Designed to hold most VHF and similar antennas. The mount will work with any standard antenna that has a 1" -14 threaded interface. A patented rubber ball and socket system securely mounts the antenna while allowing for almost infinite adjustment. Mount the antenna on a horizontal or vertical surface or anywhere in between. The ball base is made from a light weight marine grade aluminum with powder coat. The ball socket and male 1" -14 threaded post are made from high strength composites designed for prolonged outdoor use.
