L1 GPS operating at 1575.42 MHz and GLONASS operating at 1601.00 MHz. Molded radome provides enhanced protection against rain, ice and lighting strikes. Application for airborne, marine, ground vehicles, and manpack installation. The antenna features a state-of-the-art amplifier that uses advanced technologies to provide high GPS GLONASS signal levels with extremely low noise operation for fast satellite acquisition. The amplifier’s complex filering network rejects adjacent/out of band signals that interfere with the GPS GLONASS operating frequency. The antenna is capable of operating with voltages between +4 to 24 VDC, due to the amplifier’s advances voltage regulator.
