DB30512‐MVHF/UHF Dual‐Band Vehicle Antenna30‐88MHz, 225‐512MHz with optional L1 or L1/L2 GPSGeneralTactical dual‐band whip antenna, designed to be installed on armed forces vehicles, for connectionto a VHF radio 30‐88MHz and a UHF radio in the band 225‐512MHz.The antenna is designed as a monopole in the VHF band, with performance similar to an end‐fedVHF‐only antenna. The UHF part is an elevated high gain dipole which reduces distortion of theradiation patterns that could be caused by the environment of a vehicle.The antenna is available with single or duel feed in the VHF/UHF bands. Optional L1 or L1/L2 GPS isalso available.
