Why do the signal jammers in the examination room choose to have built-in antennas?

In the past few years, the rapid development of communication technology and the products of various Internet companies have all been updated many times, from the previous original 2G network upgrade to the current 3G, 4G, and 5G data signal Internet, and at the same time, the signal jammers in the examination room are also constantly The upgrade has now been updated for many generations.

First of all, we must understand which places the test room signal jammer is mainly used for. According to the name, we can know that finding a signal shielding device can be mainly used in: examination rooms, schools, dormitories and other areas that need to shield signals, but now the main place of use is the test room. , the college entrance examination and some main venues where the use of mobile phones and other communication equipment is prohibited. According to the improvement of the frequency band of the communication network, the test room signal jammer has changed from the initial 4-way antenna to 8-way antenna and even 12 multi-channel antennas, until now the built-in antenna Examination room signal jammer.

1. The built-in antenna test room signal jammer has a beautiful appearance and conforms to contemporary aesthetic standards. The antennas must be screwed on one by one during use.

2. The built-in test room signal jammer has a higher low-carbon environmental protection safety factor. In the past, the full-band jammer with an external metal material shell will generate a high temperature of 50-60 degrees after a long boot time, which also has certain safety hazards. The built-in antenna The signal jammer in the examination room is made of plastic shell, which overcomes this situation very well.

3. It is more convenient to carry and has better applicability. The failure rate is lower. Because the old external antenna test room signal jammer often loses or breaks the antenna, the built-in antenna is because the transmitting antenna and the host power supply are built into the plastic shell. , so that the application is very simple and convenient to carry. When needed, just plug in the power supply and start up normally. After the application is completed, there is no need to disassemble the antenna and only need to switch off the switching power supply. Therefore, the utilization efficiency is greatly improved and Reduce post-maintenance costs.
