In the following introduction, we will also clarify the effective coverage of the pull rod box jammer.

Although the signal has brought convenience to many people, and often the function of the signal is also very strong, the limitation of the signal is that it will form a certain interference. In order to reduce the interference caused by the signal, the use of the pull rod box jammer can effectively shield the mobile phone signal, so that the mobile phone does not need to be turned off and avoid some troublesome operations.

1. When the site area is larger than the effective shielding range, it is recommended to install a variety of pull rod box jammers. Since the power supply and antenna are specially designed for the host, they shall be debugged one-to-one before delivery, so they shall not be used interchangeably.  

2. The frequency transmitted by the trolley box jammer interferes with the frequency of the base station received by the mobile phone. The relationship between shield and base station is doomed to be a competition. In the current environment, if the transmission power of the signal shield is less than the channel power transmitted by the base station to the mobile phone, the shield cannot be shielded, only the signal can be shielded.

3. How many meters a shielding layer can shield depends not only on the transmission power of the trolley box jammer itself, but also on the distance of the base station in the service environment. Buildings and signal amplification are distributed in some buildings, and it also plays an important role. Of course, the effective coverage of the pull rod box jammer does not mean that there are any specific values, which may also be affected by some factors. When using it, we can check the shielding effect of the instrument by checking the mobile phone and whether the current environment is within a certain range.
