the world’s data and voice traffic.

Supported by Nokia Siemens, the network is capable of delivering Triple Play services that consist of data (Internet or intranet), voice (VoIP), and video (interactive TV and multimedia) in a single infrastructure. This network is capable of supporting up to 1 Gbyte/s data transfer. First Media, a company born from Lippo group's new $650 million investment in Internet in Indonesia, as well as cable television, began offering FTTH (using coaxial cable, not Optical fiber), branded as FastNet, on 8 September.

The electric field reversal at Lm clearly indicates a reversal of the plasma drift within the inner and the polar magnetosphere. In a more sophisticated model, the auroral oval between about 15° and 20°colatitude (again simulated by a coaxial auroral zone), as a transition zone between the field reversal, has been taken into account. The ionospheric dynamo region between about 100 to 200 km altitude is a region where ions and electrons have different mobility. Thus the plasma becomes electrically conducting.

Interrogating pulses are directed from the antenna to the receiver, and reply pulses are directed from the transmitter to the antenna. The preselector, consisting of three coaxial cavities, attenuates all RF signals outside the receiving band. The received signal is heterodyned to a 50 MHz intermediate frequency in the mixer and amplified in the IF amplifier which also contains the detector. In case of coded transmission, the decoder module provides a pulse output only if the correct spacing exists between pulse pairs received.

Coaxial downdraft gasification stove Certain stove designs are, in effect, gasifiers working on the updraft principle: The air passes up through the fuel, which can be a column of rice hulls, and is combusted, then reduced to carbon monoxide by the residual char on the surface. The resulting gas is then burnt by heated secondary air coming up a concentric tube. Such a device behaves very much like a gas stove. This arrangement is also known as a Chinese burner.

The Army version has the same design as the Air Force version, but the design of the delay lines in the Beam Forming Networks inside the Central Building are different. The Army used what is called a "Lumped Constant" delay line design and the Air Force used a "Coaxial" delay line design. The Ramasun Station array was dismantled in 1975 following base closure. During the 1970s, the Japanese government installed two large Wullenweber arrays, similar to the FRD-10, at Chitose and Miho.

RM Nimbus PCs were usually connected to local area network supplied by RM. The company's initial network solution was RM Net, comprising RM Nimbus PC-186 workstations and servers. Later an RM Nimbus AX or VX became the usual choice of fileserver. PC-186 workstations could be designated as print servers, allowing shared access to printers from all workstations. The network used Microsoft MS-Net server and client software, Zilog Z-Net network interface cards, coaxial cable and BNC connectors.

This gave the tank better stability over its predecessor. In contrast to the one-man turret of Type 95, the Type 98 had a two-man turret, which offered more room for the gunner/commander. In the turret was mounted a Type 100 37 mm tank gun with an angle of fire of -15 to +20 degrees, a muzzle velocity of 760 m/s, and also a coaxial 7.7 mm machine gun. The driver was located in a central position of the chassis.

The interface specifications for the BNC and many other connectors are referenced in MIL-STD-348. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut. BNC connectors are used with miniature-to-subminiature coaxial cable in radio, television, and other radio- frequency electronic equipment, test instruments, and video signals. The BNC was commonly used for early computer networks, including ARCnet, the IBM PC Network, and the 10BASE2 variant of Ethernet.

The lanes consist of steel pipes of 65 mm bore and wall thickness of 2.5–3 mm. The pipes are connected with tight couplers 14 cm long to ensure perfect coaxial alignment and then welded together, ensuring air-tightness. To prevent stray voltage from causing excess corrosion, ceramic insulators are inserted between the pipe segments at some places. Pipes buried underground are protected from the outside by a layer of fiberglass, wound around at increased temperature and coated with hot asphalt.

One of the problems with any single set of rotor blades is the torque (rotational force) exerted on the helicopter fuselage in the direction opposite to the rotor blades. This torque causes the fuselage to rotate in the direction opposite to the rotor blades. In single rotor helicopters, the antitorque rotor or tail rotor counteracts the main rotor torque and controls the fuselage rotation. Coaxial rotors solve the problem of main rotor torque by turning each set of rotors in opposite directions.

A Ka-32 coaxial rotor animation Dissymmetry of lift is an aerodynamic phenomenon caused by the rotation of a helicopter's rotors in forward flight. Rotor blades provide lift proportional to the amount of air flowing over them. When viewed from above, the rotor blades move in the direction of flight for half of the rotation (advancing half), and then move in the opposite direction for the remainder of the rotation (retreating half). A rotor blade produces more lift in the advancing half.

DC Blocks are coaxial components that prevent the flow of audio and direct current (DC) frequencies while offering minimum interference to RF signals. There are three basic forms of DC blocks. “Inner only” models have a capacitor in series with the center conductor, “outer only” models have a capacitor in series with the outer conductor, and “inner/outer” models have capacitors in series with both the inner and outer conductors. The insulation material on the outer models is non-conductive.

In addition to serving the traditional communications markets, the Lucent Optoelectronics portion of the facility provided a family of transmitters and receivers for use in network computing applications. Lucent was also a leading player in the cable TV and hybrid fiber coaxial markets. In addition to Reading, Pennsylvania, other Lucent Optoelectronics facilities were located in Breinigsville, Pennsylvania; Murray Hill, New Jersey; Alhambra, California; and Matamoros, Mexico. The Lucent Microelectronics portion of the facility produced linear bipolar, high voltage and gallium arsenide integrated circuits.

The landing gear was tricycle and a full, four surface cruciform tail was fitted, whose ventral fin/rudder unit prevented the coaxial propellers from striking the ground. The pilot and co-pilot sat under twin bubble canopies, and the bombardier sat in the extreme front behind a plexiglass nose.Winchester 2005, p. 27. Defensive armament consisted of two 0.50 in (12.7 mm) machine guns each side in the trailing edge of the wing, which retracted into the wing when not in use.

The turret's firepower was augmented by a coaxial M2 Browning machine gun. The tank commander also made use of a anti-aircraft machine gun on the turret roof.de Mazarrasa (1990), p. 22 The vehicle carried 50 projectiles, 748 rounds and 2,050 bullets.de Mazarrasa (1990), p. 24 The tank commander was issued a cupola which offered ten all-around direct-vision episcopes, and a binocular telescope with 10x magnification. The commander was also given an optical full-field coincidence range finder.

The distribution line is then "tapped" into and used to connect the individual drops to customer homes. These taps pass the RF signal and block the AC power unless there are telephony devices that need the back-up power reliability provided by the coax power system. The tap terminates into a small coaxial drop using a standard screw type connector known as an F connector. The drop is then connected to the house where a ground block protects the system from stray voltages.

They mounted a steel pole on the front bumper that extended above the driver's head because the Germans would sometimes stretch piano wire over roads with the intention of injuring or decapitating the driver. The third vehicle used was the six- wheeled, light-weight M8 Greyhound armored car, mounted with a 37 mm gun in a movable turret that could swing a full 360 degrees. It also featured a .30 caliber coaxial machine gun that could move independently of the turret.

Non-cable-ready television sets are older televisions (e.g., with a rotary knob) with no coaxial cable F connector; a cable converter box or a cable-ready VCR is necessary to receive cable. After ending the analogue CATV transmissions, an (analogue) cable-ready TV or VCR is no longer be able to tune cable channels directly. A customer needs to install a digital cable box or a digital television adapter (which is a very basic kind of digital cable box).

US Army tank troops with Renault FTs on the Western Front, 1918. The FT was the first operational tank to carry a turret. In modern tanks, the turret is armoured for crew protection and rotates a full 360 degrees carrying a single large-calibre tank gun, typically in the range of 105 mm to 125 mm calibre. Machine guns may be mounted inside the turret, which on modern tanks is often on a "coaxial" mount, parallel with the larger main gun.

The male connector has a center pin, and a captive nut with internal threads. The design allows for low-cost construction, where cables are terminated almost exclusively with male connectors. The coaxial cable center conductor forms the pin, and cable dielectric extends up to the mating face of the connector. Thus, the male connector consists of only a body, which is generally crimped onto or screwed over the cable shielding braid, and a captive nut, neither of which require tight tolerances.

The People's Republic of China possesses a diversified communications system that links all parts of the country by Internet, telephone, telegraph, radio, and television. The country is served by an extensive system of automatic telephone exchanges connected by modern networks of fiber-optic cable, coaxial cable, microwave radio relay, and a domestic satellite system; cellular telephone service is widely available, expanding rapidly, and includes roaming service to foreign countries. Fiber to the x infrastructure has been expanded rapidly in recent years.

Alternatively, radial wires placed at the base of the antenna can form a ground plane. For VHF and UHF bands, the radiating and ground plane elements can be constructed from rigid rods or tubes. Using such an artificial ground plane allows for the entire antenna and "ground" to be mounted at an arbitrary height. One common modification has the radials forming the ground plane sloped down, which has the effect of raising the feedpoint impedance to around 50 Ω, matching common coaxial cable.

The purpose of submarine power cables is the transport of electric current at high voltage. The electric core is a concentric assembly of inner conductor, electric insulation and protective layers (resembling the design of a coaxial cable)."Submarine Power Cables - Design, Installation, Repair, Environmental aspects", by T Worzyk, Springer, Berlin Heidelberg 2009 Modern three-core cables (e.g. for the connection of offshore wind turbines) often carry optical fibers for data transmission or temperature measurement, in addition to the electrical conductors.

The voltage drop across the shunt is proportional to its current flow. Both alternating currents (AC) and direct currents (DC) can be measured with the shunt resistor. The high performance coaxial shunt have been widely used for many applications fast rise-time transient currents and high amplitudes but, highly integrated electronic devices prefer low-cost surface mounted devices (SMDs), because of their small sizes and relatively low prices. The parasitic inductance present in the shunt affects high precision current measurement.

Because tank crews have limited visibility from inside the tank, infantry can get close to a tank given enough concealment and if the hatches are closed. If tank crewmen unbutton for better visibility they become vulnerable to small arms fire, grenades and molotov cocktails. An infantryman cannot be targeted by a tank's main gun when close, as it cannot depress sufficiently. Close defense weapons such as pistol ports, hull-, coaxial- and pintle-mounted machine guns gave them some protection however.

Accuracy of the measurement is limited by the accuracy and stability of the reference source. Mechanical methods require a tunable resonator such as an absorption wavemeter, which has a known relation between a physical dimension and frequency. In a laboratory setting, Lecher lines can be used to directly measure the wavelength on a transmission line made of parallel wires, the frequency can then be calculated. A similar technique is to use a slotted waveguide or slotted coaxial line to directly measure the wavelength.

Using RCA connectors, each signal requires its own plug. Even the simple case of attaching a cassette deck may need four of themtwo for stereo input and two for stereo output. In any common setup this quickly leads to a disarray of cables and confusion in how to connect them. This situation is made worse if one considers more complex signals like component video (a total of three for video and two for analog audio or one for digital coaxial audio).

Some large companies emerged: Kappa and RCS in Bucharest, Astral in Cluj, UPC in Timişoara, TourImex in Râmnicu Vâlcea. This consolidation came with gentlemen's agreements over areas of control and pricing, with claims of monopoly abounding. This process of consolidation was completed around 2005–06, when only two big suppliers of cable remained: UPC and RCS&RDS; (DIGI). Internet over coaxial cable has been available since around 2000, and IP telephony (over the CATV infrastructure) since the deregulation of the market in 2003.

Alphonse Pénaud would later develop the coaxial rotor model helicopter toys in 1870, powered by rubber bands. One of these toys, given as a gift by their father, would inspire the Wright brothers to pursue the dream of flight. Before development of powered helicopters in the mid 20th century, autogyro pioneer Juan de la Cierva researched and developed many of the fundamentals of the rotor. De la Cierva is credited with successful development of multi-bladed, fully articulated rotor systems.

For a typical coaxial cable, loading is of the order of 100pF per meter (the length of a typical test lead). Attenuator probes minimize capacitive loading with an attenuator, but reduce the magnitude of the signal delivered to the instrument. A 10× attenuator will reduce the capacitive load by a factor of about 10. The attenuator must have an accurate ratio over the whole range of frequencies of interest; the input impedance of the instrument becomes part of the attenuator.

The cable is now 200 m of thin multi-core containing one coaxial and 5 single wires. As it is not load-bearing, a rope still has to be used and 9 mm static climbing rope was found to be better than anything thinner, including wire rope, at preventing twist. The rope often becomes tangled with the cable, so I.A.Recordings is still looking for a weight-bearing cable. The 180 degree tilt range allows the underside of shaft caps to be inspected.

Those had a different shape of armour including an upright rear armour. Again one prototype had no fixed armament and the second was armed with two coaxial 14.5 mm KPVT heavy machine guns. These were accepted into service as BTR-40 and BTR-40A respectively. The vehicle's drawbacks, such as its poor cross-country performance and problems with crossing water obstacles, compelled the design team to produce, in late 1954, what was planned to be an amphibious variant of the BTR-40.

The structure of the glmS ribozyme was first determined by X-ray crystallography in 2006. The tertiary structure of this RNA is characterized by three coaxial stacked helices, packed side-by-side. The ribozyme core contains a double pseudoknotted structure, which places the central helix P2.1 such that the scissile phosphate is nestled by the major groove. The major groove of the adjacent helix P2.2 is involved in metabolite binding and the scissile phosphate is attached to the 5' end of the helix.

The Type 2 Ke-To was based on the Type 98 Ke-Ni, using the same engine and bell crank suspension. However, the gun turret was enlarged to provide greater space for the crewmen and the main armament was changed to the more powerful Type 1 37 mm gun, with a muzzle velocity of 800 m/s. The new 37 mm gun used gave the tank "slightly better performance". The conical turret also carried a 7.7 mm machine-gun in a coaxial mount.

Ethernet over twisted pair technologies use twisted-pair cables for the physical layer of an Ethernet computer network. They are a subset of all Ethernet physical layers. Early Ethernet used various grades of coaxial cable, but in 1984, StarLAN showed the potential of simple unshielded twisted pair. This led to the development of 10BASE-T and its successors 100BASE-TX, 1000BASE-T and 10GBASE-T, supporting speeds of 10 and 100 megabit per second, then 1 and 10 gigabit per second respectively.

30-caliber machine guns could be mounted on pintles on either side of the turret for anti-aircraft use, bringing the total to nine. Surmounting the superstructure was a small revolving turret armed with a 37 mm gun M3 and a coaxial machine gun. The 37 mm gun could penetrate 46 mm of face-hardened armor sloped 30° at a range of , and 40 mm at .Hunnicutt, R. P. (1992), Stuart: A History of the American Light Tank, Presidio Press, p. 496. .

TCN9 and GTV9 were connected via the coaxial cable in 1963, allowing the instant sharing of news stories and programs between both cities. The cable supported the simultaneous live broadcast of the 5th test of the 1962–63 Ashes series from the Sydney Cricket Ground to Sydney, Canberra and Melbourne – a major milestone in Australian television history. The cable was also used in 1965 for innovative interstate live split-screen link-ups between Graham Kennedy's In Melbourne Tonight and Don Lane's Sydney Tonight.

Though a much larger aircraft, the G.11E used the same coaxial, three blade twin rotor layout as on the Gyroplane Laboratoire. It was initially powered by a fan cooled Potez 9E nine cylinder radial engine mounted amidships, under the concentric rotor shafts. There was 6.5:1 speed reduction gearing between the engine and the rotor drive. The rotors are built around tapered tube spars, which carry ribs and are Dural clad at the leading edges and with alloy over 3-ply elsewhere.

Gonâve Microplate showing main fault zones. The Enriquillo–Plantain Garden fault zone (EPGFZ or EPGZ) is a system of active coaxial left lateral-moving strike slip faults which runs along the southern side of the island of Hispaniola, where Haiti and the Dominican Republic are located. The EPGFZ is named for Lake Enriquillo in the Dominican Republic where the fault zone emerges, and extends across the southern portion of Hispaniola through the Caribbean to the region of the Plantain Garden River in Jamaica.

Eve Systems introduced the EyeTV brand in November 2002. The first device was a small USB-powered device that contained a cable tuner and hardware encoder in order to convert television video into an MPEG-1 format for watching on a computer. It also had coaxial and RCA plugs to connect it with a VCR or camcorder. A 2002 article in Macworld said it was the "first step" in bridging computers and television, but at this point still had "some kinks".

A major advantage of distributed-element circuits is that they can be produced cheaply as a printed circuit board for consumer products, such as satellite television. They are also made in coaxial and waveguide formats for applications such as radar, satellite communication, and microwave links. A phenomenon commonly used in distributed-element circuits is that a length of transmission line can be made to behave as a resonator. Distributed-element components which do this include stubs, coupled lines, and cascaded lines.

According to the original SGI project manager Dan Evanicky, the most common failure items are backlights and power supplies. At this point Dan expects that any power supply in continuous use will have failed, though the monitor itself is likely fine. Monitors left on continuous for a decade or more likely have faded backlights. Generic power supplies work on the unit, specifications are: 3 amps at 12 volts with a 5.5m x 2.5mm center positive coaxial barrel (preferably right angle).

With the convergence of SONET and SDH on switching matrix and network elements architecture, newer implementations have also offered TL1. Most SONET NEs have a limited number of management interfaces defined: ;TL1 Electrical interface :The electrical interface, often a 50-ohm coaxial cable, sends SONET TL1 commands from a local management network physically housed in the central office where the SONET network element is located. This is for local management of that network element and, possibly, remote management of other SONET network elements.

To convert a signal from balanced to unbalanced requires a balun. For example, baluns can be used to send line level audio or E-carrier level 1 signals over coaxial cable (which is unbalanced) through of category 5 cable by using a pair of baluns at each end of the CAT5 run. The balun takes the unbalanced signal, and creates an inverted copy of that signal. It then sends these 2 signals across the CAT5 cable as a balanced, differential signal.

Multipath propagation is similar in power line communication and in telephone local loops. In either case, impedance mismatch causes signal reflection. High-speed power line communication systems usually employ multi-carrier modulations (such as OFDM or Wavelet OFDM) to avoid the intersymbol interference that multipath propagation would cause. The ITU-T G.hn standard provides a way to create a high-speed (up to 1 Gigabit/s) local area network using existing home wiring (power lines, phone lines, and coaxial cables).

Forward echo: In a transmission line, a reflection propagating in the same direction as the original wave and consisting of energy reflected back by one discontinuity and then forward again by another discontinuity. Forward echoes can be supported by reflections caused by splices or other discontinuities in the transmission medium (e.g. optical fiber, twisted pair, or coaxial tube). In metallic lines, they may be supported by impedance mismatches between the source or load and the characteristic impedance of the transmission medium.

Extensive systems can include multiple unit installations with linear amplifiers and splitters to increase the coupling points to a large electrical grid (whether a campus, a high-rise apartment or a community). These systems would typically require coaxial cable interconnection from a transmitter to the linear amplifiers. In the 1990s, LPB, Inc., possibly the largest manufacturer of these transmission systems, designed and supplied several extensive campus-based systems that included fiber-optic links between linear amplifiers to prevent heterodyne interference.

For the gun an APHE and a HE round were available. The specifications of 1937 detailed that the ammunition stock should be no less than a hundred. The gun had an elevation of 23° and a depression of 9°30°°. Optionally coaxial was a Lewis 7.92 mm machine-gun to the left of the cannon that could be decoupled and then was movable within a cone of 30°. It was specially modified, increasing the original 6.5 mm calibre, and called the M. 20 no. 2.

Diplexers are typically used with radio receivers or transmitters on different, widely separated, frequency bands. A single city radio tower might have a police department antenna on 460 MHz and a fire department antenna on 156 MHz. A diplexer at the top combines the two antenna signals to the single coaxial feedline, and a second identical diplexer inside the building separates the feedline signals to the two dispatch radios. Some diplexers support as many as four antennas or radios that work on different radio bands.
|
|
Diplexers are also used in the home to allow a direct broadcast satellite TV dish antenna and a terrestrial TV antenna (local broadcast channels) to share one coaxial cable. The dish antenna occupies the high frequencies (typically 950 to 1450 MHz), and the TV antenna uses lower television channel frequencies (typically 50 to 870 MHz). In addition, the satellite also gets a DC to low frequency band to power the dish's block converter and select the dish antenna polarization (e.g., voltage signaling or DiSEqC).

The station traces its history to May 19, 1945, when television set and equipment manufacturer Allen B. DuMont founded W3XWT, the second experimental station in the nation's capital (after NBC's W3XNB, forerunner to WRC-TV). Later in 1945, DuMont Laboratories began a series of experimental coaxial cable hookups between W3XWT and its other television station, WABD (now WNYW) in New York City. These hookups were the beginning of the DuMont Television Network, the world's first licensed commercial television network. DuMont began regular network service in 1946.

The 2.5 mm or sub-miniature sizes were similarly popularized on small portable electronics. They often appeared next to a 3.5 mm microphone jack for a remote control on-off switch on early portable tape recorders; the microphone provided with such machines had the on-off switch and used a two-pronged connector with both the 3.5 and 2.5 mm plugs. They were also used for low-voltage DC power input from wall adapters. In the latter role they were soon replaced by coaxial DC power connectors.

The Strategic Air Command spent millions of dollars on communication equipment, including the "red telephone" system that connected 200 SAC locations to the command post at Offutt. The need for instant communication made SAC the Bell System's first customer for Touch-Tone dialing. Residential customers also benefited from faster service via coaxial cable and crossbar switching equipment. Since a large amount of equipment had been added to the original Douglas Street building, many of the telephone company's employees were working in leased office space.

For the parallel format, a 25-pin D-Sub connector pinout and ECL logic levels are defined. The serial format can be transmitted over 75-ohm coaxial cable with BNC connectors, but there is also a fibre-optical version defined. The parallel version of the ITU-R BT.656 protocol is also used in many TV sets between chips using CMOS logic levels. Typical applications include the interface between a PAL/NTSC decoder chip and a DAC integrated circuit for driving a CRT in a TV set.

The Sikorsky compound helicopter designs all use coaxial rigid rotors and a pusher propeller, which Sikorsky has collectively named "X2 Technology". On March 25, 2020, the Army selected the Raider X and Bell 360 Invictus concept design candidates to proceed to an eventual flight competition; flying prototypes of each candidate design will be constructed, followed by test flights in 2022 leading up to a competitive flying demonstration no later than fall 2023. Sikorsky had already begun construction of its Raider X prototype by February 2020.

The Centurion crews, after operating for a few weeks in country, soon learned to remove the protective armoured side skirts from both sides of the tank, to prevent the vegetation and mud from building up between the track and the mudguards. Each Centurion in Vietnam normally carried a basic load of 62 rounds of 20 pounder shells, 4,000 rounds of .50 cal and 9,000 rounds of .30 cal machine gun ammunition for the tank commander's machine gun as well as the two coaxial machine guns.

Founded in 1934, Muzak was among the early background music providers. Business audio is produced off-site and delivered to the client via a number of methods including DBS satellite, SDARS satellite, coaxial cable, FM radio subcarrier, leased line, internet broadband, compact disc, and tape. Most audio content is licensed for personal and home use only. Business audio services allow clients to use audio content in public and commercial settings by paying appropriate royalties to performing rights organizations like ASCAP, BMI, SESAC and GEMA in Germany.

To record the signal, he installed a very fast oscilloscope, provided as a prototype by DuMont Laboratories, in an underground bunker several hundred feet from the Gadget, where it was photographed. To bring the signal to the oscilloscope, he devised an oversized coaxial transmission line, whose inner conductor was made smaller as it went from chamber to oscilloscope. Because this configuration enhanced the signal reaching the oscilloscope, there was no need for amplification. To confirm this surprising behaviour, Rossi consulted with Harvard professor Edward Purcell.

Cable television is a system of broadcasting television programming to paying subscribers via radio frequency (RF) signals transmitted through coaxial cables or light pulses through fiber-optic cables. This contrasts with traditional terrestrial television, in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television. FM radio programming, high-speed Internet, telephone service, and similar non-television services may also be provided through these cables. The abbreviation CATV is often used for cable television.

It featured a modern, Israeli-made "glass cockpit" avionics and a turret-mounted folding (for landing clearance) 30 mm cannon instead of the fixed cannon on the Ka-50. It features combat- proven avionics and advanced anti-tank guided missiles for a high level of combat effectiveness. The helicopter has excellent flight performance, and high combat survivability due to its coaxial rotor technology. It is equipped with IAI's flexible modular avionics suite, which can be readily tailored to meet the TLF's operational requirements and provides growth potential.

The Ka-50 and its two-seat version Ka-52 are high-performance combat helicopters with day and night capability, high survivability and fire power, to defeat air targets and heavily armoured tanks armed with air defence weapons. It was designed to be small, fast and agile to improve survivability and lethality. The coaxial rotor design provides a hovering ceiling of 4,000 m and vertical rate of climb of 10 m a second at an altitude of 2,500 m. The rotor blades are made from polymer materials.
|
|
The coaxial-rotor configuration results in moments of inertia values relative to vertical and lateral axes between 1.5 and two times less than the values found in single-rotor helicopters with tail rotors. Absence of the tail rotor enables the helicopter to perform flat turns within the entire flight speed range. A maximum vertical load factor of 3.5 g combined with low moments of inertia give the Ka-50 a high level of agility. Flight systems include inertial navigation system (INS), autopilot and head-up display (HUD).

605–614 Low-pass filters usually consist of series inductors and shunt capacitors. Applying Kuroda's identities will convert these to all shunt capacitors, which are open circuit stubs. Open circuit stubs are preferred in printed technologies because they are easier to implement, and this is the technology likely to be found in consumer products. However, this is not the case in other technologies such as coaxial line, or twin-lead where the short circuit may actually be helpful for mechanical support of the structure.

Daniels' mechanism has since been described by some as the most important development in horology in the past 250 years. Although the horological industry was first introduced to the concept in 1976, Daniels' escapement was met with scepticism and lack of interest. It was not until the 1980s that Swatch Group chairman Nicolas Hayek adopted the concept, using it in his upmarket Omega brand. The company unveiled – to great acclaim – its first automatic watch using Daniels' coaxial escapement at the 1999 Basel Watch and Jewellery Fair.

By the end of 2015, Custom TV packages accounted for between 30 percent and 40 percent of new Fios TV subscribers. Fios TV uses QAM technology to deliver signals to a customer's property using its fiber optic cables. At the home, the optical network terminal turns the signal into a radio frequency signal that can be used on a home's existing coaxial cables, feeding the signal to a set-top box (STB). Fios TV's video on demand and interactive widgets use Internet Protocol technology.

Two similar casemates face south across Vazon beach including one now open as a museum. A Tobruk pit and a casemate for a 4.7cm Pak36(t) anti-tank gun complete the beach-facing defences. In the centre of the headland is a R633 bunker that housed a 5cm M19 automatic mortar. A reinforced field order emplacement, a fortress-quality personnel shelter, a minefield, field positions with trenches and machine gun pits, including a coaxial ball mounted MG 37(t), flamethrowers, and barbed wire completed the strongpoint's defences.

Telstra has provided mobile telecommunications to Ballarat since 2003 (initially as CDMA). Optus provided competition with its entrance to the market in 2003 along with significant service upgrades in 2004 followed by Vodafone in mid-2009. Data communications are provided by several companies. Telstra was the first company to provide dial-up Internet access via the Ballarat exchange, however the first network for broadband Internet access available in the city was a hybrid optical fiber cable and coaxial cable built by Neighbourhood Cable in 2001.

U.FL connectors are commonly used in applications where space is of critical concern, most often Mini PCI cards for laptop computers and WiFi cards. U.FL connectors are commonly used inside laptops and embedded systems to connect the Wi-Fi antenna to a Mini PCI card. Another common use is connecting GPS antennas. Female U.FL connectors are not designed with reconnection in mind, and they are only rated for a few reconnects (approximately 30 mating cyclesSMT Ultra-Miniature Coaxial Connectors - Product Specifications) before replacement is needed.

Through this research Dr. Mosher has discovered that the active tectonic environment is primarily made of breccia, sandstone and siltstone turbidity-current generated debris fans and that faulting, sedimentation and volcanism are merely a small part of plate boundaries. Another of her research projects focused on the partitioning of different types of strain during formation of ductile non-coaxial shear zones in both extensional and contractional environments, including the development of corrugations in metamorphic core complexes and the formation of rods and mullions in thrust nappes.

At microwave frequencies, the types of cable (transmission line) used to conduct lower frequency radio waves, such as coaxial cable, have high power losses. Therefore, to transport microwaves between the transmitter or receiver and the antenna with low losses, a special type of metal pipe called waveguide must be used. Because of the high cost and maintenance requirements of long waveguide runs, in many microwave antennas the output stage of the transmitter or the RF front end of the receiver is located at the antenna.

Modern communication systems multiplex many signals into wideband data streams that are transmitted over optical fiber, coaxial cable, microwave relay, and communication satellites. These wide-band circuits require very fast encryption systems. The WALBURN family (KG-81, KG-94/194, KG-94A/194A, KG-95) of equipment consists of high-speed bulk encryption devices used primarily for microwave trunks, high-speed land-line circuits, video teleconferencing, and T-1 satellite channels. Another example is the KG-189, which support SONET optical standards up to 2.5 Gbit/s.

Porthcurno's association with international telecommunications links continues to the present day. The first successors to submarine telegraph cables were submarine telephony cables of coaxial construction, some of which were landed at Porthcurno. In the last twenty years or so these have all been superseded by their very high-capacity modern descendants, those using fibre optic technology as the transmission medium instead of copper. These also have been landed at Porthcurno forming a significant link, part of the UK connection to the international telecommunications 'backbone' infrastructure.

The same metallization is used for other switch tubes as well.Evaluation of non- cyanide gold plating process for switch tubes, Sandia Report, 1996 Sprytrons are often designed similar to trigatrons, with the trigger electrode coaxial to the cathode. In one design the trigger electrode is formed as metallization on the inner surface of an alumina tube. The trigger pulse causes surface flashover, which liberates electrons and vaporized surface discharge material into the inter-electrode gap, which facilitates formation of a vacuum arc, closing the switch.

The receiver currently installed are as follows : S-Band :The S-Band is a dual polarization band with observable frequencies between 2.2 and 2.37 GHz. The S-Band receiver consists of a choke ring axial corrugated horn designed by the Antenna Group at the Technical University of Madrid. The horn antenna is coupled to a waveguide to coaxial polariser that separates out the two orthogonal components of the incoming circularly polarised beam. The two linear polarisations are then fed directly to two low noise cryogenically cooled amplifiers.

In the late 1980s, Sikorsky Aircraft flew a small UAV named "Cypher", with coaxial rotors inside a torus-shaped airframe. The torus shroud improved handling safety and helped increase lift. The first proof-of-concept Cypher was 1.75 meters (5.75 feet) in diameter and 55 centimeters (1.8 feet) tall, weighed 20 kilograms (43 pounds), and was first flown in the summer of 1988. This design was powered by a four-stroke, 2.85 kW (3.8 hp) engine and was mounted on a truck for forward-flight tests.

This led to the adoption of a waveguide and feedhorn, which were being developed at the same time. Only a few weeks later an even more powerful magnetron arrived, the CV76, which produced 500 kW. In order to deploy the new magnetrons as quickly as possible, it was decided to retain the existing antenna installations and use the CV56 at 70 to 100 kW, ultimately settling at 70. Only the transmitter would be modified with a waveguide, the receiver would continue to use the coaxial feed.

Both sites could have host computers, and backup could be bidirectional. For RDS, the remote adapter emulated the IBM host by producing the channel protocol. The Hyperchannel Trunk was a LAN made of up to four parallel coaxial cables carrying 50 Mbit/s, which, at the time, was considered bleeding-edge technology. There could be many adapters on the trunk, so that, for example, mainframes of different types could inter-communicate across the trunk network that could also have an adapter for telecomms links to other locations.

The gun could fire a wide range of ammunition but the most commonly loaded types were high explosive squash head (HESH), armour-piercing discarding sabot (APDS), or practice round equivalents for both types. The Chieftain could store up to 64 projectiles (though a maximum of 36 APDS, limited by the propellant stowage). The gun was fully stabilised with a fully computerized integrated control system. The secondary armament consisted of a coaxial L8A1 7.62 mm machine gun and another 7.62 mm machine gun mounted on the commander's cupola.

The very first HFC networks, and very old unupgraded HFC networks, are only one-way systems. Equipment for one-way systems may use POTS or radio networks to communicate to the headend. The return-path or upstream signals carry information from the home to the headend/hub office, such as control signals to order a movie or internet upstream traffic. The forward- path and the return-path are carried over the same coaxial cable in both directions between the optical node and the home.

These early twin-turret tanks were nicknamed "Mae West" by the troops, after the popular busty movie star. The twin-turret layout was inefficient, but was a common feature of 1930s light tanks derived from the Vickers, such as the Soviet T-26 and Polish 7TP. An improved version of the M2 Light Tank, the M2A4, armed with a high-velocity 37 mm gun M3 and coaxial machine gun in a single turret, served with the Marines' 1st Tank Battalion on Guadalcanal in 1942-43.

Originally designed for the British Army, the Scorpion Armoured Reconnaissance Vehicle began production in the early 1970s, and was in use with the Irish Army from 1980 until 2017. The army bought 4 Scorpions each year from 1980 to 1982 plus 2 more in 1985 bringing the total in Irish service to 14. The Scorpion had three crew members and a maximum speed of 70 kilometres per hour. In Irish service, it was primarily armed with a 76mm rifled gun and a 7.62mm coaxial mounted machine gun.

The CEBus standard was released in September 1992. CEBus is an open architecture set of specification documents which define protocols for products to communicate through power line wire, low voltage twisted pair wire, coaxial cable, infrared, RF, and fiber optics. The CEBus Standard was developed on the foundation of an IR (infrared) protocol developed by GE (General Electric). This work was transferred to the EIA at the beginning of the EIA's involvement, under the plan that it would be expanded then maintained by the EIA.

The terminal allowed the user to work on one page at a time, which was periodically saved to the minicomputer. This "intelligent workstation" concept for word processing was similar to the functions of popular systems from rival Wang Laboratories. Prime's intelligent workstation for word processing was faster because it used RS232C cabling runs instead of the coaxial links that Wang's systems used. Nonetheless, the word processing was not of the highest quality, and the PT65 was subject to software errors that scrambled the documents being worked on.

The propfan engine had coaxial contra-rotating propellers, with the front and back propellers (supplied by Hamilton Standard) each containing six blades of in length. The propellers had a recommended tip speed of , and the engine could support a maximum aircraft flight speed of Mach 0.80–0.82. 44 percent of the engine's torque would be handled by the front propeller, while the other 56 percent would be absorbed by the back propeller. The hot gas exhaust contributes just two to three percent of the total thrust.

This function affords the cable company the ability to add or delete descrambling on the channels that come in through the coaxial cable line. It also allows them to remotely disable the box, for reasons such as non-payment of the cable bill or theft of the unit itself. Such commands are referred to as bullets and are a transmitted message which affects the cable box program effectively disabling or "killing" it. "Bullets" do not affect the electronics inside converters or descramblers, only the programming.

In the midst of the 1920s, coax was applied to telephone networks as inter-office trunks. Rather than adding more copper cable bundles with 1500 or 1000 pairs of copper wire and cable in them, it was possible to replace those big cables with much smaller coaxial cable. The next major use of coax in telecommunications occurred in the 1950s, when it was deployed as submarine cable to carry international traffic. It was then introduced into the data processing realm in the mid 1960s.

The chain drive sprocket was coaxial with the swinging arm pivot, an arrangement to keep the drive chain tension constant, irrespective of the movement of the swinging arm. The alloy wheels, anodised either gold or black, were neither forged nor cast, but were made up from two sheet alloy pressings, riveted together. The frame was available either painted black or nickel-plated. Subsequently, the V1000 received several updates to address early problems, including digital engine management, and modification to suspension, brakes, wheels, engine and gearbox.

The RCA Satcom domestic communication satellite launched on December 13, 1975, spurred the cable television industry to unprecedented heights – with the assistance of HBO. In the Fall of 1974, executives from Time Inc. and the Home Box Office unit began conceptualizing ideas to expand HBO into a national pay television service. Developing a vast infrastructure of microwave and coaxial telephone relay towers in all 50 states and U.S. territories would have been cost-prohibitive for Time/HBO due to the time and expense involved.

These few short wire elements serve to receive the displacement current from the driven element and return it to the ground conductor of the transmission line, making the antenna behave as if it has a continuous conducting plane under it. Often (see pictures) the ground plane rods are sloped downward, to lower the main lobe of the radiation pattern closer to horizontal and increase the normal 36.8 ohm radiation resistance closer to 50 ohms to provide a better impedance match with standard 50 ohm coaxial cable feedline.

Bowen finalized plans to build the ASV radios at EKCO using the new VT90 tubes (later known as CV62) in the transmitter, while the AI Mk. II would use the older DET12 and TY120s. This meant the ASV would be somewhat more advanced than AI. Another chance encounter after the meeting led Bowen to try a new material, polythene, from Imperial Chemical Industries (ICI) which produced excellent coaxial cable and neatly solved the electrical problems they had been having. It was soon in use throughout the industry.

Heavy Industries were established with Ukrainian assistance mainly to assemble the BTR-3U fleet of the Myanmar Army. Total of 1,000 BTR-3U wheeled APCs are to be assembled in Burma over the next 10 years from parts sent by Ukraine. The BTR-3U is fitted with a number of modern weapon systems including 30 mm gun, 7.62 mm coaxial machine gun, 30 mm automatic grenade launcher and anti-tank guided weapons. HI has also built APC/IFV such as MAV 1, MAV 2 and BAAC APCs.

The turret is the Italian Oto Melara T60/70A which is normally armed with a stabilized 60 mm rifled autocannon, a 7.62 mm coaxial machine gun and 12.7 mm anti-aircraft heavy machine gun. Inside the turret are the stations of both the gunner and the commander. The 60 mm autocannon can be replaced by a variety of guns from 25 mm autocannons to 105 mm guns. The turret is equipped with two clusters of four electrically operated smoke grenade launchers on each side.

An electronic oscillator can be made from a klystron tube, by providing a feedback path from output to input by connecting the "catcher" and "buncher" cavities with a coaxial cable or waveguide. When the device is turned on, electronic noise in the cavity is amplified by the tube and fed back from the output catcher to the buncher cavity to be amplified again. Because of the high Q of the cavities, the signal quickly becomes a sine wave at the resonant frequency of the cavities.

The TOP-1 telescopic sight is to the left, and the coaxial DT tank machine gun and PT-K commander panoramic sight is to the right. Parola Tank Museum in Finland. The T-26 Model 1933 carried 122 rounds of 45 mm ammunition, firing armour-piercing 45 mm rounds with a muzzle velocity of , or lower-velocity high-explosive munitions. Tanks intended for company commanders were equipped with a radio set and a hand-rail radio antenna on the turret (so called "radio tanks").

|
As in a klystron, each bunch passes into the cavity at a time when the electric field decelerates it, transforming the kinetic energy of the beam into potential energy of the RF field, amplifying the signal. The oscillating electromagnetic energy in the cavity is extracted by a coaxial transmission line. An axial magnetic field prevents space charge spreading of the beam. The collector electrode is at a lower potential than the anode (depressed collector) which recovers some of the energy from the beam, increasing efficiency.

A waveguide rotary joint is used in microwave communications to connect two different types of RF waveguides. Because coaxial parts are symmetrical in ø direction, free rotation without performance degradation is accomplished. In the rotating part, electrical continuity is achieved by λ/4-chokes eliminating metal contacts. The Rotary Joints can have both waveguide ports at a right angle to the rotational axis, "U-style", one waveguide port at a right angle and one in line, "L-style" or both waveguide ports in line. "I-style".

Frequency-division multiple access (FDMA) is a channel access method used in some multiple-access protocols. FDMA allows multiple users to send data through a single communication channel, such as a coaxial cable or microwave beam, by dividing the bandwidth of the channel into separate non-overlapping frequency sub-channels and allocating each sub-channel to a separate user. Users can send data through a subchannel by modulating it on a carrier wave at the subchannel's frequency. It is used in satellite communication systems and telephone trunklines.
