Short for Radio Guide, RG is a designation for different types of coaxial cable, which is a type of wire that consists of a center wire surrounded by insulation and then a grounded shield of braided wire. The RG specification is a older military-initiated specification. RG-6 is one of the most commonly used coaxial cables for residential and commercial applications, and is also the standard CATV used to route home cable television.
