military specifications as it was originally a unit indicator for bulk radio frequency. RG actually stands for “Radio Guide” and derives from World War II, The RG Cable was used for U.S. The RG Cable has come a long way and evolved in significance since its days of initial use. Although there are a handful of coaxial cables, a frequently appearing cable type in a home and residential settings is the RG-6 Cable. What makes these coax cables unique among other shielded cables is the ability to function as transmission lines by controlled cable dimensions with constant conductor spacing.Ĭoax cables are default cables of their type and are compatible with most daily use electronics. The name “coaxial” came about from the inner conductor and outer shield sharing one geometric axis. Invented by Oliver Heaviside, coaxial cables are electrical copper-based wire cables with inner conductors surrounded by a tubular insulating layer then wrapped together by a metallic shield and often a synthetic outer jacket, as well.
