Twist-On F Type / F Connector (Use with RG6U Coax cables)
The F connector is a common means of connecting television signals. It 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.

Used this connector with RG59 or RG6U cable as below
The F connector is inexpensive, yet has good 75 Ω impedance match up to 1 GHz 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.
