DatasheetData Link/UHF MUOS Satcom and VHF/UHF LOS Antenna
240 to 385, 30 to 512 MHz and 960 to 2000 MHz
SKU: 21-52-46
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 VHF/UHF Line of Sight (LOS), IFF, TACAN, MIDS, JTIDS and Data Link
- Wide Angle pattern coverage without Hi-Lo switching
- 200 Watts CW Power handling for Satcom
- Designed to MIL-STD-810
- SINCGARS performance comparable to AS-3191 per MIL-DTL- 85670C
