CPI Series 1122 1.2 M Ku-Band Receive-Only Antenna

CPI Series 1122 1.2 m Ku-Band Receive-Only Antenna

The CPI Series 1122 is a rugged 1.2 m Ku-band receive-only VSAT antenna for demanding commercial satellite applications. Its precision-molded one-piece SMC reflector delivers 41.5 dBi midband receive gain across 10.70–12.75 GHz. The heavy-gauge pre-galvanized steel Az/El mount provides continuous fine adjustment and supports future conversion to an Rx/Tx configuration.
