The F connector (also F-type 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 with RG-59/U cable.

The F connector was invented by Eric E. Winston in the early 1950s while working for Jerrold Electronics on their development of cable television.[1] In the 1970s, it became commonplace on VHF, and later UHF, television antenna connections in the United States, as coaxial cables replaced twin-lead. It is now specified in IEC 61169-24:2019.[2]
