Fast Tune VHF/UHF Antenna

The 21-150-202 is the latest in a series of high gain, digitally tuned VHF/UHF antennas providing outstanding performance in a physically small package of just 9” in height. Latest p-i-n diode technology for VHF band combined with a passive susceptance corrected element for UHF provides excellent omnidirectional azimuthal radiation patterns throughout the entire frequency range.

A separate, lightweight logic converter unit (LCU) accepts data from the VHF/ UHF radio, and using the latest FPGA technology, provided tuning codes for the antenna. Tuning time is typically 60µs seconds and 100% radio silent.

Radio silent tuning within typically 60µs
Only 9 inches (228mm) height
Latest FPGA logic converter unit technology
Excellent radiation diagram throughout entire frequency band
Rugged design has no forward facing projections for ground handling and in-flight safety
Designed for helicopters and subsonic fixed wing aircraft to MIL-STD-810 environmental conditions
-54° to +55°C (operating)
-54° to +71°C (short term)
