CPI Series 1122 1.2 M Ku-Band Rx/Tx VSAT Antenna

CPI Series 1122 1.2 m Ku-Band Rx/Tx VSAT Antenna

The CPI Series 1122 is a rugged 1.2 m Ku-band Rx/Tx VSAT antenna for demanding commercial satellite communications. Its precision-molded one-piece SMC reflector provides 41.5 dBi receive gain and 43.2 dBi transmit gain. A standard extended Ku-band feed covers 10.70–12.75 GHz receive and 13.75–14.50 GHz transmit frequencies, while the heavy-gauge pre-galvanized steel Az/El mount provides precise alignment and 125 mph wind survival.
