CPI 1.2 Meter Ku-Band RxO Antenna – Series 1122

The 1.2m Ku-Band VSAT Antenna Series 1122 is ideally suited for demanding commercial applications. The one-piece compression molded reflector is precision manufactured for high-efficiency Ku-Band operation.

The Az/El mount is designed for easy installation on standard 2-7/8” OD or 3.0” OD Installation Mounts, and features fine Azimuth and Elevation Adjustments. The Az/El mount is constructed from heavy gauge pre-galvanized steel for strength and corrosion resistance. The Series 1122 RxO Antenna utilizes the same reflector and Az/El mount as the 1122 RxTx antenna, for future upgrades.
