High Gain UHF Satcom Base Station Antenna

 The 20-30-17 is a right hand circularly polarized quick-erect antenna designed for a wide range of special operational requirements. As a free-standing tripod mounted device it provides up to +14 dBiC gain and can be “pointed” in any angle thru a solid 180° to align with the satellite. It can also be hard mounted for vehicular, shelter or fixed shipborne use.

The rugged mechanical design utilizes two “director booms” that plug-in together, one of which attaches to the swivel joint and mounting post.

CAL’s foldable 20-30-101 UHF Satcom antenna module with integral “umbrella” reflector plugs into the 9 element director boom assembly to provide a robust, high gain assembly that can be deployed in under two minutes. The antenna is supplied with carry bags, cables and deployment manual. It is available with the P/N 20-50-55 tripod as P/N 20-30-18
