CPI Series 1185 1.8 M Ku-Band Dual-Axis Motorized Rx/Tx VSAT Antenna

CPI Series 1185 1.8 M Ku-Band Dual-Axis Motorized Rx/Tx VSAT Antenna

The CPI Series 1185 1.8 M Ku-Band VSAT Antenna combines high-gain RF performance with motorized dual-axis positioning for fixed satellite communications.

It operates across 10.95-12.75 GHz receive and 14.00-14.50 GHz transmit frequencies. Its one-piece SMC reflector and offset-fed prime-focus design provide reliable Ku-band performance in a compact 1.8 m antenna system.

The galvanized steel elevation-over-azimuth mount provides continuous azimuth movement, recirculating ballscrew actuators, and 0.10° tracking accuracy. Available now at Esatcom Inc.
