Easily elevate your booster’s antenna with this 18-inch mast extension—ideal for trucks, overland setups, and sprinter vans. Designed to rise above rooftop tents, gear racks, and other equipment, it helps maintain strong, uninterrupted cell signal. This extension replaces the standard 13-inch mast included in the Drive Reach Overland, RV, or OTR kits. Note: it cannot be combined with the original mast extension.
