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.
Developed by the Radio Corporation of America (RCA), the RCA connector is used in several video and audio applications. This connector is sometimes referred to as a Phono Plug. This is due to the fact that the connector's original purpose was to connect RCA phonograph players to an amplifier. The RCA connector is not, by its very nature, a 75 Ohm design. However, it is used in a multitude of 75 Ohm applications.
