This tuneable antenna provides exceptional gain in the 30-88 MHz SINCGARS band compared to similarly sized passive antennas whilst maintaining optimum performance right up to 600MHz. Many years of experience in designing solid-state tuned antennas has enabled CAL’s team 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 21-150-07 suitable for helicopters, subsonic and supersonic aircraft. The separate logic converter unit combines flash memory technology with MIL spec’d power supply in a MIL-STD-461 compliant package. LCU’s can be programmed for all modern digital transceivers.
