Radio Frequency blocker Jamming
When there is a metal component near the radio frequency device, the signal jammer generates an induced electromotive force on the metal body that is proportional to the electric field strength. Some metal brackets, wires, irons, etc. are placed in the working environment of many high-frequency devices, and there are even ventilation pipes, radiators, etc. in the near area of some RF devices. All of these may cause field induction. An induced electromotive force is formed and interference occurs.
There are many examples of field-induced induction, such as electric light lines, which generate interference electromotive force due to its antenna receiving effect, and interfere with other equipment through the circuit system. For high-power high-frequency equipment, its shell may also generate a large induced electromotive force to cause interference.
