CPI Series 1194 1.8 M X-Band Circular Rx/Tx Antenna

CPI Series 1194 1.8 M X-Band Circular Rx/Tx Antenna

The CPI Series 1194 1.8 M X-Band Circular Rx/Tx Antenna delivers reliable satellite communications for government, defense, emergency-response, and specialized X-band networks.

It operates across 7.25-7.75 GHz receive and 7.90-8.40 GHz transmit frequencies. Its one-piece SMC reflector provides up to 41.6 dBi gain, a 1.0 dB axial ratio, and DSCS-compliant sidelobe performance.

The rugged elevation-over-azimuth mount supports continuous 360° azimuth positioning and fine elevation adjustment. Available now at Esatcom Inc.
