In some special areas and periods in our lives, we may use signal jammers, but do you know the composition and placement of signal jammers? Let's take a look at it next:

Signal jammer manufacturers: component composition and use of signal jammers
The components of the signal jammer generally include: a host, an antenna, and a power adapter. When installing a signal jammer, because there is a strong signal magnetic field within a certain interval (usually 20-30 cm) around the host and the antenna, and there is also a magnetic field disturbance around the 220V power line (strong current) (usually 5-10 cm), so , How to place the device orientation of each component is very critical. If the placement orientation is incorrect, it is very likely that the transmission of the shielded signal will be disturbed and the shielding effect will be affected.

The standard device spacing of each component of the mobile phone shielding device is as follows:

The power adapter should be more than 20cm away from the host; (If the signal jammer is installed, it is restricted by the installation environment of the site, and the power cannot be kept away. You can place the power adapter under the host of the jammer. After choosing this method, The power adapter will still be disturbed by the strong magnetic field from the main body of the mobile phone jammer, but it will be less disturbed compared to the power adapter close to the two sides of the main body.) There is no strong electric line within 20cm of the antenna. (AC220V); (Including both the left and right sides of the antenna, the top of the antenna, the strong electric dark wires embedded in the wall where the antenna is located, etc., if it cannot be prevented, please try not to be within 10cm of the antenna)

The height of the shielding device should be no less than 1.8 meters above the ground.

When the device's azimuth distance is less than 200 meters 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 turning on the power. The antenna must be vertical (⊥). The numbers marked on the antenna must correspond to the numbers marked on the antenna hole on the main unit. Don't plug it in wrongly, let alone turn on the main unit power without connecting the antenna.
