Coaxial cables was designed back in the 1880’s, however their unique construction which involves an inner copper core conductor with an insulating layer which is then surrounded by a tubular conducting shield and an insulating outer layer has assisted in the longevity of this product. Coaxial cables can be found pre-wired in many homes today and cable companies profit everyday from its development. Coaxial cables are used for cable TV signals, computer network connections and radio frequency signals. The common use of coaxial cables is due to the fact that the cable can provide protection of a signal caused by electromagnetic interference from the development of an inner and outer conductor. Coaxial cables may be installed next to gutters and other metal objects and still provide a high quality signal.
