CPI Series 1182 1.8 M Ku-Band Linear Rx/Tx VSAT Antenna

CPI Series 1182 1.8 M Ku-Band Linear Rx/Tx VSAT Antenna

The CPI Series 1182 1.8 M Ku-Band Linear Rx/Tx VSAT Antenna provides reliable high-gain performance for commercial, government, broadcast, and enterprise satellite communications.

It covers 10.70-12.75 GHz receive and 13.75-14.50 GHz transmit frequencies. Its one-piece, glass-fiber-reinforced SMC reflector and offset-fed prime-focus optics deliver narrow beamwidth, controlled sidelobes, and greater than 30 dB on-axis cross-polarization isolation.

The elevation-over-azimuth mount provides continuous 360° azimuth positioning and continuous fine elevation adjustment for accurate fixed earth station installation. Available now at Esatcom Inc.
