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.
The F connector is inexpensive, yet has good 75 Ï impedance match up to 1 GHz and has usable bandwidth up to several GHz. One reason for its low cost is that it commonly uses the solid conductor (center wire) of the specified types of coaxial cable as the pin of the male connector.
