This double-grove CB antenna mount has multiple applications that make it a popular aluminum mount. The versatility of this mount paired with its affordability makes it the choice for many CB users.

The two-piece bracket is heavy duty aluminum. Both halves have a horizontal 1/4" groove that allows mounting on wider bars and posts than other antenna mounts. The halves are connected by four 1 1/2" bolts. With the existing bolts the mount can be attached to horizontal posts up to 1" thick or vertical posts up to 3/4" thick. The overall height of the bracket without the stud is 2 7/16". The stud adds about 1 3/16" more to the height. It is 2" wide and 2 1/4" deep. The stud is a standard 3/8" x 24 threaded stud with an SO239 (female to the PL259) connector for the coax.

This mount has several applications. It can be used for mounting on mirrors or any horizontal or vertical post. By removing the back plate, you can use it to mount to any flat, vertical surface. We have seen these mounted on the sides of RV's, tool boxes on pickups, the inside edge of a pickup bed, mirrors, bird perch mounts, etc.


  • Heavy duty aluminum mount
  • Heavy stud with SO239
  • Double grove design
  • Mounts on up to 1" thick posts


A CB coax with PL259 connectors (big screw-on connectors) is recommended for this mount.


This is a heavy mount that can hold just about any antenna. Just be sure the post you are attaching the mount to can hold the weight! This mount accepts 3/8 x 24 threaded CB antennas. A CB antenna spring is recommended for this mount.

These mounts are sold in bulk, which means they are packed and shipped several in a box with no packing material. As a result, they tend to been a little roughed up. Most of these mounts will have scratches and dents. If you are looking for something more polished, have a look at our Firestik 3 way mounts.
