Explanation
RG (Radio Guide) designations are standardized ratings for coaxial cables. RG-59 is a coaxial cable type commonly used for analog video, CCTV, and older cable TV installations. Other common coaxial designations include RG-6 (standard cable TV and satellite) and RG-8/RG-58 (radio/networking). Coaxial cable has a central copper conductor surrounded by insulation, a metallic shielding layer, and an outer jacket. It is not fiber optic (which uses light), twisted pair (which uses paired copper wires), or plenum (a jacket material classification).
