CPI Series 1194 1.8 M C-Band Linear Rx/Tx VSAT Antenna

CPI Series 1194 1.8 M C-Band Linear Rx/Tx VSAT Antenna

The CPI Series 1194 1.8 M C-Band Linear Rx/Tx VSAT Antenna provides dependable performance for commercial, government, broadcast, and enterprise satellite communications.

It covers 3.625-4.20 GHz receive and 5.85-6.425 GHz transmit frequencies. Its glass-fiber-reinforced SMC reflector and offset-fed prime-focus optics provide high gain, controlled sidelobes, and strong linear polarization performance.

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