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.

The SMA connection is a threaded, tight locking, subminiature type. The SMA connection’s threads ensure a perfect connection allowing use at higher frequencies: ~18 GHz.
