Background

Coaxial cables, which are a type of cable that is surrounded by a conductive shield surrounded by a coaxial jacket by an inner conductor, and by two dielectrics (insulating materials) that are separated, many also have a protective outer jacket or sheath. The term "coaxial" refers to an inner conductor and an outer shield that share a geometric axis, and a coaxial cable is a transmission line for transmitting high frequency electrical signals with low loss. It is used in telephone trunks, broadband internet cables, high-speed computer data buses, cable television signals, and applications where radio transmitters and receivers are connected to antennas. It differs from other shielded cables in that the dimensions of the cable and connector are controlled to provide a precise, constant conductor spacing necessary to make it function effectively as a transmission line, and in that the coaxial cable functions as a transmission line for radio frequency signals. Its applications include feeder lines connecting radio transmitters and receivers to antennas, computer network (e.g., ethernet) connections, digital audio (S/PDIF), and distribution of cable television signals. One advantage of coaxial cables over other types of radio transmission lines is that in an ideal coaxial cable, the electromagnetic field carrying the signal is only present in the space between the inner and outer conductors.
