Description

Technical Field

[0001] The utility model relates to the technical field of satellite antenna equipment, in particular to an antenna transmission device and an antenna. Background Art

[0002] With the advancement of satellite communication technology, its application scope is becoming more and more extensive. As the main component of satellite communication, the types of ground satellite receiving equipment are also increasing. Satellite antennas, as signal receiving devices, need to be adjusted by angle adjustment during use to improve signal strength. For this reason, we often use antenna transmission structures to adjust the angle of satellite antennas.

[0003] For example, the utility model patent with publication number CN208797157U specifically discloses a satellite antenna that is easy to adjust the angle and install, including an antenna parabola, and support rods are fixedly installed at three equal parts of the surface edge of the antenna parabola. A signal receiver is fixedly installed at the other end of the support rod, and a signal transmission line is fixedly connected to the surface of the signal receiver. The device is more convenient and quick when adjusting the angle, and has good wind resistance and anti-falling performance.

[0004] In the above-mentioned patent disclosure, the satellite antenna is fixedly mounted on the bottom plate. When the signal receiving angle needs to be changed, the elevation angle of the satellite antenna needs to be determined first, and then the elevation angle is fixed, and then the satellite antenna is controlled to rotate on the bottom plate to receive the signal.

[0005] This working mode requires that the device must be stopped when the elevation angle of the satellite antenna needs to be adjusted, which affects working efficiency and is not convenient for adapting to signal reception in various situations. Therefore, it is necessary to provide an antenna transmission structure that can adjust multiple angles simultaneously to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention
