What are the precautions for using signal jammers outdoors
Small power signal jammer is commonly used to shield indoor Mobile phone signal under normal conditions. And high-power signal jammers are mostly used outdoors, with only a small portion used indoors, mainly to solve the problem of using high-power mobile phone shields indoors in large and transparent indoor environments.
When using low-power shielding devices 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 shield. Generally, the edge of the canopy should be about 20 cm beyond the shield. When installing the canopy, both sides of the canopy should be about 15 cm beyond the signal jammer, so as to effectively prevent rain from splashing into the ventilation louver of the Computer fan. Also, pay attention to making the power supply line of the signal jammer waterproof so that it can be used normally. At the same time, it is necessary to regularly check whether the signal jammer is faulty.
The chassis of the high-power signal jammer has been waterproof designed before leaving the factory. Under normal rainfall, there is no need to worry about rainwater splashing into the interior of the chassis. Just pay attention to the installation height of the signal jammer host, which can 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 signal jammers are used outdoors, they should not only pay attention to rain protection, but also pay attention to lightning protection when necessary. The lightning protection method is to weld the antenna support to the Lightning rod, and then insert a 2m long steel chisel into the ground. One end of the steel chisel can be welded to the antenna support or the Lightning rod with steel wire, or connected to the lightning network on the roof. Of course, it is also necessary to waterproof the joints of the power supply line of the high-power signal jammer.
