CB Antenna Stud Mount
Dome Mount With Lug Connector
As you would expect Firestik takes the popular dome mount to the next level! We make the worlds best! 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. Made to fit a standard 1/2" (13mm) hole so you can use 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-4 requires coax cables that are terminated with ring terminals. We supply the necessary ring terminals with the mount. This style has a very low profile on the underside which makes it idea for vehicle roofs with headliners. Total space consumed on the underside by all components is a mere 0.675" (17mm).
