What should be paid attention to in the installation and use of mobile phone signal shielding equipm

　　Standard installation method for components of mobile phone signal shielding system

　　The components of mobile phone signal shielding equipment generally include: host, antenna, power adapter. When installing the mobile phone shield, due to the strong signal magnetic field within a certain distance (usually 20-30cm) between the host and the antenna, and also the magnetic field interference around the 220 V power line (strong current) (usually 5-10 cm), how to place the installation position of each component is very important. If the position is not correct, the shielding signal may be transmitted Interference, affect the shielding effect. The standard installation spacing of mobile phone shield components is as follows:

　　The power adapter should be more than 20cm away from the host; (if the mobile phone shield can not be kept away from the host due to the limitation of the site installation environment, the power adapter can be placed under the host of the shield. After adopting this method, the power adapter will still be interfered by some strong magnetic fields from the host of the mobile phone shield, but the power adapter is close to the power adapter For both sides of the host, there will be less interference.) There is no strong current line (AC220V) within 20cm around the antenna; (including the strong current dark lines embedded in the left and right sides of the antenna, above the antenna and in the wall where the antenna is located, if it is unavoidable, please try not to be within 10cm of the antenna)

　　The installation height of the shield should be no less than 1.8m above the ground.

　　When the distance between the installation location and the base station is less than 200 meters, the shielding effect is inversely proportional to the distance from the base station. That is, the closer the base station is, the smaller the shielding radius is.

　　Tighten the antenna before power on. The antenna should be vertical (⊥). The number marked on the antenna should correspond with the number marked on the antenna hole on the host. Do not insert the antenna incorrectly, or turn on the power supply of the host without connecting the antenna.

　　Frequently asked questions about the use of mobile phone signal shield

　　1. Why is the shielding range different from that described in the manual when the shield works?

　　A: the shielding range of the shielding device is related to the electromagnetic field at the shielding site and the distance from the communication station. It is generally the best when it is 200 meters away. The manufacturer is in general test, so the shielding range will be a little different.

　　2. Can mobile phone signal shield have radiation, is it harmful to human body?

　　A: about radiation, as long as electronic products are large and small, there will be radiation. Any electrical equipment will have radiation. Just like the mobile phones we usually use, it is inevitable that there will be radiation when we lean against the ears every day. The state has also set a standard for the radiation of mobile phones. The radiation generated by the signal shielding device of mobile phones is much lower than the national standard. Moreover, it does not rely on the side of the ears every day, so there is almost no harm to the human body.
