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.

Thus, the male connector consists of only a body, which is generally crimped onto or screwed over the cable shielding braid, and a captive nut, neither of which require tight tolerances.

[4] Push-on (aka Flex) F connectors provide poorer shielding against microwave signals of high field strength.

Nearby television, FM radio, mobile & cordless phones, government radiolocation (54–1,002 MHz)[5] transmitters can potentially interfere with a CATV or DTH Satellite reception or operation if the Flex connector is poorly installed.
