DatasheetFast Tune VHF/UHF Antenna
30 - 512 MHz
SKU: 21-150-200
The 21-150-200 is the latest in a series of high gain, digitally tuned VHF/UHF antennas providing outstanding performance in a physically small package of just 9.5 inches (241mm) height. This antenna has the additional benefit of having the same footprint size and fixings as AS3191. Latest p-i-n diode tuning technology for VHF band combined with a passive susceptance corrected element for the UHF band provides capability for use with both multiband VHF/UHF radios and when used with external diplexer type 21-80-25, UHF EPLRS radios working in the 420 - 450 MHz frequency range. A separate, lightweight logic converter unit (LCU) accepts data from the VHF/UHF radio, and using latest FPGA technology, provides tuning codes for the antenna. Tuning time, which is 100% radio silent, is typically 60µ second.
- Radio silent tuning within typically 60µS
- Only 9.5 inches (240mm) height
- Latest FPGA logic converter unit technology
- Can accept both VHF/UHF and EPLRS radio inputs (via diplexer)
- 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
- EMI/EMC design to MIL-STD-461
- -54° to +75°C operating (Antenna) -40° to +75° operating (LCU)
- Footprint and fixing compatible with AS3191
