F connector
Encyclopedia : F : FC : FCO : F connector
The F connector is a type of coaxial RF connector commonly used for 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-ohm impedance match up to 1 GHz. One reason for its low cost is that it uses the center wire of the coaxial cable as the pin of the male connector. While lowering cost, this design drastically reduces the long-term reliability compared to other connectors, the copper wire being extremely prone to corrosion. The male connector body is typically crimped, or sometimes screwed, onto the exposed outer braid. Female connectors have a 3/8-32 thread. Most male connectors have a matching threaded connecting ring, though push-on versions are also available. Push-on F connector ends provide poor shielding against airborne signals (for example, a nearby TV transmitter will interfere with a CATV station).
