Basic precautions 1.1 4g cell phone jammers installed
The best shield mounting height of not less than 1.8 meters from the ground.
Installation location from the base station <200 m, the shielding effect is inversely proportional to the distance from the base station. I.e., the closer base station, the smaller shield radius.
Screwed tight before the first power antenna, antenna aperture on the subject of digital antenna on the subject of digital to-one correspondence with the host, do not plug the wrong, but can not directly open the antenna is not connected host power.
1.2 4g cell phone jammers standard installation method for each component
Phone signal jammers components generally include: host, antenna, power adapter. When installing mobile phone jammers, due to the host and the antenna surrounding a certain distance (typically 20-30 cm) have a strong signal field, while the 220V power line (strong electric) peripheral (typically 5-10 cm) also has magnetic interference, so how to install how to display the location of each part will be very crucial, not positioned correctly, it may cause signal interference shielding launch, the impact of the shielding effect. Cell phone jammers installed components standard spacing, respectively:
Power adapter should be more than 20cm away from the host;
No strong power line (AC220V) within the antenna around the 20cm range;
4g cell Phone jammers compromise method of installation
If the 4g cell phone jammers during installation, the installation space restricted environments, the power adapter can not be more than 20cm lateral translation, compromise is to be placed at the bottom of the shield power adapter host, using this approach, the power adapter will still be some from the host cell phone jammers strong magnetic field interference, but with respect to the power adapter for both sides next to the host, some disruption will be less
No strong power antenna surrounding (220V / 380V)
When the 4g cell phone jammers using wall-mounted, please pay special attention, cell phone signal jammers antenna periphery (including the antenna left and right, above the antenna, the antenna embedded in the wall where strong electric dark lines, etc.) can not have a strong electric lines , where the strong electric lines are usually on the wall by means of open wire cloth or dark line is 220V or 380V AC power lines. Strong electric lines are also included to the mobile phone signal jammers itself 220V power supply cord. If the phone jammers installed after already pre-arranged location necessarily a good strong electric lines, set this pipeline bypassing modified U-shaped cell phone jammers host and antenna location. General recommended that the strong electric lines arranged in a certain distance from the bottom of the shield host.
Power adapter away from the host
4g cell phone jammer The power adapter is 220V AC to 5V DC (based jammers model, the DC voltage output of different models vary) after the mobile phone signal jammers to host powered, power adapter must be placed away from the host cell phone jammers more than 20cm position, otherwise, from the host and will lead to a strong magnetic field antenna adapter output voltage is reduced, affecting the normal operation of the host cell phone jammers, thus resulting in poor shielding effect. 4g cell phone jammer
