CPI Series 1182 1.8 M C-Band Circular Rx/Tx VSAT Antenna

CPI Series 1182 1.8 M C-Band Circular Rx/Tx VSAT Antenna

The CPI Series 1182 1.8 M C-Band Circular Rx/Tx VSAT Antenna delivers reliable performance for commercial, government, broadcast, and enterprise satellite communications.

It operates across 3.625-4.200 GHz receive and 5.850-6.425 GHz transmit frequencies. Its circular-polarized feed, one-piece SMC reflector, and offset-fed prime-focus optics provide dependable C-band performance in a compact antenna system.

The rugged elevation-over-azimuth mount offers continuous 360° azimuth positioning and fine adjustment for accurate satellite alignment. Available now at Esatcom Inc.
