In order to ensure the best effect of the signal, in general, the installation of more than one meter and less than three meters has the best effect. The cell phone jammer is relatively small and can be fixed on the ceiling or wall with ordinary screws. Of course, it can also be used directly on a table or something. However, in this case, the effect is not very good. After installation, check to see if everything is connected well, and if there is any problem with accessories such as power supply. Finally, plug the power adapter into the adapter power socket of the machine, and directly connect the 220V power supply. Next is the test machine.

If it is only low power, it is generally used in a small open area, just enough to meet the size of a classroom. However, if it is required to pass through the wall, there will be no shielding effect after actually passing through the wall, so if you choose low power Try not to pass through the wall of the test signal jammer for the test.
