CPI Series 1244 2.4 M X-Band Circular Rx/Tx Antenna

CPI Series 1244 2.4 M X-Band Circular Rx/Tx Antenna

The CPI Series 1244 2.4 M X-Band Circular Rx/Tx Antenna provides high-gain performance for government, defense, emergency-response, and specialized satellite networks.

It covers 7.25-7.75 GHz receive and 7.90-8.40 GHz transmit frequencies. Its four-piece SMC reflector delivers up to 44.4 dBi gain with a 1.0 dB axial ratio and DSCS-compliant sidelobe performance.

The segmented reflector simplifies transportation and field assembly, while the elevation-over-azimuth mount provides accurate satellite positioning. Available now at Esatcom Inc.
