Small power mobile phone signal jammer is commonly used for indoor mobile phone signal interference under normal circumstances. While high-power mobile phone jammers are mostly used outdoors, only a small portion are used indoors, mainly to solve the problem of using high-power mobile phone jammers indoors in relatively large and transparent indoor environments.

When using a low-power mobile phone signal jammer outdoors, the most important thing is to pay attention to rain protection. After installing the signal jammer, it is necessary to install a canopy above the mobile phone jammer. Generally, the edge of the canopy should extend about 20 centimeters beyond the mobile phone signal jammer. When installing the canopy, it is necessary to extend both sides of the canopy, and also extend about 15 centimeters beyond the jammer, in order to effectively prevent rainwater from splashing into the ventilation louvers of the cooling fan. Also note that the power supply line of the signal interference instrument can be used normally by making it waterproof. 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. Under normal rainfall, there is no need to worry about rainwater splashing into the chassis. Just pay attention to the installation height of the mobile phone signal jammer host, to meet the requirements of the on-site installation environment and also be higher than the historical highest water level at the location. When high-power interference meters are used outdoors, attention should be paid not only to rain protection, but also to lightning protection when necessary. The method of lightning protection is to weld the antenna bracket with a lightning rod, and then insert a steel rod with a length of about 2 meters into the ground. Use a steel wire to weld one end of the steel rod to the antenna bracket or lightning rod, or connect to the lightning protection network on the roof of the building. Of course, the connector of the power supply line of the high-power interference meter should also be waterproof.
