Jammer Signal

And if the police jammer chooses to be equipped with a directional antenna, it is too inconvenient. The directional antenna is relatively bulky, inconvenient to carry, and takes up a lot of space. It is necessary to carry not only the directional antenna, but also the mounting bracket for the directional antenna, which is also a problem to store. And when disassembling, you need to install the directional antenna on the antenna bracket first, and then connect the police frequency jammer host through the feeder. When the police deal with the above tasks, the preparation time is relatively long, and the operation is relatively cumbersome. Therefore, directional antennas are not suitable for police to use when dealing with outdoor tasks.

The directional antenna is suitable for use in some fixed places. It is only necessary to set up the antenna and adjust the coverage angle before installing the device and the antenna. Use the feeder connection between the antenna and the device host to tighten, and then it can be used normally. We have to go through many exams, including high school entrance exams, college entrance exams, postgraduate exams, etc., CET-4 and CET-6 exams, various qualification certificate exams, and the annual civil service exam, etc. In the exam room, the most common exam room auxiliary equipment is to prevent cheating Cell phone jammers.

The current mobile phone signal jammer has basically achieved modularization, that is, different frequency bands, using different modules, through the rapid replacement of modules, can achieve rapid repair or rapid increase in frequency bands and other advantages. Adding different frequency band modules on the basis of the original mobile phone signal jammer is still a headache for many manufacturers, because at the beginning of the design, they are all designed according to the standard mobile phone frequency band, lacking different usage scenarios, and needing to increase the interference modules of different frequency bands function.

Signal Jammer

The mobile phone signal jammer produced by topsignaljammer Technology Co., Ltd. has been fully considered in the design. Later, the requirements of different frequency bands are added. Through the superposition of the radiator, the output of the original 12 channels can be easily expanded to 24 channels. For the output, the fixed holes required for superimposing the radiator are reserved, so that even if more frequency bands of mobile phone signal jammers need to be added later, there is no need to worry about the lack of space for the radiator. And it can be extended to up to 24 interference frequency modules to achieve more frequency signal interference, or to achieve the same scene through frequency refinement to expand the ability of the shielding effect.

The police usually use some police jammers to cooperate with the task of handling some illegal assemblies, mass gatherings, temporary communication control, and arresting criminal suspects. Because some places of use are different and the strength of the wireless signal at the mission site is different, the shielding range of the police jammer will also be different. By setting up the police signal jammer and setting the parameters of the police jammer, the range of the wireless signal shielding of the police jammer can be further effectively improved. The following will introduce several methods for the police shielding device to maximize the shielding range in different places.
