CPI Series 3244 2.4 M Ka-Band Linear Tx/Rx Antenna

CPI Series 3244 2.4 M Ka-Band Linear Tx/Rx Antenna

The CPI Series 3244 2.4 M Ka-Band Linear Tx/Rx Antenna provides wide-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 four-piece SMC reflector uses a specialized Ka-band formulation to provide accurate RF performance and dependable environmental durability.

The offset-fed prime-focus design delivers narrow beamwidth, excellent cross-polarization isolation, and precise antenna positioning for demanding fixed earth station applications. Available now at Esatcom Inc.
