CPI Series 1385 3.8 M C-Band Linear Tx/Rx VSAT Antenna

CPI Series 1385 3.8 m C-Band Linear Tx/Rx VSAT Antenna

The CPI Series 1385 3.8 Meter C-Band Linear Tx/Rx VSAT Antenna provides dependable satellite communications performance for commercial, government, broadcast, and enterprise networks.

Its four-piece, glass-fiber-reinforced SMC reflector offers simplified transportation and field assembly. The offset-fed prime-focus design delivers strong gain, low sidelobes, and excellent cross-polarization performance across standard C-band transmit and receive frequencies.

Designed for demanding fixed satellite installations, the antenna withstands winds up to 125 mph in survival mode and operates in temperatures from -40°C to +60°C.
