The bracket is fixed on the strut, and the steel cable is connected to the sliding sleeve on the strut. The strut is inserted into the user support rod. The antenna vibrators are paired in pairs and fastened on the outside of the two main rods by the clamping frame. The high-frequency coaxial cable passes through the main rod. There is a sealing plug at the joint to seal and inner, and the outer conductor connector connects the cable shielding wire and core wire with the main rod wall.
