Jammer Signal

Police frequency jammers are generally portable and can be designed as a drag box or backpack. Under normal circumstances, police jammers are equipped with omnidirectional antennas. The advantages of police frequency jammer equipped with omnidirectional antennas are as follows: : 1. It is easy to carry. The omnidirectional antenna is basically a glass fiber reinforced plastic shell. When carrying, just put the antenna in the storage bag. It is best to use a special storage air box for the antenna, which takes up less space and does not need to worry about bumping. 2. Quick disassembly and assembly. When the police arrive at the mission site, they only need to connect the frequency band of the omnidirectional antenna to the frequency band interface of the police jammer, so as to tighten the omnidirectional antenna. It is also very convenient to disassemble. The antenna can be put into the storage bag. It is especially suitable for application scenarios when the police handle the above tasks.

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.

Jammer Frequency

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.

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.
