Description

TECHNICAL FIELD

[0001] The present application relates to the field of satellite communication, in particular to a satellite antenna elevation adjustment device. BACKGROUND

[0002] The satellite antenna is commonly known as a large pot, which is a metal parabolic surface, responsible for reflecting satellite signals into the feed and high frequency head located at the focal point. The function of the satellite antenna is to collect weak signals transmitted by the satellite and remove as much noise as possible. Most antennas are usually parabolic, and some multi-focus antennas are composed of spherical and parabolic surfaces. Satellite signals are concentrated at the focal point of the parabolic antenna after reflection.

[0003] For the related technology in the above, the satellite antenna needs to adjust the elevation angle during installation to improve the signal strength of the satellite antenna. The elevation angle of the general satellite antenna is adjusted by setting a sleeve at the back of the satellite antenna, placing a sliding rod in the sleeve, and then fixing the sliding rod in the sleeve by a fixing bolt. When adjusting, the fixing bolt needs to be rotated and the sliding rod needs to be slid, and finally the fixing bolt is fixed. The above operation is not only cumbersome but also difficult to control the sliding range of the sliding rod in the sleeve, and it takes time to adjust repeatedly, so it is not convenient to quickly locate the satellite signal.
