Ensuring Optimal Performance and Protection Against Environmental Factors
High-power full-band interference devices are commonly used outdoors, with only a few instances of indoor usage, particularly in large and open spaces. These devices are primarily employed to address the need for interference in expansive indoor areas with good signal penetration. This article will discuss the necessary precautions and measures to ensure the effective and safe installation of both low-power and high-power full-band interference devices in outdoor environments.

Protecting Low-Power Interference Devices from Rain:
When using low-power interference devices outdoors, the primary concern is protecting them from rain. To achieve this, it is recommended to install a rain cover above the interference device. The rain cover should extend approximately 20 centimeters beyond the edges of the device. Additionally, during the installation of the rain cover, it is crucial to ensure that both sides extend approximately 15 centimeters beyond the interference device. This arrangement effectively prevents rainwater from splashing onto the ventilation louvers of the cooling fan. Furthermore, it is essential to waterproof the power supply cable of the full-band interference device. Regular inspections should also be conducted to identify any potential malfunctions.
Waterproof Design for High-Power Interference Devices:
The chassis of high-power full-band interference devices is designed to be waterproof before leaving the factory. Under normal rainfall conditions, there is no need to worry about water splashing into the internal components of the device. However, it is important to consider the installation height of the interference device to meet the requirements of the installation environment and exceed the historical highest water level at the location. Similar to low-power devices, the rain cover should extend approximately 15 centimeters beyond the interference device to prevent water from splashing onto the ventilation louvers of the cooling fan. Additionally, the power supply cable of the full-band interference device should be waterproofed. Regular inspections are necessary to ensure the device’s functionality and identify any potential faults.
Protection Against Lightning:
When using high-power interference devices outdoors, it is crucial to not only consider rain protection but also take necessary precautions against lightning strikes. One effective method is to weld a lightning rod onto the antenna bracket. Subsequently, a steel rod, approximately 2 meters in length, should be inserted into the ground, with one end welded to the antenna bracket or lightning rod using steel wire. Alternatively, the interference device can be connected to the lightning protection system on the rooftop.
The installation of both low-power and high-power full-band interference devices in outdoor environments requires careful consideration of various factors. Protecting against rain and ensuring waterproofing of power supply cables are essential for both types of devices. Additionally, high-power interference devices necessitate attention to installation height and protection against lightning strikes. By following these guidelines and conducting regular inspections, optimal performance and longevity of the interference devices can be achieved in outdoor settings.
