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.

3/8 x 24 connections are a common type for mobile antennas and mounts. 3/8 x 24 Adapters are commonly misidentified as a hardware type, but superior material use makes for better connections.
