DatasheetGPS/UHF/MUOS Satcom & UHF Public Safety Band Antenna
240 to 385 & 500-941 MHz & L1 / L2
SKU: 21-53-46
Combining highly efficient “droopy dipoles” with a wide band, line-of-sight linear element, the 21-53-46 provides Hi-Lo angle UHF Satcom from a single connector plus a separate UHF public safety band element in a single airborne antenna. In addition, this antenna includes an L1/L2 stacked patch passive GPS element.
Element shaping and matching of the circularly polarized dipoles provides UHF Satcom coverage right through the UHF and MUOS band with useable radiation and gain typically from zenith down to 20 degrees or less above the horizon.
The robust design is suitable for helicopter and fixed wing aircraft operating up to 450 knots.
- Suitable for helicopter, vehicular, fixed and mobile applications
- Covers UHF Satcom and MUOS as well as Public Safety Frequencies and GPS
- All Weather operation
- Wide Elevation coverage without Hi-Lo switching
- 200 Watts CW Power handling for Satcom
- Designed to MIL-STD-810
