CPI Series 3244 2.4 M Ka-Band Circular Tx/Rx Antenna, 20.20-21.20 GHz Rx / 30.00-31.00 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 provides high-gain performance for fixed Ka-band satellite communications systems.

This configuration covers 20.20-21.20 GHz receive and 30.00-31.00 GHz transmit frequencies. Its four-piece, Ka-band-formulated SMC reflector supports accurate RF performance while simplifying transportation and on-site assembly.

The offset-fed prime-focus design delivers narrow beamwidth, controlled sidelobes, and dependable circular polarization performance. Available now at Esatcom Inc.
