Considerations for Indoor and Outdoor Installation of Low and High Power Cell Phone Jammers

Ensuring Effective Signal Blocking and Protection Against Environmental Factors

Cell Phone Jammers are commonly used to block cellphone signals in both indoor and outdoor environments. However, the choice between low and high power jammers depends on the specific requirements of the location. While low power jammers are typically used indoors, high power jammers are employed in larger and more open spaces. This article discusses the considerations for installing both low and high power Cell Phone Jammers, focusing on protection against rain and lightning.

Installation of Low Power Cell Phone Jammers:

When using low power Cell Phone Jammers outdoors, it is crucial to protect them from rain. To achieve this, a rain cover should be installed above the jammer, with the edges extending approximately 20 centimeters beyond the device. Additionally, the sides of the rain cover should also extend about 15 centimeters beyond the jammer to prevent water from splashing into the ventilation louvers of the cooling fan. Furthermore, ensuring the waterproofing of the power supply cable is essential for the proper functioning of the jammer. Regular inspections should be conducted to identify any potential malfunctions.

Installation of High Power Cell Phone Jammers:

The enclosures of high power Cell Phone Jammers are designed to be waterproof before leaving the factory. Under normal rainfall conditions, there is no need to worry about water entering the enclosure. However, it is important to consider the installation height of the jammer, ensuring it meets the requirements of the installation environment and is higher than the historical highest water level at the location. Similar to low power jammers, a rain cover should be installed with the sides extending approximately 15 centimeters beyond the jammer to prevent water from splashing into the ventilation louvers of the cooling fan. Additionally, the power supply cable should be waterproofed. Regular inspections are necessary to detect any potential faults.

Protection Against Lightning:

When using high power jammers outdoors, it is not only important to protect them from rain but also to take necessary precautions against lightning. One method is to weld a lightning rod onto the antenna bracket and insert a steel rod, approximately 2 meters long, into the ground. The other end of the steel rod should be welded to the antenna bracket or lightning rod, or connected to the lightning protection network on the rooftop.


Whether installing low or high power Cell Phone Jammers, it is crucial to consider the environmental factors and take appropriate measures to ensure their effective operation. Protection against rain and lightning is essential for maintaining the functionality and longevity of the jammers. By following the recommended installation guidelines and conducting regular inspections, users can maximize the performance of these devices and effectively block unwanted cellphone signals.
