Nowadays, the speed of electronic technology development is getting faster and faster, and the popularity of mobile phones is high. At the same time, there are many problems of credit and information leakage. The mobile phone signal jammer also appeared as a result.
Misunderstandings in the use of signal jammers:
1. The test panel signal monitor will have different effective shielding ranges in different places of use. This is closely related to the signal field strength at the scene. Different types of mobile phones may not have the same shielding range on the same site, so the selection should be based on the actual situation.
2. Factors that affect the shielding range include but are not limited to distance, direction, obstacle-free objects relative to the base station, wall materials of the site building, installation height of the protective cover, installation specifications, etc. Other factors should also be paid attention to.
3. Each antenna has a frequency band identifier, which must correspond to the frequency band identifier on the host. Before the shield is turned on, it must be ensured that each antenna is connected reliably. Do not use the device without an antenna.
4. It is normal for the surface temperature to rise above 40 degrees after the shielding is operated for a long time.
5. The normal installation height of the mobile phone signal jammer is 1.8 meters to 2.5 meters. Install it in a position where there is no obstacle between the target shielding area and the target shielding area. If the antenna needs to be vertically upward in the wall-mounted installation; when placing the table, the antenna can be folded 90 degrees and then vertically upward.
6. During use, in order to avoid possible interference to some electronic equipment, the following common equipment should be used to keep 1~2 meters.
