It is relatively large,

It is relatively large, but supports interference of many signal frequencies, and the power is what I want, it meets my needs! !

It can really block the communication signal, it brings us quiet

I am a hospital worker. By using this kind of jammer in hospitals, it is possible to prevent damage to the human body caused by the use of mobile phones and medical equipment failures. At the same time, I don't have to worry about the cell phone ringing noise that will be brought to patients at night.
