DatasheetVHF/UHF/L-Band Airborne Blade Antenna
30 to 512 MHz 960 to 1220 MHz
SKU: 21-50-114
The 21-50-114 is a low profile blade antenna providing excellent UHF and L-Band performance while also providing frequency coverage in the 30-88 and 108-174 MHz bands. Radiating element design is optimized to provide excellent gain and omni-directivity in azimuth over the full 225-512 MHz and 960-1220 bands while VHF provides moderate performance only due to the antenna’s very low height.
Construction uses a glass epoxy radome bonded into an aluminum alloy base plate which carries a TNC type and SC connector and contains internal filters to isolate signals between V/UHF and L-Band. The antenna is suitable for rotary and fixed wing aircraft operating in excess of Mach 1.
- Very low height 8.2"
- 50 dB isolation with in-built filters
- Very wide band with no tuning required
- Designed to MIL-STD-810
- Fully environmentally sealed
- Suitable for Link 16, IFF, Tacan
