Admin Posted on 2022-10-27

The built-in wifi jammer means that the antenna is made in the machine. Why should the antenna be made in the machine? Wouldn't a wifi signal jammer with an external antenna be better? In fact, this statement is not entirely correct. The built-in wifi jammer device can prevent the artificial removal of the antenna and the artificial destruction of the antenna, which can also ensure a longer service life of the wifi frequency jammer and can also avoid damage to the external antenna in an irresistible environment and waste money. Replace the antenna. At this time, someone must have asked, will the effect of the machine inside the antenna be bad? In fact, it is not, because considering that the antenna is built in the machine, the built-in antenna with a gain is used in the machine so that the effect is guaranteed, the appearance is much better, and the concealment is also enhanced. but! It is not excluded that some people do not choose antennas with thicker gain in the machine for the sake of profit, but choose ordinary small antennas with poor quality, and may also make a few fewer antennas, etc., so it is very important to choose a good brand. When users choose a product, they are more concerned about two points, the shielding effect and distance; the other is the noise when the product is working.
