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
. This
standard describes the minimum requirements for
non-isolated lightning protection. Surge voltage protec-
tion devices should installed order limit
surge voltages.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.
• 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
