According to the style selection of mobile phone signal jammer, portable shield can be divided into built-in antenna and external antenna according to the style.

The advantage of choosing a built-in antenna is that if the portable jammer is fixed in the test room, the built-in antenna is better than the external antenna. The external antenna is bare. It is easy to unscrew the antenna and cut off the oscillator inside the antenna, then the jammer signal of the portable shield cannot be transmitted normally, thus losing the function of shielding the mobile phone signal. And the built-in antenna is more beautiful than the external antenna, so it is not very abrupt in the installation examination room.

The portable jammer can be used in different ways. First, fix the mobile phone signal interferer in the test room. Usage 2, take it out for use during the exam, and collect it at the end of the exam for unified storage.

The portable jammer of the external antenna is collected uniformly after the examination, which is more cumbersome than the portable jammer of the built-in antenna because the portable shield is composed of multiple modules, so there are many antennas of the mobile phone signal interferer. When collecting, it is necessary to unscrew all the antennas before putting them into the outer package of the collection shield. When selecting the collect signal shield with built-in antenna, only the shield host and power cord need to be collected. The power cord is the national standard line, even if damaged or lost, the distribution power line is more convenient. By fixing the portable shield in the test room, you can save the tedious steps of collecting the mobile phone signal interferer at the end of the test.

So, to sum up, choosing a built-in antenna and installing it in a fixed way makes it easier and more convenient to operate and greatly reduces the unnecessary steps compared to the test site. In addition, the fixed installation method can also use the intelligent management system to achieve remote unified control management, more convenient to manage, and other more practical functions, such as fault detection, which can greatly save more time on the program of device inspection.
