Standards governing the lightning protection an-
tenna systems
The rules for the connection antenna light-
ning protection system are contained various stand-
ards:
• IEC/EN 60728-11
According VDE 0855-1, the antenna system
does not replace the lightning protection system. This
standard describes the minimum requirements for
non-isolated lightning protection. Surge voltage protec-
tion devices should installed order limit
surge voltages. It
is accepted that partial lightning currents can occur
due direct strike and inductive coupling.
The figure below shows how antenna system can
be protected against lightning:
Equipotential busbar (energy and data technology)
Coaxial surge protective devices (variable)
Shielded building
Transmitter/receiver
Connection lug
Foundation earther
Antenna
Energy cable
Data cable
Coaxial cable
Air-termination system with separation distance (s)
Protection antenna system

Chapter The internal lightning protection system
.
• IEC/EN 62305-3
The antenna mast the roof building should
only connected with the air-termination system if
the antenna system not within the protected area
of the air-termination system
