RG-6
Updated: 10/17/2017 by Computer Hope
RG-6 describes coaxial cables that send and receive sound and video signals and are the most common method for transmitting cable television. Standard RG-6 cables have an 18 AWG (American Wire Gauge) center conductor and 75 ohm characteristic impedance. They can have several connectors, including an F connector, a BNC (Bayonet Neill-Concelman) connector, and RCA plugs.
There are three types of RG-6 cables: plain or house, flooded, and aerial or messenger. Each is designed for use in different environments. Plain or house is used for wiring inside or outside a house. Flooded is used for underground burial or inside buried conduits, and aerial or messenger for use in above ground drops from utility poles.
