Common installation precautions for 5g signal jammers

 1. Basic precautions for installing 5g signal jammers

The installation height of the 5g signal jammer should be no less than 1.8 meters from the ground. When the installation location 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 distance to the base station, the smaller the shielding radius. Tighten the antenna before powering on. The number marked on the antenna should correspond to the number marked on the antenna hole on the host. Do not insert it wrongly, and do not turn on the host power directly without connecting the antenna.

2. Standard installation method for each component of the 5g signal jammer

The components of the 5g signal jammer generally include: host, antenna, power adapter. When installing a mobile phone jammer, there is a strong signal magnetic field within a certain distance around the host and the antenna (generally 20-30cm), and there is also magnetic field interference around the 220V power line (strong electricity) (generally 5-10cm). Therefore, how to place the installation positions of each component is very critical. If the placement is incorrect, it is likely to interfere with the transmission of the shielded signal and affect the shielding effect. The standard installation spacing of the components of the mobile phone jammer is: the power adapter is more than 20cm away from the host; there is no strong power line (AC2000V) within 20cm around the antenna;

3. Compromise installation method of 5G signal jammer

If you install a 5G signal jammer, the power adapter cannot move horizontally more than 20cm due to the on-site installation environment. The compromise method is to place the power adapter under the jammer host. After using this method, the power adapter will still be interfered by the strong magnetic field of some mobile phone signal jammer hosts, but compared to placing the power adapter close to both sides of the host, the interference will be smaller

4. No strong electricity around the antenna (220V/380V)

When the 5g signal jammer is wall-mounted, please pay special attention to the fact that there should be no strong wires around the 5g signal jammer antenna (including the left and right sides of the antenna, the top of the antenna, and the strong electric dark wires pre-buried in the wall where the antenna is located). The strong wires here refer to the open or dark wires usually laid on the wall, which are 220V or 380V AC wires. Strong wires also include 220V power lines that power the mobile phone signal jammer itself. If the location where the mobile phone signal jammer is installed must pass through the pre-arranged strong electric pipeline, please transform this pipeline into a U shape to bypass the mobile phone signal jammer host and antenna position. It is generally recommended to arrange the strong electric line at a certain distance below the jammer host

5. Keep the power adapter away from the host

The power adapter is 220V AC to 5V DC (depending on the jammer model, different models have different DC voltage outputs) to power the mobile phone signal jammer host. The power adapter must be placed more than 20cm away from the mobile phone signal jammer host, otherwise the strong magnetic field generated by the host and antenna will cause the adapter output voltage to drop, affecting the normal operation of the mobile phone signal jammer host and causing the shielding effect to deteriorate

6. Introduction to omnidirectional antennas and directional antennas

The antenna configured with the mobile phone signal jammer can be an omnidirectional antenna or a directional antenna. In normal use, the most commonly used direction of the omnidirectional antenna (whip antenna) is to keep the antenna vertically facing the sky (that is, the top of the antenna is facing up). According to the signal transmission characteristics of the omnidirectional antenna, the signal coverage range of the omnidirectional antenna can generally be regarded as a spherical area centered on the antenna. But in fact, the direction of the extension line at both ends of the antenna is the area with the weakest signal transmission. Therefore, if you want the omnidirectional antenna to achieve the maximum signal coverage radius, you should try to avoid pointing the antenna at the area you want to shield the most. For example, when the omnidirectional antenna is installed vertically facing the sky, the area around the antenna is the area where the shielded signal is transmitted the farthest, and the sky above the antenna and the ground below the antenna are the areas where the shielded signal is the weakest. Similarly, if you encounter a situation where the mobile phone shielding signal coverage range is too wide when using an omnidirectional antenna, you can adjust the direction of the antenna appropriately and point the antenna to the area where you want to shield the signal the most.

 In this Internet age, everyone has their own mobile phones and other communication devices, which brings a lot of convenience to everyone's life. However, in some special areas, mobile phones and other communication devices have brought a lot of troubles to people, such as: conference rooms, examination rooms, schools, dormitories and other areas, all encounter similar problems. At this time, we can use rf  signal jammer , which can effectively block and interfere with the signals of mobile phones and other communication devices, and help special areas solve such problems. So do you really understand what signal shielding instruments are? Let's take a look at the main problems of common signal shielding instruments. 1. What is a signal shielding instrument The signal shielding instrument uses a mobile phone to receive the mobile signal sent by the base station, which interferes with the mobile phone signal and the communication base station communication device. These equipme...

How many mobile phone signal jammers can be connected to the mobile phone shielding system?

 The mobile phone shielding system uses the TCP/IP protocol. The ID of the network version of the mobile phone signal jammer is its own IP address. Up to 254 IPs can be set in each network segment. Through network settings, different network segments can also be connected to each other. . Therefore, in theory, an unlimited number of IP addresses can be set. In the mobile phone shielding system, as long as the network between the network version of the mobile phone signal jammer and the controlling computer or server is connected, unified control through the mobile phone shielding system can be realized. Manage all the functions of the network version of the  cell phone signal jammer  under its jurisdiction. In a unit, there cannot be an unlimited number of network devices, so it is better to worry about the number of mobile phone signal jammers controlled by the mobile phone shielding system. Will the operation of the mobile phone shielding system affect the normal operat...

How effective is the wireless signal jammer when placed on the ground?

图片
 All customers who have purchased a wireless  signal blockers  are very concerned about the actual shielding effect of the shielding device when they perform a power-on test after receiving the product. Different customers must have differences due to the testing environment, testing methods and testing times. The cell phones used are also different, so the test results fed back will be greatly different. The placement or installation location of shielding equipment is also a key factor affecting the shielding effect. Then the question arises, if the wireless signal jammer is placed directly on the ground, how effective will it be? Usually when manufacturers of wireless signal jammers sell shielding equipment, there will be a detailed installation and use instructions in the packaging box. Let’s take the most common low-power wireless signal jammer used in indoor environments as an example. There should be special installation instructions in its instruction manual. The f...
