High Gain Digitally Tuned VHF/UHF + UHF/FM Antenna

The 21-500-01 tuneable antenna provides exceptional gain in the 30 - 88 MHz SINCGARS band compared to similarly sized passive antennas, and maintains optimum performance up to 512 MHz. It also provides frequency coverage from 512 to 945 MHz on a separate connector, independent of tuning to operate in the UHF/FM public services band.

Many years of experience in designing solid-state tuned antennas has enabled our engineers to provide the ultimate in performance and reliability for a frequency agile airborne blade. Close attention to environmental, EMI and lightning protection design considerations combined with latest composites structural technology makes the 21-500-01 suitable for helicopters, subsonic and supersonic aircraft under demanding tactical conditions. The separate logic converter unit combines flash memory technology with MIL spec’d power supply in a MIL-STD-461 compliant package
