Effectively shield various walkie-talkie signals, block (interfere) the communication between the walkie-talkie and the receiver, so that various types of wireless invisible headphones (including anti-shielding and anti-detection headphones) grafted on the walkie-talkie system cannot work normally (strong noise). or no sound)
Only shield the walkie-talkie signal, does not affect the normal operation of other electronic equipment
Green and environmentally friendly, the amount of electromagnetic radiation has been strictly tested by the "Environmental and Health-Related Product Safety Institute of the Chinese Center for Disease Control and Prevention" (this unit is a national-level authoritative certification agency for electromagnetic radiation detection). The measured value of the electromagnetic field strength at each sampling point is far low According to "Electromagnetic Radiation Protection Regulations" (GB8702-88), it has no effect on human body
Low power, only shields the signal of the walkie-talkie or receiver in the examination room, and does not interfere with the walkie-talkie outside the examination room Built-in switching power supply ensures the stability and accuracy of the signal
The operation is simple, the antenna is installed correctly, and it can run automatically when the power is turned on.
Technical indicators:
Effective shielding range: 20 meters (the transmitted 5W walkie-talkie is 100 meters away from the examination room)
The smaller the power of the walkie-talkie and the farther it is from the examination room, the larger the shielding range will be.
Transmission frequency range: all frequency bands
Transmit power: 3W
Ambient temperature: -20 - +55°C
Relative humidity: 35-85%
Power adapter: input AC160-240V 50/60Hz
Body size: 210mm*139mm*50mm
Net weight: 1Kg
