Coaxial Cables

Coaxial cable (or "coax") is the most common cable used for transmitting video signals. The name "coaxial" refers to the common axis of the two conductors.

Construction

A coaxial cable has a solid copper or copper-clad-steel centre conductor surrounded by a non-conductive dielectric insulating material. The dielectric is surrounded by foil shield/s and/or copper braid/s which form the outer conductor and also shield against electromagnetic interference (EMI). The outer conductor/shield is encased in a PVC/PE jacket.

Most coaxial cables for video applications have a nominal impedance of 75/50 ohms. Their differing electrical and physical characteristics make it important to select the correct type of cable to suit the application. 

Coaxial cables that conform to U.S. Government specifications are identified with an RG designation.
The meaning of the individual components of the designation are:

If the letters A, B or C appear before the slash (/) it indicates a specification-modification or revision. As an example, RG 8/U is superseded by RG8A/U.

The three most commonly used coaxial cable types for video applications are RG59/U, RG6/U and RG11/U.
