This antenna mount is designed for the Freightliner Cascadia mirror arm. This "bird perch" type mount utilizes a single bolt on the drivers side mirror, simply remove one of the 4 bolts that holds the mirror onto the door and screw this mount in it's place. Typically used with CB and HAM radio antennas. We suggest a top loaded fiberglass antenna like the Firestik FS5 with this mount. Works with P4 and P3 Cascadia Trucks.
No matter what I did short of lock tight it wouldn't stay tight on the passenger side.

This mount is designed specifically for the Driver's side. If it's installed on the passenger's side, the bolt will unscrew. The only way to prevent this on the passenger's side is to use Loctite combined with the included jam nut.

Easy installation. Works well with Sirius/XM antennas.Because this mounts on the passengers side, the wind is constantly trying to un-screw the mount. Consider adding loc-tite to keep this mount in place.A good way to mount your Sirius/XM Antenna on your Freightliner Cascadia. Mounts above the passengers side door by removing an existing bolt and screwing this mount in.
