DatasheetLo Profile UHF Satcom On-The-Move Antenna
240 to 320 MHz
SKU: 20-30-62
The 20-30-62 is a rugged UHF Satcom antenna designed for use on military vehicles operating in worldwide conditions of service and specifically configured to provide satellite capture through hemispherical radiation pattern coverage. As such, it is ideally suited to Satcom on-the move applications where vehicle movement over rough terrain causes rapid changes in the angle subtended from the antenna to the satellite.
The 20-30-62 comprises a wide band Quadrifilar Helix, hybrid connected such as to provide essentially Right Hand Circular (RHC) polarization through a 180° solid angle.
The design and general configuration of the 20-30-62 ensures performance is minimally affected by different ground planes and mounting circumstances.
- Suitable for vehicular, ship borne and shelter installations
- Robust construction
- Hemispherical radiation pattern coverage
- All Weather operation
- 200 Watts CW Power handling
- Designed to MIL-STD-810 environmental requirements
- 8 hole mounting plate
