The two antenna vibrator installation slots 11 are respectively located on both sides of the groove 8. The two sides of the antenna array 5 are respectively embedded in the antenna vibrator installation slots 11 on both sides, and the tool 1 body supports the antenna array 5. The antenna vibrator installation slot 11 is provided to facilitate the rapid fixation of the antenna vibrator on the tool 1 and the installation of the antenna vibrator.

The anti-loosening groove can ensure that the gasket 7 does not fall off while quickly completing the installation of the gasket 7.

[0058] The side of the tooling 1 is provided with an antenna base flange 3 fixing slot, one end of the antenna base flange 3 is used to be inserted into the antenna base flange 3 fixing slot, and the openings of the antenna base flange 3 fixing slot and the antenna vibrator installation slot 11 are both facing upwards.

[0060] The tooling 1 is an integrally formed structural component.

[0061] The outer edges of the tool 1 are chamfered to ensure that no harm is caused to the operator when the tool 1 is used for assembly.

[0066] S4: Figure 5 and Figure 6 As shown, the assembled structure is taken out as a whole, and then rotated 90° in the vertical plane, and then the antenna base flange 3 of the four-arm oscillator antenna 2 is vertically inserted into the fixing slot of the antenna base flange 3, and one antenna arm 4 of the four-arm oscillator antenna 2 is placed in the groove 8 on the tooling 1, and the two antenna arms 4 on both sides of the four-arm oscillator antenna 2 are supported on the top surface of the tooling 1, and then the antenna element 2 502 is installed according to the method of step S3, thereby completing the installation of the two antenna elements 5 of the four-arm oscillator antenna 2.
