Blocking Cell Phone Number From Caller Id Installed On The Host

The high-power Blocking Cell Phone Number From Caller Id antenna emits high-power radio frequency signals. The antenna is installed outside the car body. The metal material of the car body can block the error signal and electromagnetic radiation to a large extent. Even if it is used for a long time, it will hardly affect people. It can be ignored, but if it is placed in the car, the impact will be severe. We have had clients before, experienced and tested them firsthand. As a result, after 40 minutes, he himself said that his eyes were blurry and his head was a little swollen.

It can be installed in the car and connected to the external antenna through the RF feeder.

However, in some special cases, it is also feasible to use a high-power mobile phone signal jammer to shield the entire teaching building.
