RDB2020-GPS technical drawing


Vehicular Antenna | GPS

The RDB2020-GPS is a ruggedized multiband vehicular antenna that significantly reduces the number of antennas on the vehicle. The antenna operates with legacy radios for SINCGARS and EPLRS. Multiple frequency inputs may be used simultaneously. This version of the antenna includes an active GPS antenna element integral to the matching base unit. This antenna is fully “oak beam” compliant and can be tied down to a 90 degree bend for storage or during transit.
