The Coaxial Cable is the typical cable used for TV antennas. It gets its name because of the two interior concentric cables: one is made from copper and transmits information and the other outer cable is in the shape of a tube, which can be made from copper or aluminium, and serves at the earth connection. Both are separated by a layer of insulated material.
The applications of the coaxial cable are varied and it's used, aside from connecting antennas to televisions, for urban internet and TV cable networks, for telephone lines or for distributing video signals. At LEDKIA, we have rolls of coaxial cables from 50 to 300 metres at an incredible price.
