An F connector, or F-type connector, is a coaxial connector which is commonly attached to an RG6 or RG59 cable and transfers an electrical signal for terrestrial TV or satellite television. They are threaded connectors which have a maximum operating frequency of 1 GHz and impedance of 75 ohms and are used to help make a connection in coaxial cables.

Where are F Connectors used?

F connectors are mostly used in domestic environments for cable, terrestrial and satellite TV installations, due to the fact that very high frequencies are involved. Although F connectors are not weatherproof, they can be enhanced with an O-Ring providing some weatherproofing.
