Description

technical field

[0001] The invention relates to an automobile component, in particular to a positioning device for an automobile rotating antenna. Background technique

[0002] A car antenna refers to a mobile communication antenna designed to be installed on a vehicle to receive and enhance radio signals. At present, the antenna pole of the car antenna is generally installed on the roof of the vehicle through the base. Since the antenna pole is fixedly connected to the base, the antenna cannot achieve the best effect of simultaneously receiving broadcasting and wireless telephones at different inclination angles. Chinese patent 200620076806.X disclosed a car antenna rotation anti-theft device on October 17, 2007. A base is installed in the outer cover, an anti-theft gasket is arranged in the base, and two connecting rings are arranged on the base. A rotating connector is installed inside; the lower part of the antenna rod is equipped with a connecting screw, which extends ...
