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 RAM® Diamond Ball base for flat surface drill-down mounting such as a rear bumper, spare tire carrier, or antenna bracket. 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 the Drive Reach OTR and Drive X antennas making this the ideal mounting solution for off-road vehicles and semi-trucks.
