High Gain Digitally Tuned VHF/UHF & L-Band Antenna

The 21-190-06 tuneable antenna provides exceptional gain in the 30 - 88 MHz SINCGARS band compared to similarly sized passive antennas, and maintains optimum performance up to 520 MHz. It also provides frequency coverage from 960 to 1220 MHz and is compatible with IFF, Tacan, JTIDS and MIDS and other L-Band data link systems.

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 21-190-06 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.
