F-Type Connectors

F Type
The F-Type connector series is a durable, high performance threaded interface. Primary applications of the F-Type connectors are for cable television (CATV), set top boxes and cable modems.

Amphenol RF’s F-Type is a 75 ohm product designed for a wide range of coaxial cable with 0.022-0.042 in. diameter center conductors, and complies with a 3/8-32 thread specification.

The F-Type connector is a threaded alternative to the slide-on G-Type connector.
