Description

Satellite antenna angle adjustment device

This creation relates to a satellite antenna angle adjustment device, and more particularly to a device for adjusting the elevation angle of a satellite antenna receiving a signal.

According to the radio communication on the ground, it is often affected by terrain, atmosphere, earth curvature and spatial electromagnetic field strength, so that the normal communication battery is reflected, refracted and folded back, resulting in poor communication performance and quality.

Later, communication satellites came out and used to improve the lack of conventional radio communications. The Earth Station is a general hub for receiving satellite television signals, including: Dish antenna, Feedhorn, Low Noise Amplifier (LNA), and downconverter. Electronic equipment such as (Down Converter) and satellite receivers to efficiently receive battery signals transmitted by satellites in space orbit.

Since the satellite antenna needs to receive the microwave signal transmitted by the satellite, the dish antenna is a highly directional satellite receiving antenna, because its receiving characteristics need to be aligned with the satellite in the far center of the dish antenna (about 36,000 kilometers). ), the pointing orientation of the dish antenna requires a high degree of precision. The reason is that in order to improve the effective reception of satellite microwave signals by the dish antenna, a mechanism with an adjustable elevation angle azimuth is indispensable.
