The operating principle of the prior art satellite antenna receiving satellite TV is to use the satellite antenna to collect weak satellite signals and reflect the satellite signals to the low noise noise reduction amplifier (i0w noise block) installed at the focus of the dish antenna. down converter (LNB). The LNB then amplifies this concentrated signal and reduces the frequency to an intermediate frequency of about 1 GHz before transmitting it to the indoor tuner via a cable. The tuner selects the channel to be watched in the signal, and after amplification and demodulation, it is restored into an image and audio signal, and then it can be input to a TV to play a program. The dish antenna is a highly directional receiving antenna. It needs to precisely align the center of the dish antenna to a satellite over 36,000 kilometers away. Taking a satellite dish antenna with a diameter of 180 cm as an example, if the position of the dish antenna is shifted left and right to the original position by 2 cm or the elevation angle is adjusted 3 cm up and down from the origin, the aircraft number will weaken. It even disappeared. It can be seen that the accuracy of the orientation of the dish antenna is very important. To accurately align multiple satellites in orbit, the dish antenna must be rotatable to adjust the azimuth, that is, adjust the so-called dish antenna elevation and rotation angle. Republic of China Patent Bulletin No. 465 8 12 (US patent 6,445,361 B2 is the corresponding case) discloses a fixing device of a dish antenna, which includes a dish antenna fixing base and an elevation angle adjusting base.

A concentric shaft and three concentric grooves are used to fix the dish antenna fixing base and the elevation angle adjusting base with bolts. By adjusting the mutual position between the three screw holes and the concentric groove, the rotation angle of the dish antenna can be adjusted. This conventional technology integrates the elevation adjustment seat originally divided into two pieces into one to increase the overall rigidity. Generally speaking, the strength specifications of the satellite receiving system must be able to achieve a wind pressure of 60 m / s. However, the wind direction varies with the season and climate, so in addition to having to withstand the forward wind pressure of the dish antenna, sometimes it must also provide sufficient lateral resistance. This conventional technique only uses three bolts to fix the dish antenna fixing base and the elevation angle adjusting base, and its resistance to the lateral shear force is still insufficient.
