The UHF connection is by far the most popular type used in Amateur Radio. The UHF male (plug) is known as "PL-259" and the female (jack) is known as "SO-239." Typically used in applications to ~400MHz.
Type F connections are commonly known for use in "over the air" television, cable television, satellite television, and cable modems. The commonality of Type F connectors found in televisions has reigned since the 1960's and was later used UHF applications. Type F connections are 75 ohm and are used in applications up to ~1 GHz. Type F connectors are also referred to as F-81 connectors, F-Type connectors, Type F connectors, cable TV connectors, Satellite connectors, and TV connectors. Type F Connectors are commonly misidentified as mini-UHF connectors. Be sure to look closely at the features of the males and females to tell the differences.
