CPI Series 3244 2.4 M Ka-Band Circular Tx/Rx Antenna, 19.40-21.20 GHz Rx / 29.20-31.00 GHz Tx

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

The CPI Series 3244 2.4 M Ka-Band Circular Tx/Rx Antenna delivers high-gain performance for commercial, government, and enterprise Ka-band satellite communications.

It covers 19.40-21.20 GHz receive and 29.20-31.00 GHz transmit frequencies. Its four-piece, Ka-band-formulated SMC reflector combines accurate RF performance with simplified transportation and field assembly.

The offset-fed prime-focus design provides narrow beamwidth, controlled sidelobes, and circular polarization performance for demanding fixed earth station applications. Available now at Esatcom Inc.
