1. Power supply voltage: 3 to 12V (DC voltage), the larger the range, the better;
2. Induction distance: about 0.2 meters;
3. PCB board size: 2.2cm*2.8cm;
4. Scope of application: mobile GSM signal mobile phone , PHS, fixed-line and telecom CDMA mobile phones are useless;
5. Applicable time: incoming call or during a call;


Use reminder:

After welding, the antenna, the coil at the L position can be wound around the water-based pen core, about seven or eight turns, and then in the voltage range of 3-12V, the higher the power supply voltage, the longer the sensing distance. Because the positions of the built-in antennas of different mobile phones are different, when the mobile phone calls or makes a call, you can approach the different positions of the mobile phone to the antenna respectively to see that the sensing distance of that position is better and more obvious. For the old mobile phones, the effect is better, and the current mobile phones reduce the radiation of the mobile phone, so the effect will be weakened, and the effect is more for entertainment.
