4.5m High-speed Rotatory Satellite Communication Antenna

4.5m high-speed rotatory satellite communication antenna

1) Antenna system advantages

High reliability, the entire antenna system is very stable;

High security, the antenna material, accessories, electrical components, etc. are in accordance with world-class standards. In the design of both the antenna itself or personal safety have adequate protection

Antenna has good wind resistance, anti-corrosion and other abilities.

Wide rotating range:azimuth can be 360°rotation, elevation up and down 90°rotation.Motorized polarization device, antenna can quickly and automatically to execute the command under the control system;

Reasonable structure, beautiful appearance and long service life;

The entire antenna technology adopts the top domestic technology, it greatly increases antennas mechanical accuracy and reduces antennas maintenance cycle;

High accuracy antenna panel;

C/Ku band compatible, linear pol, circular pol and linear /circular pol convertible all can be configured;

High gain, low sidelobe, high polarization discrimination.
