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

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.
