There are two types of 4g lte gps tracking device antenna modules: built-in antenna and external antenna. Some friends do not know the difference between the two, and do not know whether different antenna modules will affect the positioning.
1. Built-in antenna: It is not easy to find after the device is installed. It is difficult for people with bad purposes to find the 4g lte gps tracking device for damage. It has good concealment and high safety factor. But because the antenna is built-in, signal takeover is not very good. If you do not pay attention to the installation, it is easy to cause the satellite to be unable to search, or the signal is not good, and the positioning is not accurate.
2. External antenna: The GPS signal of the external antenna is much stronger, and it can easily locate the vehicle in a large range. The bad thing is that the external antenna of the device lets people know at a glance that it is taking over the signal. As long as the antenna is cut off, the equipment will be damaged and the safety level is low.
When choosing the 4g lte gps tracking device antenna module, you should choose to use the 4g lte gps tracking device according to your own usage. If we manage our own car, not to prevent bad guys and thieves, of course it is better to have an external antenna. If it is a business car, a leasing company, or cargo tracking, it is best to use the built-in one, which is not easy to find.
