Introduction:

The 4.5m antenna has the motorized turntable which is easy to operate, and it has various frequencies ranging from C-band, Ku-band to Ka-band. Our 4.5m satellite earth station is convenient for installation, the reflector can be interchanged freely and it has high precision re-installation performance.

As the advanced satellite antenna manufacturer and satellite communication provider in China, our company provides not only various kinds of satellite communication products but also a full set of service including the engineering design, installation, adjustments, maintenance and training with advantages of its solid technology background, abundant engineering experience and advanced devices and equipments. Since the installation precision of the sub reflector has a strong effect on the electronic performance of ground antenna, we have developed sub reflector of earth station antenna and will provide them to the users, the installation of the sub reflector is simple to master, and thus to avoid decreasing the antenna performance.

We provide users with particular booklets about the installation, application and maintenance of antenna, as well as technology training program to help users to install, adjust, use and maintain the system.
