RG 6 Cables
Made with either a copper clad steel (CCS) or bare solid copper (BC) center, RG-6 cables are probably the most common coax cable, as they are used to relay cable television signals. Derived from the WWII military-specification “Radio Guide,” they are available in four different application-specific variations:
Plain — For standard indoor/outdoor house wiring.
Flooded — Contains an additional water-blocking gel for underground conduits.
Messenger — Contains a steel wire to bear the tension of the aerial drop of a utility pole.
Plenum — Surrounded by a Teflon-based outer jacket to meet the fire codes of ventilation ducts.
