This weBoost mounting kit includes a 3/8"-24 x .375" threaded RAM® Tough-Ball™ that screws into thread adapter of the weBoost antenna, a C size short length socket arm and a C size medium clamp RAM® Tough-Claw™ to mount to 1" to 1.6" rails and bars such as a vehicle ladder, or roof/bed rack. The adjustability of the RAM® Mounts system allows you to collapse the antenna while not in use, as well as extend the reach of the weBoost antenna if mounted in a tight space. This weBoost antenna mount is compatible with Drive Reach OTR and Drive X antennas making this the ideal mounting solution for off-road vehicles and semi-trucks.
