What is the built-in cell phone signal jammer?

The built-in signal jammer for cell phone means that the antenna is built inside the machine. Why should the antenna be built inside the machine? Wouldn’t it be better to use a mobile phone signal jammer with an external antenna? In fact, this statement is not completely correct. The built-in mobile phone signal jammer can prevent artificial removal of the antenna and artificial destruction of the antenna. This can also ensure that the mobile phone signal jammer has a longer service life and can also prevent the external antenna from being damaged in irresistible environments and wasting money.

Go and replace the antenna. At this time, someone must have asked, will the effect of the machine be worse if the antenna is inside? In fact, no, because considering that the antenna is built inside the machine, the machine will use a built-in antenna with gain, so that the effect is guaranteed, the appearance is much better, and the concealment is also enhanced. but It is not ruled out that some people, for the sake of profit, do not use antennas with thicker gain in the machine, but choose ordinary small antennas with poor quality, and may also have fewer antennas, etc., so it is important to choose a good brand. Generally, Jinyuda's built-in signal jammer is used. After all, the machine uses a built-in antenna with gain.

signal jammer
