| As you would expect, Firestik takes the Dome Mount to
the next level! Instead of a multi-part insert that can develop high resistance,
and not be accessible for repair, our insert is now one solid piece. It is
impossible for it to have any develop internal resistance or worse, opens. We
also molded this piece using glass reinforced nylon for durability and
longevity.
Both models are made to mount in a standard 1/2" (13mm)
hole so you can use them on all common mounts (mirror mounts, flat mounts, stake
hole mounts, etc.) or by itself as a stand alone mount. Each model includes a
rubber seal as well as an underside support washer. These mounts have a 2"
(51mm) diameter base, and when installed with the rubber seal in place, stand a
little over 2" (52mm) tall. The major difference in the two models is the method
of connecting the coax cable.
The DM-4A requires that the coax cable be terminated with a PL-259 connector on the mount end as well as on the radio end. While this adds convenience to the installation, it also requires more space on the underside, about 0.95" (24mm) not including the space added by the connector.
