1. overall structure is simple and practical, and the welding volume is little, and light in weight easily guarantees antenna installation face quality, satisfies the antenna setting to the requirement of plane degree and roughness.
2. The mounting structure is beneficial to improving the quality of sealant and ensuring the overall sealing performance.
3. The mounting seat is welded on the car body section bar to be beneficial to reinforcing the car body section bar, and the epitaxial region of the mounting seat cover plate can be machined into an arc surface, so that the mounting seat cover plate is applicable to a car body with a car roof designed as the arc surface.
4. The whole installation is a split structure, and the installation seat is separated from the two main structures of the transition plate. The mount pad welds in the automobile body, crosses the cab apron and is used for installing the antenna, and the big problem of transformation volume that this kind of structure can effectively solve the antenna remodelling and lead to also can realize quick replacement simultaneously, improves maintainability.
