In August 2023, our company cooperated with a unit in Beijing to install a set of 7.3 meter parabolic antenna. The continuous rainstorm on the site brought great difficulties to the installation and commissioning of the antenna. Our installation staff tried their best to overcome the difficulties of on-site installation and commissioning. With the assistance of customers, we successfully completed the installation and commissioning of the parabolic antenna and put it into use within the specified date, winning praise from customers. (Due to the special nature of the unit, it is not convenient to provide an on-site schematic diagram. The following diagram is a schematic diagram of our company's internal field debugging.)
