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. This allows coaxial cable runs to be installed next to metal objects such as gutters without the power losses that occur in other types of transmission lines. Coaxial cable also provides protection of the signal from external electromagnetic interference.

Cables House Supplies wide range of Coaxial Cables and we are the stockist of following types of communication cables.   Coaxial cable is a cylindrical cable that is composed of an inner core, insulator, shield and outer cover. It is commonly used to connect antennas with radio transmitters and receivers for cable internet connections, cable television distribution systems, etc

Rigid Coaxial Cable

A coaxial cable is a higher-grade cable designed to meet specific impedance and to carry higher quality signals, which can be operating at higher frequencies and data rates. A coaxial cable contains two conductors, which are centered on the same axis. Within a coaxial cable is an inner conductor for the signal usually made from copper surrounded by a dielectric material. The center conductor and insulator are surrounded by the shield or ground conductor and an insulating outer sheath or jacket.

The spacing between the outer ground to the inner conductor is important to maintain throughout the length of the cable. The ratio of the inner conductor diameter to the outer ground shield and the dielectric material are parameters and properties that determine the cable’s characteristic impedance. The characteristic impedance is what determines whether a high-frequency signal is effectively passed through a cable with little degradation or not.

What is a coaxial cable used for?

Coaxial cables are often used for radio frequencies and radio transmission, feed lines to antennas, Internet, digital audio, and cable interconnects. They are now found in high-end electronic test equipment, where high frequency signals are being probed. They are often used in network analysis, interfacing with a vector network analyzer and networks of interest.

RG58

RG58 is a common cable used for 50 ohm applications, measuring 20 awg. Today it is mostly used on devices that need only audio or video instead of both, like a HAM radio or security camera.

RG8

RG8 is a thicker 50 ohm cable, at 12 AWG, that can provide a stronger signal than RG58. It is mainly used for amateur radio. There is also a version called RG8X, which is thinner at 16 AWG but provides similar signal quality.

RG59

RG59 is the 75 ohm alternative to RG58, also measuring 20 AWG. It used to be used for cable television but has largely been replaced by newer, more effective coax cables.

RG6

RG6 is the successor to RG59, measuring at 18 AWG. Also a 75 ohm cable, RG6 is better shielded and carries HD signals for greater distances. Currently, this is the standard cable used for cable television, satellite television, and cable internet modems.

RG11

RG11 is another 75 ohm cable that is thicker than RG6 at 14 AWG. The thickness makes it less flexible but ideal for long runs. It is commonly used in place of RG6 when distance is an issue.

RG174

RG174 is a thinner variant of 50 ohm cable at 26 AWG. Its thinness provides extra flexibility but signal loss is higher compared to RG58. This cable is most commonly used for Wi-Fi pigtails.

RG178

RG178 is also 50 ohm and used for high-frequency signals, with a maximum attenuation of 42.7 @ 900 MHz (almost double the max attenuation of RG174). This cable is very thin at 30 AWG, making it best for short distance runs.

RG213

The RG213/U Coaxial Cables are commonly used for Internal wiring of mainframes, communication instruments, and electronic devices as well as connection of test head and interface of IC test system.

RG214

The RG 214 has excellent attenuation stability. The silver-plated outer conductor prevents oxidation of the conductors thereby minimizing attenuation change vs time. Conversely, bare copper outer conductors may oxidize quite rapidly precipitating loss increase.

RG316

RG316 is an alternative to RG178. RG316 is twice the size of RG178 at 26 AWG, giving it half the attenuation but also cutting down on signal loss.

LMR CABLES

LMR-100

LMR-100 is very thin, being designed to replace RG-174. It possesses more than double the shielding of RG-174, cutting down on signal loss significantly.

LMR-195

LMR-195 was made as a replacement for RG58. With superior shielding, signal loss is decreased anywhere from 20% to 33% depending on the distance of the cable.

LMR-200

LMR-200 also replaces RG58 and has the same 0.195” OD as LMR-195 cable. The difference is that LMR-200 has a slightly thicker center conductor, allowing it to cut down on signal loss a bit better than LMR-195.

LMR-240

LMR-240 was made to replace RG8X. Signal loss using LMR-240 is 35% to 64% less than RG8X, with fluctuations depending on the overall distance the signal travels.

LMR-400

LMR-400 is arguably the most common LMR cable, being a replacement for RG8. There is also a version called LMR-400 75 ohms, the only LMR cable capable of running at 75 ohm.

LMR-600

LMR-600 was not made to act as a replacement to RG coax like the other LMR cables. Instead, it was built to be a very thick and powerful cable for long distance runs. LMR-600 is primarily used for powerful satellite frequency transmissions, being able to run signals from 31 to 153 meters.
