[0002] The working principle of the satellite antenna is to use the satellite antenna to receive weak satellite signals and reflect the satellite signals to the low-noise frequency reduction amplifier in the dish antenna. The low-noise frequency reduction amplifier amplifies this concentrated signal to hundreds of thousands of times, and then uses the oscillation circuit to convert the high-frequency satellite signal to an intermediate frequency. This intermediate frequency signal is a modulated signal, which is then demodulated and restored to an audio and video signal by a set-top box and can be input into the TV for use.

The utility model allows the rotating support column to rotate freely in its inner wall through an arc groove. The rotating support column serves as a supporting device for the adjusting plate, and the position of the adjusting plate can be rotated and adjusted. The utility model allows the movable plate to adjust its azimuth under the adjustment of the second adjusting screw through the rotation of the second adjusting nut and the third adjusting nut by the second adjusting screw.

The reducer 9 provides a larger torque output and reduction ratio, converting the high-speed and low-torque output of the stepper motor 8 into the low-speed and high-torque output of the connecting shaft 10, and then synchronously drives the connecting shaft 10 to rotate. The bevel gear 11 on the connecting shaft 10 is meshed with the bevel gear 2 12 on the column 2, and the rotational motion is transmitted to the column 2 through meshing. With the rotation of the column 2, the connecting seat 4 and the movable bracket 5 and the antenna body 6 also rotate together.
