DB30512-M
The DB30512-M is a tactical dual band whip antenna, designed to be installed on armed forces vehicles, for connection to a VHF radio 30-88 MHz and a UHF radio 225-512 MHz.
The antenna is designed as a monopole in the VHF band, with performance similar to an end-fed VHF only antenna. The UHF part is an elevated high gain dipole which reduces distortion of the radiation patterns that could be caused by the environment of a vehicle.
The antenna is available with single or dual feed in the VHF/UHF bands. Optional L1 or L1/L2 GPS is also available.
