Coaxial cable, also known as coax or coaxial line, is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. The word "coaxial" refers to the inner and outer conductors (or paths of current flow) being axially aligned. Coaxial cables are able to transmit radio frequency signals with very low transmission losses over a broad range of frequencies. This makes them ideally suited to carrying cable television signals, broadband internet, and radio frequency sounds and television audio.
