According to the different needs of the site, it is sometimes necessary to install the mobile phone jammer outdoors. It is designed to interfere with other wireless signals, including mobile phone signals, in the open outdoor environment. When installed outdoors, it is generally in some places where the interference range is relatively large. At this time, high-power mobile phone jammer will be selected. In addition, high-power mobile phone jammers will basically be equipped with a box with a certain waterproof capacity as the case shell. As long as the box is not flooded by water, there is basically no need to worry about water ingress inside the box. Of course, when the high-power digital frequency jammer is used outdoors, it is also necessary to carry out lightning protection treatment for the jammer. The lightning protection method is to weld the antenna support with lightning rod, and then insert a steel rod with a length of about 2 meters into the ground, and weld one end of the steel rod with steel wire to the antenna support or lightning rod.

In some outdoor environments that only interfere with a small range, you can use a low-power mobile phone jammer to install it in the outdoor place where interference is needed. First of all, the low-power mobile phone jammer does not need lightning protection, because the installation position is relatively low, and the most important thing is to do rain-proof. When designing the low-power mobile phone jammer, some waterproof designs have been made, but because the shell is not completely sealed, the waterproof ability is relatively weak. At this time, it is necessary to install a canopy above the low-power mobile phone jammer, and provide rain-proof louvers around the jammer. The size of the canopy is required to exceed the size of the jammer itself and extend about 15 cm at the front. However, the operation of the digital frequency jammer should be checked regularly, and attention should be paid to making the interface of the power supply line waterproof so that it can be used normally. Or directly choose to make a larger plastic shell, completely cover the jammer, leave sufficient openings at the bottom of the plastic shell, so that the heat of the jammer can be emitted.
