CPI Series 3180 1.8 M Ka-Band Circular Rx/Tx Antenna, 19.40-21.20 GHz Rx / 29.20-31.00 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 delivers reliable high-frequency performance for fixed Ka-band satellite communications.

This wider circular configuration covers 19.40-21.20 GHz receive and 29.20-31.00 GHz transmit frequencies. Its SMC reflector uses a specialized Ka-band formulation for accurate RF performance and environmental durability.

The offset-fed prime-focus antenna delivers up to 52.40 dBi gain with WR42 and WR28 waveguide interfaces. Available now at Esatcom Inc.
