Maximize your range on GMRS and Commercial frequencies with the DistribuComm COMM45470. This high-performance mobile antenna features a center-loaded "phasing coil" design that effectively stacks two radiating elements, delivering a massive 5dBd gain (approx. 7.15 dBi).
Specifically designed for the 450 MHz to 470 MHz spectrum, this antenna is the ideal choice for GMRS (General Mobile Radio Service) users looking for "highway range" or Commercial Business Band fleets operating in flat terrain. The reliable NMO mount base ensures compatibility with the widest range of vehicle mounts on the market.
