Male F Connector
The F connector is a type of 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. It was invented by Eric E. Winston in the early 1950s while working for Jerrold Electronics on their development of cable television.
The F connector is inexpensive, yet has good 75? impedance match up to 1GHz and has usable bandwidth up to several GHz. One reason for its low cost is that it uses the solid conductor (center wire) of the specified types of coaxial cable as the pin of the male connector. This design is subject to the surface properties of the inner conductor (which must be solid wire) and is not corrosion resistant, hence water proof versions are needed for outside use (for example, on aerials). The male connector body is typically crimped, or sometimes screwed, onto the exposed outer braid. The cable industry standard now is to use compression fittings. 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 (e.g., a nearby TV transmitter will interfere with a CATV station).
It is suitable for domestic terrestrial, cable, and satellite TV installations and offers significant improvements over the Belling-Lee connector used on European terrestrial receivers. It requires slightly more care to properly install the male connector to the cable than with Belling-Lee type and attention should always be paid to the quality of the connector and matching with the cable size.
