F connector. From Wikipedia, the free encyclopedia. The F connector is a coaxial RF connector commonly used for over the air terrestrial television, cable television and universally for satellite television and cable modems, usually with RG-6/U cable or, in older installations, with RG-59/U cable.
These connectors are generally used with audio and audio-visual (AV) equipment, and are solely for use with unbalanced signals. The connectors are colored according to the signal type. The white connector is used for sending signals to the left (L) channel, and the red connector is used for sending signals to the right (R) channel.
