The standard installation method of each component of the mobile phone signal shielding system The components of the mobile phone signal shielding device generally include: the host, the antenna, and the power adapter. When installing the mobile phone jammer, because there is a strong signal magnetic field within a certain distance (usually 20-30 cm) around the host and the antenna, and there is also magnetic field interference around the 220V power line (strong electricity) (usually 5-10 cm), so , How to place the installation position of each component is very important. If the placement position is incorrect, it is likely to cause interference to the emission of shielded signals and affect the shielding effect. The standard installation distance of each component of the mobile phone isolator is as follows: the power adapter should be more than 20cm away from the host; (if the mobile phone isolator is installed, due to the limitation of the installation environment of the site, the power supply cannot be kept away, and the power adapter can be placed in the Below the main body of the isolator, after this method is adopted, the power adapter will still be interfered by some strong magnetic fields from the main body of the mobile phone isolator, but the interference will be less compared to placing the power adapter on both sides of the main body .) There is no strong electric line (AC220V) within 20cm around the antenna; (including the left and right sides of the antenna, above the antenna, and the strong electric dark lines embedded in the wall where the antenna is located, etc. If it is unavoidable, please try not to be within 10cm of the antenna. )
The installation height of the shield is preferably not less than 1.8 meters above the ground. When the installation position is less than 200 meters away from the base station, the shielding effect is inversely proportional to the distance from the base station. That is, the closer the base station, the smaller the shielding radius. Tighten the antenna before powering on, the antenna should be kept vertical (⊥), the numbers marked on the antenna should correspond one-to-one with the numbers marked on the antenna hole on the host, do not insert the wrong one, and do not directly turn on the power of the host without connecting the antenna. FAQs on the use of mobile phone signal jammers 1. Why is the shielding range different from the description in the manual when the signal blocker works? Answer: The shielding range of the jammer is related to the electromagnetic strong field at the shielding site, and the distance from the communication station related. Generally, it is the best beyond 200 meters. The manufacturer tested it under normal conditions, so the shielding range will be a little different. 2. Will there be radiation when the mobile phone signal is shielded, and is it harmful to the human body? A: Regarding radiation, as long as it is electronic products, large and small, there will be radiation. Any piece of electrical equipment will emit radiation. Just like the mobile phones we usually use, it is inevitable that there will be radiation when we lean against our ears every day. The country has also set a standard for mobile phone radiation. The radiation generated by mobile phone signal jammers is much lower than the national standard, and it is not necessary to rely on it every day. next to the ear, so it is almost harmless to the human body.
