A mount attaches your antenna to a cable, that in turn connects to your mobile radio. Surface mount antennas are permanent and require a hole to be drilled in your vehicle. Magnetic mounts can be easily removed. The cable can be seen with a magnetic mount, where it is hidden on a surface mount.
Since the cable must be attached to the radio, it's important you get the correct connector type. Most mobile radios require a PL259 style connector to connect to the radio.
However, a few require a Mini-UHF. See our selection of mounts for mobile radio antennas is below.
