F Type Coaxial Connectors
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 RG6/U cable or, in older installations, with RG59/U cable . The F connector is inexpensive, yet has good 75 Ω impedance match up to 1 GHz and has usable bandwidths 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.
