In some special areas and stages of life, we may use equipment such as signal jammers, but do you know the composition and installation method of signal jammers? Let’s take a look with us:
The components of a data signal jammer for sale generally include: server, wireless antenna, and power adapter. When installing a signal jammer, there is a very strong signal electromagnetic field within a certain distance between the server and the antenna (usually 20-30 cm), and at the same time, there is also a strong electromagnetic field near the 220V power plug (weak current) (usually 5-10 cm). There is electromagnetic field interference, so the installation direction of each component is very important. Wrong placement may cause interference to the transmission of shielded signals and affect the shielding effect. The marked installation intervals of each component of the cell phone blocker are:
The power adapter should be 20cm away from the server; (If the signal shield is installed, due to the limitations of the local equipment environment, it is not possible to keep the power supply away. The power adapter can be placed under the shield server, using After this method, the power adapter will still be subject to some interference from the magnetic field of the shield server on the mobile phone. However, compared to placing the power adapter close to both sides of the computer, the interference will be less.) 20cm operating area near the antenna There are no weak current lines (AC220V) inside; (including weak current open lines on the upper and lower sides of the antenna, above the antenna, and embedded parts of the wall in the direction of the antenna, etc. If it cannot be avoided, please try not to be within 10cm of the antenna)
The device height of the jammer should be no less than 1.8 meters from the ground.
When the distance between the device and the communication base station is <200 meters, the shielding effect is inversely proportional to the distance from the communication base station. That is, the closer the communication base station is, the smaller the shielding radius is.
Tighten the antenna before plugging in. The antenna must be kept upright (⊥). The bottom data marked on the antenna must correspond to the bottom data marked on the antenna hole on the server. It is not necessary to plug it in backwards, and it is impossible not to disconnect the antenna. And immediately power on the chassis.
