[0027] Meanwhile, referring to the accompanying drawings Figure 6 The projection (top surface structure of base 1) of mounting seat 2 from top to bottom is parallelogram, preferably, the acute angle of this parallelogram is a, and a is 78 °. Referring to the accompanying drawings Figure 7 The angle between the top surface and the bottom surface of mounting seat 2 is b, and b is 30 °.

[0028] When installing the antenna seat, first connect the signal connection line inside the machine body with the signal interface at one end of interface seat 4, then bolt connection interface seat 4 on base 1, at this time the signal connection port of interface seat 4 will pass through through-hole 13 on base 1, then install mounting seat 2 on base 1, and then install signal unit on the first fixed platform 21 and second fixed platform 22, at this time the longer signal connection line can be inserted in the space between the bottom of signal unit and the inside of installation cavity 20. Finally, cover mounting seat 2 with top cover 3.

[0029] Preferably, the top of top cover 3 is equipped with four first mounting screw holes 31 distributed on the four corners of top cover 3 respectively. First mounting screw hole 31 is vertically provided on the top surface of top cover 3, and mounting seat 2 is equipped with screw hole matched with first mounting screw hole 31, so as to realize the fixed connection of top cover 3. By setting first mounting screw hole 31 on the four corners of top cover 3 and matching it with the screw hole on mounting seat 2, the stable installation of top cover 3 can be realized, which can be more convenient for installation while ensuring the stability of the internal structure of the antenna seat.

[0030] Preferably, the top of the mounting seat 2 is provided with four second mounting screw holes 24 distributed on the four corners of the mounting seat 2 respectively. The second mounting screw holes 24 are arranged vertically to the bottom surface of the mounting seat 2. The base 1 is provided with screw holes matched with the four second mounting screw holes 24. When the mounting seat 2 is connected with the base 1, accurate positioning and stable connection can be achieved through the second mounting screw holes 24, and the vertical arrangement of the second mounting screw holes 24 to the bottom surface of the mounting seat 2 can also facilitate installation.

[0031] Preferably, the upper top surfaces of the first and second fixing platforms 21 and 22 are arranged in parallel to the upper top surface of the mounting seat 2. The parallel arrangement of the upper top surfaces of the first and second fixing platforms 21 and 22 to the upper top surface of the mounting seat 2 can ensure that the signal unit is parallel to the upper top surface of the mounting seat 2 after installation, which is conducive to uniform signal emission and reception, improves the performance of the antenna and the communication quality, and also helps to reduce signal interference and loss caused by uneven installation.

[0032] Preferably, the base 1 is provided with a first rubber ring groove 11, and a sealing rubber ring is arranged in the first rubber ring groove 11. The sealing rubber ring in the first rubber ring groove 11 is arranged between the mounting seat 2 and the base 1.

The second rubber ring groove 12 is arranged correspondingly to the through hole 13, and the sealing rubber ring in the second rubber ring groove 12 is arranged between the interface seat 4 and the base 1. The cooperation of the second rubber ring groove 12 and the sealing rubber ring forms a sealing barrier between the interface seat 4 and the base 1, preventing external liquid or gas from entering the body through the through hole 13 after entering the antenna seat, further enhancing the sealing performance and protection ability of the equipment.

[0034] Preferably, the outer periphery of the top cover 3 is provided with a third rubber ring groove 32, and a sealing rubber ring is arranged in the third rubber ring groove 32. The sealing rubber ring in the third rubber ring groove 32 is arranged between the top cover 3 and the mounting seat 2. Thus, a good sealing effect can be formed between the mounting seat 2 and the top cover 3.

[0035] Therefore, the device can be symmetrically distributed and installed on both sides of the aircraft body, and the antenna has a certain inclination angle when installed through the installation base 2 with a specific inclination angle, which can optimize the signal receiving direction of the antenna under different flight attitudes to a certain extent and improve the signal receiving effect. The internal structure can also maintain the inclination angle of the signal unit after fixing the signal unit. The flight attitude of the aircraft, unmanned aerial vehicle and other flight bodies will be continuously adjusted during flight, such as pitch, roll and the like. The installation platform with an inclination angle, which can be symmetrically distributed and installed on both sides of the aircraft body, can further expand the signal coverage range of the antenna, reduce the signal blind area and maintain stable communication. At the same time, the antennas installed on both sides and inclined can reduce the interference of other antennas or aircraft structures, reduce signal reflection, refraction and diffraction and other phenomena, and make the received signal more stable and reliable. The first rubber ring groove 11, the second rubber ring groove 12 and the third rubber ring groove 32 on the top cover 3 can form a sealed barrier to effectively prevent foreign matter, liquid or gas from entering the inside of the antenna seat and the inside of the aircraft body, and adapt to the use requirements of the aircraft in various environments.
