High Gain Digitally Tuned VHF/UHF Antenna

The 21-150-67 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.

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- 150-67 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.
