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

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

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

It operates across 18.70-21.20 GHz receive and 27.00-31.00 GHz transmit frequencies. Its specialized SMC reflector and offset-fed prime-focus design provide narrow beamwidth and accurate Ka-band performance.

The antenna delivers up to 52.40 dBi gain, greater than 35 dB transmit cross-polarization isolation, and 100 W RF power handling. Available now at Esatcom Inc.
