FireStik Stainless Steel Disc mounts are a basic flat surface mount for use on any trunk or roof antenna installation.

The FireStik 2.5 inch circular disk mount is recommended for use any FireStik (FS) or FireStik II (FS2) antenna up to 3 feet tall and FireFly (FL) antennas up to 4 feet tall.

The K-4DD mount features a low underside profile for ease of installation in tightly confined spaces. A ½ inch mounting hole on a flat surface are all that is needed to install the FireStik stainless Steel antenna disc mounts. Nothing fancy required.

When installing any ground plane antenna the bottom disk must make solid contact with a suitable chassis ground. The FireStik K-4DD and K-4ADD are extremely strong mounts and are designed to provide years of trouble free use with any two-way radio antenna and accessory that feature a 3/8x24 threading.

Be sure to select either the K4DD with terminal connector or the K4ADD with SO239 connector to correctly match your coaxial cable connection when placing your order with CB World your number one shop for CB radios and antennas anywhere.

FireStik Disc mounts are compatible with any antenna that has a 3/8x24 ferrule

FireStik recommends using 18 feet of high quality RG58 CB coax with their antenna mounts and antennas

The mount worked out perfect for my situation it has a nice large washer to provide great support for the entire load of the antenna. Will be buying more to provide a nice clean and sealed install of a antenna on my equipment.
Perfect...everything I expected and works great...nothing negative to say
