What is the Best Antenna for GMRS Radios for Off-roading?

Posted by Michael Crudele on

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.
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.
