AR-50
AR Modular RF Model AR-50 is a portable, lightweight, RF sensing, band-switching, RF booster amplifier for multiband operation compatible with VHF/UHF/LOS/SATCOM tactical radio equipment supporting legacy, proprietary and emerging waveforms. Operation covers 30 to 512 MHz using high speed auto-switching filters for harmonic suppression and is SINCGARS and HAVEQUICK compatible. The amplifier is designed with a DC/DC converter to support a wide range of input voltages while not sacrificing output power. Built in protections guard against antenna mismatch, over-temperature and accidental input power polarity reversal. Built to last, the AR-50 is packaged in a rugged, IP67 rated, 2-piece aluminium enclosure. Optional fan kit, shock mount kit and interface coaxial cables are available.
