[0032] The top of the slider 21 is fixedly connected to the anti-interference antenna 20, and the anti-interference antenna 20 is sleeved with an outer snap ring 2. The outer snap ring 2 and the inner snap ring 11 are fixedly connected by a sliding rod 13;

[0033] A height adjustment component is provided on the bottom wall of the antenna platform 1 , and a spacing adjustment component for driving the multiple sliders 21 to move synchronously is provided inside the antenna platform 1 .

[0037] Optionally, in the above technical solution, the height adjustment assembly includes a screw B31 rotatably connected to the bottom wall of the antenna base 1, the bottom end of the screw B31 is rotatably connected to a connecting column 33, one end of a plurality of fixed rods 34 is hinged on the connecting column 33, and the bottom end of the fixed rod 34 is hinged on the counterweight block 35.

[0038] Optionally, in the above technical solution, a threaded block 32 is sleeved on the outer circumference of the screw B31 , and one end of a plurality of bent rods 36 are hinged on the threaded block 32 at equal intervals, and the other end of the bent rod 36 is hinged on the fixed rod 34 .

[0039] Furthermore, an antenna amplifier is provided at the top of the communication antenna 10 , and an anti-interference amplifier is provided at the top of the anti-interference antenna 20 .

The up and down movement of the threaded block 32 drives the bending rod 36 to rotate inward or outward. The outer end of the bending rod 36 drives the fixing rod 34 to retract or expand, thereby changing the height of the antenna station 1 (for example, Figure 2 The threaded block 32 moves to the lowest end, and the fixing rod 34 retracts to the minimum distance. At this time, the antenna station 1 is at the highest end);

When the anti-interference antenna 20 moves relative to the communication antenna 10, the sliding rod 13 follows its movement and extends and retracts.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
