A dome mount is the perfect solution for creating a permanent, rock-solid CB antenna mounting surface that can accommodate antennas up to 5' tall, including fiberglass and medium-sized trucker antennas like the Wilson 2000. If you'll be removing a headliner for installation, you may want to consider the lug-style version of this mount, the Firestik DM4 Mount (see related products). The DM4's coax connection takes up much less space and is more suitable for tight headliner installations.

As you would expect, Firestik takes the popular dome mount to the next level! Instead of using a multipiece mold insert, Firestik designed its mounts with a one-piece insert. This eliminates the chances of developing internal resistance or water leaks through the center that can corrode connections or ruin the inside of your vehicle. Firestik molded this piece using glass-reinforced nylon for durability, strength and longevity.

The dome mount is made to fit a standard 1/2" (13mm) hole, so you can use it 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 and 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.
