CPI Series 1134 1.2 M X-Band Circular Rx/Tx Antenna

CPI Series 1134 1.2 M X-Band Circular Rx/Tx Antenna

The CPI Series 1134 1.2 M X-Band Circular Rx/Tx Antenna provides compact, high-performance satellite communications for government, defense, emergency-response, and specialized earth station applications.

It covers 7.25-7.75 GHz receive and 7.90-8.40 GHz transmit frequencies. Its one-piece SMC reflector and offset-fed prime-focus optics deliver up to 38.1 dBi gain with DSCS-compliant sidelobe performance.

The elevation-over-azimuth mount provides continuous positioning and fine adjustment for accurate X-band satellite alignment. Available now at Esatcom Inc.
