Low-power cell phone signal jammers are commonly used for indoor mobile phone signal shielding under normal circumstances. High-power mobile phone jammers are basically used outdoors, and only a small number are used indoors. They are mainly used to solve the problem of large indoor areas and relatively transparent environments. High-power cell phone jammers are used indoors.

When low-power mobile phone signal jammers are used outdoors, the most important thing is to pay attention to rain protection. At this time, after the signal jammer is installed, a canopy should be installed above the mobile phone jammer. Generally, the edge of the canopy is required to exceed the mobile phone signal jammer by about 20 cm, and when installing the canopy, the two sides of the canopy should also exceed the jammer by about 15 cm, so as to effectively prevent rain from splashing into the ventilation shutters of the cooling fan. Also pay attention to waterproofing the power supply line of the signal jammer so that it can be used normally. At the same time, it is necessary to regularly check whether the mobile phone signal jammer is faulty.

The chassis of the high-power mobile phone signal jammer has been designed to be waterproof before leaving the factory. There is no need to worry about rain splashing into the chassis during normal rainfall. You only need to pay attention to the installation height of the mobile phone signal jammer host. It must meet the requirements of the on-site installation environment and be higher than the highest historical water level at the location. When the high-power jammer is used outdoors, it is necessary not only to pay attention to rain protection, but also to lightning protection when necessary. The lightning protection method is to weld the lightning rod to the antenna bracket, and then insert a steel chisel about 2 meters long into the ground, and weld one end of the steel chisel to the antenna bracket or lightning rod with steel wire, or connect it to the lightning protection net on the roof. Of course, the connector of the power supply line of the high-power jammer should also be waterproofed.
