The Model AR-20H is a portable, lightweight, fully automatic band-switching RF booster amplifier for multi-band VHF/UHF Tactical Radio equipment employing legacy, proprietary and emerging waveforms. The AR-20H produces 20 Watts from a nominal 2 Watts CW/PEP radio input and covers the frequency band of 30-512 MHz. The unit has a DC voltage range of 18 to 36 VDC vehicle power. The unit is designed for use with the latest modern networking formats like ANW2C and SRW. It also includes Voltage Spike Suppression, Over Temperature Protection, RF sensing T/R Switching, Harmonic Filters, lightning protection, and protection against antenna mismatch. The AR-20H has a typical 4dB Noise figure and approximately 6dB gain Low Noise Amplifier in the receive path. The AR-20H was tested to meet specific portions of MIL-STD-461F, MIL-STD-464C, MIL-STD-704F MIL-STD-810G and RTCA/DO-160G. The amplifier is comprised of rugged 4-piece aluminum case.
