Why do desktop jammers choose built-in antenna?
With the continuous development of communication technology, the mobile network has also been updated several times, from the original 2G mobile phone network to the current 3G, 4G and 5G mobile phone signal network. At the same time, the desktop jammer has also undergone continuous updates.
The desktop jammer is mainly used in school exams, college entrance exams and some venues where the use of mobile phones and other communication devices is prohibited. With the increase of communication network frequency bands, the jammer has changed from the original 4-channel antenna to the 8-channel antenna or even the 12 channel antenna, until now the built-in antenna table jammer.
The appearance of the first built-in antenna wireless jammer conforms to modern aesthetic conditions, which also eliminates the need to screw on the antenna one by one when using.
Second, the built-in jammer is more environmentally friendly and safe. After the external metal shell jammer has been turned on for a long time, the machine will generate a high temperature of 50-60 degrees, which also has this certain potential safety hazard. The built-in antenna desktop jammer has a plastic shell to solve this problem.
Third, it is easier to carry, more practical, and the repair rate is lower. Because the old external antenna desktop jammer often has antenna loss or damage before, the internal antenna has both the transmission antenna and the power supply built into the plastic housing, so it is very simple and convenient to use and carry. When necessary, you only need to connect the power supply to open the business, At the end of use, it is unnecessary to disassemble the antenna but only need to turn off the power supply, so the use efficiency is greatly improved and the maintenance cost in the later period is reduced.
