Coaxial cable, also known as TV aerial cable or coax, is primarily used to carry video and data signals from an aerial to a device such as a satellite dish or television. This is due to the well-insulated conductor wire which prevents frequency interference. Although they are often referred to as satellite cables for the transmission they are typically used for, they can also be used in computer networks. Aerial cable is available in a wide range of lengths and sizes to suit any installation requirements.
