Problems solved by technology

[0002] At present, the antenna rod and the base of the car antenna are fixed and connected by screws. Since the antenna rod is set outside the car body, it is easy to disassemble and be stolen.
Due to the fixed connection of the antenna mast to the base, it is not possible to position the antenna at different tilt angles
The antenna is not optimal for two-way transmission with simultaneous reception antennas for radio broadcasting and wireless telephony
In addition, the fixed antenna cannot adjust the antenna mast to the parallel position with the car body when the car is cleaned or transported, so it is not convenient for the cleaning and transportation of the car automatic washing machine

Description

technical field [0001] The invention relates to a rotating and anti-theft device for an automobile antenna, which relates to a rotating and fixed anti-theft self-locking device for an automobile overhead antenna. Background technique [0002] At present, the antenna rod and the base of the car antenna are fixedly connected by screws. Since the antenna rod is arranged on the outside of the car body, it is easy to be disassembled and stolen. Due to the fixed connection of the antenna mast to the base, it is not possible to position the antenna at different inclination angles. The antenna is not optimal for two-way transmission with both radio broadcasting and wireless telephony with a receiving antenna. In addition, the fixed antenna cannot adjust the antenna mast to the parallel position with the car body when the car is cleaned or transported, so it is not convenient for the cleaning and transport of the automatic car washing machine. Contents of the invention [0003] T...
