By realizing the multi-angle rotation of the antenna body 5, the signal reception effect in different directions can be tried to find the best reception. The receiving angle is increased, thereby improving the signal quality and stability. When the vehicle-mounted antenna is used, if it needs to be repaired or replaced, the operator can directly pull the pull rod 22 outward to disengage the locking block 20 from the locking slot 21, thereby releasing the fixing restriction between the first connector 2 and the second connector 3, and then the antenna body 5 can be directly removed. The installation of the antenna body 5 is also very simple. It only needs to position the second connector 3 and insert it into the first connector 2.
