DatasheetMulti-Function UHF/VHF LINK16 WNW SRW ANW2 & SATCOM Antenna
240 to 400 MHz, 30 to 2000 MHz
SKU: 21-50-71
The 21-50-71 is a rugged multifunction VHF, UHF, C/D Band and UHF Satcom antenna designed for airborne applications. A high strength aerodynamic vertical shell houses a 30 - 2000 MHz three dimensional linear element that can be used for VHF, UHF, C/D-Band line of sight “LOS” communications or UHF Satcom at low angles of elevation.
This vertical shell also supports a “Bat-Wing” shape horizontal element containing a pair of cross dipoles, connected to provide high angle, right hand circularly polarized UHF Satcom coverage.
- Hi and Lo angle UHF Satcom coverage
- Full 30 - 2000 MHz LOS communications
- Wide Band Link16/WNW/SRW/ANW2
- PRC-117G, AN/ARC-210 & AN/ARC-231 compatible
- Low wingspan minimizes loading on aircraft structure
- Designed to MIL-STD-810 Environmental Requirements
