The antenna lower cover 5 is manufactured by using PBT-GF30, the PBT-GF30 is engineering plastic with glass fiber content of 30%, the strength is high, the water absorption rate and the thermal expansion coefficient are low, the dimensional stability is excellent, the antenna lower cover 5 is manufactured by using PBT-GF30, and the external dimension of the antenna lower cover is not changed under the action of mechanical force, heat or other external conditions; the mounting point of the antenna lower cover 5 made of plastic is flexible in design, can be flexibly adjusted according to the structure of the vehicle body, is attached to the vehicle body, is easy to assemble and convenient to detach, and is suitable for complex vehicle body environments; and the antenna lower cover 5 made of plastic material can reduce the weight of the waterproof grounding antenna, and the production cost is low.

In some alternative embodiments, the antenna lower cover 5 is made of metal or alloy.

The waterproof registration of the waterproof ground antenna satisfies the IP68 waterproof grade requirement through the waterproof performance test.

The application provides an automobile, including foretell waterproof ground connection antenna, waterproof ground connection antenna's earthing piece 6 and automobile body 15 crimping combine.

The present application is directed to functional enhancement and use elements, which are emphasized by the patent laws, such as the description and drawings, of the present application, but are not limited to the preferred embodiments of the present application, and therefore, all equivalents and modifications, equivalents, and modifications, etc. of the structures, devices, features, etc. of the present application are included in the scope of the present application.
