There are two types of car GPS positioner antennas: built -in antennas and external antennas. Some friends do not know what the difference between the two, and do not know whether different antenna modules will affect the positioning. Today, the editor of Zhiren Technology will explain to you.

　　Built -in antennas: It is not easy to find after the equipment is installed. It is difficult for people with adverse purposes to find the positioner for damage, good concealment, and high safety factor. But because the antenna is built, the signal is not very good. If you don't pay attention to installation, it is easy to cause satellite search, or the signal is not good, and the positioning is not allowed.

　　External antenna: The GPS signal of the external antenna is much stronger, and vehicles can be easily located in a large range. It is not good that the external antenna of the device can let people know that it is taking over the signal at a glance. As long as the antenna is cut off, the equipment will be damaged and the safety is low.

　　When selecting the GPS positioner antenna module, you should choose the car GPS positioner according to your own usage. If we manage our car, it is not to prevent bad people and thieves, of course, it is better to external antennas. If it is an enterprise car, rental company, cargo tracking, etc., it is best to use built -in, it is not easy to find.
