This antenna is designed for use as a clamp mount to the air dam shield or flap of long-haul trucks, RV's or similar installation. This antenna can also be mounted to any flat surface able to accommodate a clamp-style mount bracket. For best performance, the black antenna housing at the top of the mast should be installed above any other truck parts for an unobstructed view of the sky in all directions with a clearance of 20 degrees. Please click on the product manual below for full installation instructions. This antenna is designed for single antenna lead XM Satellite Radio receivers. It may also be used with older dual antenna lead receivers with the addition purchase of the dual input splitter.
