What is a coaxial or coax cable? If you've ever had a home entertainment system installed, odds are you've seen one of these electrical cables before. Coax cables are often used by cable TV companies to connect their satellite antenna networks to your home or business. 

A coaxial cable is made up of an inner conductor, which is a copper core, contained within a dielectric insulator which is in turn encapsulated by a woven copper shield; all of this is then further protected by an outer plastic sheath. Though it can be considered a shielded cable, or a cable resistant to EMI or electromagnetic interference, the dimensions of the cable and connectors are controlled primarily for the precise conductor spacing it requires in order to act efficiently as a transmission line.
