DatasheetCombined Passive/Digitally Tuned VHF/UHF Antenna
30 - 960 MHz
SKU: 21-150-10
This tuneable antenna provides exceptional gain in the 30-174MHz SINCGARS and VHF band compared to similarly sized passive antennas whilst maintaining optimum performance right up to 512MHz in wide-band mode. In addition, a separate high UHF passive element provides frequency coverage up to 960MHz. Many years of experience in designing solidstate 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 and EMI design considerations combined with latest composites structural technology makes the 21-150-10 suitable for helicopters and subsonic 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 provided for most current generation digital transceivers.
