Overview
CPI Satcom & Antenna Technologies Inc. (CPI SAT) 1.2m KuBand VSAT Antenna Series 1122 is ideally suited for demanding
commercial applications. The one-piece compression moldedreflector 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 isconstructed from heavy gauge pre-galvanized steel for strengthand corrosion resistance. An extended Ku-Band RxTx feed isstandard with the Series 1122 Antenna.
