GROUNDING/LIGHTNING PROTECTION
Because of the serious consequences if the work is not done properly, grounding and lightning protection
work may be performed only by specially trained electricians!
Never perform grounding and lightning protection work if you are not a specialist with the appropriate
skills!
• The antenna must be erected to according to an industrial standard such as DIN EN 60728-11 and
grounded as specified.
• The grounding requirement is inapplicable only to those antennas: More than 2m below the edge of the
roof and at the same time less than 1.5m from buildings.
• For grounding, the mast must be connected by means of a suitable ground conductor to the lightning
protection system of the building, using the shortest route. If no lightning protection system is available:
to the building‘s ground conductor.
• Connection to the lightning protection system should be made only by a qualified lightning protection
system installation engineer.
Suitable as ground conductors are:
• A single solid wire with a cross-section of at least 16 mm² copper, at least 25 mm² aluminium or at least
50 mm² steel.
Unsuitable as ground conductors are:
• The outer conductors of antenna cables
• Metallic domestic installations (such as the metal pipework of a water or heating system), since the
permanence of the electrical connection cannot be guaranteed.
• The protective ground conductor or neutral conductor of the mains power supply.
Routing of ground conductors
• Antenna cables and grounding conductors must not be routed through rooms used for storing easily
flammable substances (such as hay or straw) or in which an explosive atmosphere can develop (such
as gases, vapors).
• If the parabolic antenna is used in an integrated antenna system (e. g. a distribution system), the
grounding measures must also be designed in such a way that grounding protection is still maintained
if individual units are removed or replaced.
• Hazards may be caused not only by thunderstorms (lightning), but also by static charges and short
circuits in the connected units.
• For safety reasons therefore in general for all antenna systems an equipotential bonding conductor of
4 mm² copper should be provided.
• The cable screens of all coaxial antenna downlink cables must be connected to the mast with an
equipotential bonding conductor.
