FAQs about Methods for outdoor lightning protection of base stations
How should a lightning protection System (RBS) be formed?
The earthing network of an RBS should be formed by a ring loop surrounding the tower, equipment room and fence, at a minimum. The mean radius re of this ring loop should be not less than l1, as indicated in Figure 1 and this value depends on the lightning protection system (LPS) class and on the soil resistivity.
Are rooftop antennas protected from lightning strikes?
If the antenna is installed on the rooftop, e.g., antenna positions 2 of Figure 29, depending on the relative height of building and the installation of the antenna system, it may be considered to be inherently protected from direct lightning strikes or be impacted by or exposed to direct lightning strikes.
What is a lightning protection system (LPS)?
3.2.3 lightning protection system (LPS): Complete system used to reduce physical damage due to lightning flashes to a structure. NOTE – An LPS consists of both external and internal lightning protection system.
How to protect the navigation light system in the equipment room?
Figure 12 shows protection of the navigation light system in the equipment room. If the NL has internal control circuits or it is based on LED technology, then an SPD is required on the top of the tower to protect the lamp. This SPD can be integrated into the lamp box.
Is a telecommunication tower impacted by lightning?
If the antenna is installed on the top of telecommunication tower, e.g., antenna positions 1 of Figure 29, it is considered to be impacted by or exposed to direct lightning strikes. Refer to [IEC 62305-3] for detail information about the protection angles and volume protected by an air termination system.
How do you measure earthing resistance in a wireless base station?
In the earthing system for a single wireless base station, the earthing network, down-conductors and metal conductors make a test loop. By using a clamp meter, the earthing resistance of the entire loop can be measured, but not the earthing resistance of the earthing network.

Comparison of lightning protection types for Israeli communication cabinets
This paper describes the principles, realization and maintenance of an External Lightning Protection System according to the Israeli standard. Moreover, the differences between the Israeli Standard and the IEC. Under this guidance, the division of buildings and structures according to their purpose and type of lightning protection systems was carried out in three categories, which were divided into classes of explosive and fire-hazardous zones defined in the EIC, as well as on the type of protection zone. Choosing the right lightning protection approach starts with understanding the main system types, where each excels, and how they combine for whole-property protection. The protection. This Recommendation provides guidance on protecting indoor distribution systems for mobile communication in large-scale buildings from lightning and safety risks. It emphasizes compliance with standards like IEC 62305-3, IEC 62305-4, IEC 60364 series, and ITU-T K.
