As a senior manufacturer of signal jammer, Nanjing Baikang Electromechanical Technology Co., Ltd. has made the following summary on the way of man-made destruction of signal jammers in the process of producing and selling signal jammer in recent 20 years, the investigation of customers' actual use site and the description of customers' real-time feedback on the use status:

There are three ways to destroy the Signal Jammer artificially:

1. Artificial destruction of antenna: This is mainly aimed at the Signal Jammer of external antenna. Some people who have the idea of resisting the use of signal jammer, once they see the antenna, the first thing they think of is to screw it down and throw it away. This is a rough form of destruction, and once the antenna is thrown away, it is difficult to find it again. Without the Signal Jammer of the antenna, the shielding signal transmitted by it cannot be output normally, which will soon lead to the burnout of the power amplifier. In addition, there are some shrewd saboteurs, who handle the external antenna in a hidden way. For example, after unscrewing the antenna, first remove the antenna jacket, cut off the internal antenna core, and then install it back as it is. In this way, people will not notice that the antenna is damaged. As a result, the power cannot be output normally and the power amplifier will be burned out.

2. Destroy the Signal Jammer from the perspective of power supply: This is mainly reflected in: if there is a switch on the equipment shell, directly turn off the switch of the Signal Jammer manually. This method is quite civilized. If the signal jammer is an external power adapter configured, directly unplug the connection end of the power adapter or unplug it for a distance, resulting in virtual connection of the power supply line, so that the Signal Jammer cannot get power supply. What's more, simply cut or throw away the power cord.

3. Placing a strong magnet near the antenna of the Signal Jammer will disturb the normal working frequency of the antenna to a certain extent, but it is just a disturbance. There are many working frequency bands of a signal jammer, and a certain disturbance is not enough to make the whole Signal Jammer completely unable to work normally.

Based on the above three ways to destroy the signal jammer, in order to reduce the factors and possibility of these man-made destruction, our company began to promote several years ago: the Signal Jammer adopts fully built-in antenna, built-in switching power supply, and the power interface, host switch and network interface of the equipment all adopt concealed structure, so as to prevent man-made destruction to the greatest extent.
