If the mobile phone signal jammer is installed in an outdoor environment, waterproof and lightning protection measures must be taken. Generally, it is recommended to choose a special installation box for the mobile phone signal jammer. Louver-style ventilation position (enhanced heat dissipation), the top of the box has a hole extending out of the antenna of the mobile phone shield (the hole is sealed with hot melt glue), and the bottom of the box has a power input hole and a diversion hole (to prevent water accumulation).
The main unit of the mobile phone signal jammer is installed on the top of the box, the antenna extends out of the box (if it does not extend out of the box, the shielding effect will be greatly reduced), and the power adapter should be placed in the lower middle of the box.
When the mobile phone signal jammer (together with the installation box) is installed outdoors, such as on the exterior wall of a building, lightning protection measures must be taken. Especially in thunderstorm-prone areas, you should pay more attention!
The lightning protection measure is actually to install lightning rods on the shield. If there is no ready-made lightning rod to buy, you can make your own lightning rod, as follows:
Choose 3-4 steel bars with a diameter of 5-10mm and a length of 50cm, sharpen one end into a needle shape, weld the other end together into a "Y" shape, and connect the welded end to the ground with an iron wire with a diameter of 2-3mm (The iron wire is protected by a PVC pipe.) The end of the iron wire to the ground is connected to a metal strip. The iron strip is generally about 50-100cm long and 2-5cm wide, and is driven into the ground deeply. If the iron sheet is hard to find, you can use 10mm steel bars instead.
The lightning rod is installed 30-50cm above the antenna of the mobile phone signal jammer. The lightning rod (including the grounded wire) should not be in contact with the mobile phone jammer or the installation box, and keep a proper distance.
