Instead of using a multi-piece mold insert we designed our mounts with a one piece insert. The chances of developing internal resistance is totally eliminated as is the possibility of having water leak through the center to corode connections or ruin the inside of your vehicle. We also molded this piece using glass reinforced nylon for durability, strength and longevity. Fits 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. 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 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.
