Considerations for Installing Low and High Power Cell Phone Jammers

Ensuring Effective Signal Jamming in Indoor and Outdoor Environments

Cell Phone Jammers are commonly used to block cellphone signals, both indoors and outdoors. However, the power requirements and installation considerations differ depending on the location. This article discusses the key factors to consider when installing low and high power Cell Phone Jammers, focusing on the need for rain and lightning protection.

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 rainwater from splashing into the ventilation louvers. Furthermore, ensuring the waterproofing of the power supply cable is essential. Regular inspections should be conducted to identify any potential malfunctions in the signal jammer.

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 main unit, 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, the rain cover should extend approximately 15 centimeters beyond the jammer to protect the ventilation louvers from rainwater. Additionally, the power supply cable should be waterproofed, and regular inspections should be conducted to ensure the proper functioning of the signal jammer.

Outdoor Considerations

In addition to rain protection, high power Cell Phone Jammers used outdoors may require lightning protection. This can be achieved by welding a lightning rod to the antenna bracket and inserting 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 building’s lightning protection system. Furthermore, the power supply cable’s connectors should be adequately waterproofed to prevent any damage caused by water infiltration.


Whether installing low or high power Cell Phone Jammers, it is crucial to consider the environmental conditions and take appropriate measures to ensure their effective operation. Rain protection, including the installation of rain covers and waterproofing of power supply cables, is essential for both types of jammers. Additionally, high power jammers used outdoors should also be equipped with lightning protection measures. By following these guidelines and conducting regular inspections, the reliability and performance of Cell Phone Jammers can be maintained, providing effective signal blocking solutions in various environments.
