CPI Series 3180 1.8 M Ka-Band Circular Rx/Tx Antenna, 20.20-21.20 GHz Rx / 30.00-31.00 GHz Tx

CPI Series 3180 1.8 M Ka-Band Circular Rx/Tx Antenna

The CPI Series 3180 1.8 M Ka-Band Circular Rx/Tx Antenna provides high-gain performance for commercial, government, and enterprise satellite communications.

This configuration covers 20.20-21.20 GHz receive and 30.00-31.00 GHz transmit frequencies. Its Ka-band-formulated SMC reflector and offset-fed prime-focus design provide precise RF performance with narrow beamwidth.

The antenna delivers up to 52.60 dBi gain, greater than 30 dB on-axis cross-polarization isolation, and 100 W RF power handling. Available now at Esatcom Inc.
