Product Details

Introduction:

We are the one of the best satellite antenna manufactures 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 advantage ,of its solid technology background ,abundant engineering experience and advanced devices and equipments .

The antenna is convenient for installation , the reflector can be interchanged freely and having high precision re-installation .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 earth station antenna, as well as technology training program to help users enable to install ,adjust , use and maintain the system.
