Rooftop sites
Due to their exposed location, rooftop sites have a higher likelihood of being affected by lightning strikes and thus also the resulting surges associated with them.
When installing mobile communication systems on roofs and hosting structures, local conditions must be taken into consideration: Can the radio system be integrated into an existing lightning protection system or must it be protected separately?
Two initial situations for the installation of a lightning protection system
Lightning protection system present
If there is already a lightning protection system on the building, the mobile communication station will be integrated into this system.
Lightning protection system not present
When constructing a new mobile communication system, setting up an isolated lightning protection system is recommended. This ensures that the separation distances to the sensitive mobile communication technology are maintained and no lightning currents can enter the hosting structure.
Both scenarios can be comprehensively dealt with using the DEHN white paper Protection for Mobile Communication Systems (4G/LTE). We are happy to provide you with this as a registered user.
Comprehensive lightning protection system for reliable protection
For a comprehensive lightning protection system, external lightning protection (lightning protection and earthing) and internal lightning protection (equipotential bonding and surge protection) must be considered in equal measure.
Equipotential bonding reduces the potential differences caused by lightning currents.
Surge protective devices prevent damage that can occur due to high electrical voltages (e.g. caused by lightning).
