[0030] Reference Figures 1 to 3 As shown in the figure, this application discloses a 150MHz walkie-talkie antenna, including:

[0031] Antenna element 1, wherein antenna element 1 is a helical coil;

[0032] Connector 2, having a first end and a second end disposed opposite to each other, the first end of connector 2 being welded to one end of antenna vibrator 1;

[0033] The antenna cover 3 has a hollow structure and a cavity extending along the long axis of the antenna element 1 is provided inside the antenna cover 3. The antenna element 1 is disposed in the cavity. The antenna cover 3 is integrally formed with the first end of the connector 2.

[0034] Antenna cover 4, which is used to seal the end of the antenna cover 3 away from the connector 2.

[0035] Specifically, in this embodiment, the spacing between adjacent coils in the antenna vibrator 1 welded to the connector 2 is equal. The connector 2 and the coil are made using a jig (not shown in the figure) to ensure that the coil spacing is consistent and the performance is stable during the forming process.

[0036] Specifically, in this embodiment, the second end of the connector 2 is disposed outside the antenna cover 3, and the second end of the connector 2 is provided with an interface for connecting an adapter cable.

[0037] Specifically, refer to Figure 1 In this embodiment, the antenna cover 3 and the antenna cap 4 are bonded together with adhesive. The antenna cap 4 is made of ABS material, which is easy to process, has good electrical insulation properties, and high tensile and impact strength. It is bonded to the antenna cover 3 with 737 adhesive, which further enhances the waterproof effect and effectively improves the stability of the walkie-talkie antenna. The adhesive fixation method is effective and low in cost.

[0038] Specifically, in this embodiment, the antenna element 1 is made of copper-plated carbon steel. Copper-plated carbon steel has performance similar to pure copper, but its price is more advantageous.

[0039] Specifically, in this embodiment, the connector 2 is made of C3604 brass. C3604 brass is an environmentally friendly copper material with high strength, dense and uniform structure, good plasticity, and good corrosion resistance.

[0041] Specifically, in this embodiment, the operating frequency of the walkie-talkie antenna is 150MHz.

[0042] Using the above structure, refer to Figure 3 During installation, the first end of connector 2 is soldered to one end of antenna element 1. Sufficient solder wire is first wrapped around the soldering position of the first end of connector 2 and flux is added. Then, connector 2 is fixed with a fixture and heated and soldered using a high-frequency welding machine or a solder resist machine. This ensures consistent coil spacing and stable performance during molding, effectively improving the structural stability and service life of the walkie-talkie antenna. Next, in this embodiment, one end of antenna element 1 is soldered to connector 2, ensuring a secure connection between antenna element 1 and connector 2, effectively improving the stability of antenna element 1 and preventing it from shaking and falling off. (Refer to...) Figure 2 The first end of connector 2 and antenna cover 3 are integrally formed by external molding to ensure a good sealing effect between connector 2 and antenna cover 3. In this embodiment, when the walkie-talkie antenna is used in a non-standard manner, the antenna can quickly recover due to the elasticity of the coil, and the spacing and shape of the coil are not affected, which can ensure the stability of antenna performance.
