For increased radio range, the black Midland 3 dB Highland Heavy-Duty Bullbar Antenna with Spring Base and Cable easily mounts on a 0.5" hole on your vehicle. Built using durable fiberglass, this antenna extends your range in wide open spaces, highways, cities, dense forests, and mountains. The antenna itself is strong enough to handle tough terrain and trails, and the included spring-base makes this antenna suitable for dense paths and off-road trails. The included 19.5' coax cable allows you the freedom to mount your antenna virtually anywhere on your vehicle.
