Our eternal pursuits are the attitude of 'regard the market, regard the custom, regard the science' as well as the theory of 'quality the basic, believe in the 1st and management the advanced' for microwave radiation shield, Broadband Ad Hoc Network-Dual Channel, remote sensing antennas. It using the world's leading system for reliable operation, a low failure rate, it suitable for customers choice. Our merchandise sell all over the domestic and abroad thanks for the regular and new customers support.
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.
