What is the best antenna for off-road vehicles (jeeps, UTV’s, dune buggies) using GMRS, or General Mobile Radio Service? The GMRS frequency ranges between 462-467 MHz and is excellent for off-roaders looking to stay in touch out on the trails. These antennas ideally utilize a metallic “ground-plane” of at least 1x1 feet (like the roof of a truck) but in the off-road world that usually is not possible. Most GMRS antennas get mounted on fenders, bumpers or spare tire hitches.
So, how can overcome this? Easy, you can use an NGP or No Ground Plane required antenna. We have found that the best antenna for GMRS radios where little to no metallic ground plane is available are the Laird – Antenex B4505CNS (chrome) and BB4505CNS (black) antennas. These are only about 32 inches long, and operate at 5 db gain and have a spring base so they don’t get easily damaged in the wild. These are NMO mounted and are typically IN STOCK at all times. I hope this helps!
