CPI Series 3122 1.2 M Ka-Band Linear Rx/Tx VSAT Antenna

CPI Series 3122 1.2 M Ka-Band Linear Rx/Tx VSAT Antenna

The CPI Series 3122 1.2 M Ka-Band Linear Rx/Tx VSAT Antenna provides exceptionally broad frequency coverage for commercial, government, and enterprise satellite communications.

It operates across 18.30-22.20 GHz receive and 27.00-32.00 GHz transmit frequencies. Its one-piece, Ka-band-formulated SMC reflector and offset-fed prime-focus design deliver high gain, narrow beamwidth, and excellent cross-polarization isolation.

The compact antenna supports WR42 receive and WR28 transmit interfaces with continuous fine adjustment for accurate Ka-band satellite alignment. Available now at Esatcom Inc.
