What is the relationship between the shielding radius of the buy small mobile phone jammer

We should all know that in many countries, there are no clear legal regulations on buy small mobile cell phone jammer devices, but for our use, we should also understand the relevant precautions, including the protection of equipment performance, and where I can use it. Signal jammers among our common mobile phone jammers, the use of mobile phones is prohibited to prevent nuisance calls and mobile phone ringing is prohibited, while GPS satellite positioning jammers protect the whereabouts of vehicles, avoid tracking, and protect location privacy.

The interference radius of buy small mobile phone jammers in online sales may be related to the specific location you use, and sometimes it cannot reach the required range, which may be affected by the surrounding environment. You should use a signal jammer that is easy to carry and concealed interference, it can protect your privacy.

Based on many years of customer feedback and our experience, here are some details that should be paid attention to when using buy small mobile phone jammers. Please read carefully.

1. Make sure that the antenna and other accessories are installed correctly;

2. To ensure sufficient Power , the hand-held indicator turns yellow or red to indicate that the Power supply has fallen, and the shielding effect is not as usual;

3. Make sure that the mobile base station is more than 200 meters away;

4. The shielding effect depends on the surrounding environment. The interference effect of mobile phones used in suburbs is better than that of cities, because the density of urban mobile base stations is higher and the distance between base stations is relatively close, which results in the transmission of signals from urban mobile base stations (where buy small mobile phone jammers need to be blocked) than The suburbs are many times stronger;

5. When using a jammer, there should be no metal objects or wall obstructions around the antenna and between the jammer and the phone to block signal transmission;

6. Strong magnetic field and strong electromagnetic wave environment will affect the use of interference effects;

7. The installation height of the buy small mobile phone jammer is as close as possible to the device you want to shield;

8. Long-term use of interference opportunities will cause high heat and affect the interference radius;

9. When the phone is in a call, the jammer is not easy to shield the signal (the signal is very strong during the call);

10. The radio wave emitted by the buy small mobile phone jammer is a kind of high-energy material. It is normal for the machine to heat up due to the accumulation of high-energy materials;

11. The signal on the mobile phone indicates that the refresh of the grid has a certain lag. You may have turned on the interference but the mobile phone still displays the signal condition, but in fact the mobile phone cannot be used, please follow the actual effect;

12. To test the function of the GPS jammer, please download the GPS signal detection software to test the shielding effect, or open the car navigation function test;

13. A wifi jammer device with WIFI interference function will also block other appliances with WIFI, such as wireless microphones, speakers, monitors, etc.

Precautions for portable jammers

1. Charging is prohibited when using at the same time. When in use, do not charge, do not use when charging;

2. When the portable jammer is used for a long time, it is prohibited to use it, not the desktop jammer.

Pay attention to all signal jammers:

Car jammer:

Do not use the jammer before starting the car, first start the car and then insert the shielding device (the instantaneous current when the car starts is particularly strong, and it is easy to burn the mobile phone jammer)
