Grounding SAT system

Hi,

my question actually fits very well with the thread "Installation einer SAT-Anlage"

I would like to install our SAT system on the roof of our city villa myself. The laying of the coaxial cables throughout the house is included in the contract and will be laid to the attic for me. There I would like to install a 5/8 multiswitch and wire it accordingly with the LNB.

The biggest hurdle for me is probably the topic of grounding / equipotential bonding. You probably don't want and shouldn't completely do without it.
What would you recommend? Basically, do the grounding outside, lead it on the facade and into the ground with a suitable grounding rod (I would probably leave that to a professional)? Or is it sufficient to connect the SAT system to the equipotential bonding bar in the utility room? How would you implement the equipotential bonding?

wrote in the other post:

Why do you need a professional for equipotential bonding? Just run 16mm2 to the equipotential bonding bar and done...?

In this case, the cable will probably be laid inside along the wall in corresponding (specially milled) channels, right? Laying it together with other cables contradicts the purpose of grounding. I would also have an electrician do the grounding later, but it should probably be implemented/prepared as far as possible during the construction phase.

One more picture of how it currently looks on our roof:


Thanks in advance.

I’ll give my two cents, albeit a bit late.

Those questions have already been addressed.

What would you recommend to me? Basically to do the grounding outside by leading it along the facade and with an appropriate grounding rod into the ground (I would probably leave that to a professional)? Or is it sufficient to connect the SAT system to the equipotential bonding rail in the utility room? How would you implement the equipotential bonding (PA) topic?

In the German standards committee DKE K/735, it was decided in 2014 that classical lightning rods should be banned. Even though this has not yet been incorporated into any valid edition of the standards, I would never route antenna grounding conductors with dangerous proximities inside.

In that case the cable is probably laid inside along the wall in corresponding (specifically milled) channels, right? Laying it along with other cables would contradict the purpose of grounding.

This makes it easier for lightning to jump over. In the VDE publication series #6 it says: This must be warned against.

This should also be observed for buildings with photovoltaic and solar thermal systems, which by standards only need to be protected when buildings have a lightning protection system. A direct strike will usually affect all roof structures, which can only be reliably protected by separate air termination rods. For white or black tanks, a mesh width of ring conductors with maximum 10 x 10 meters is then required.

I would also have an electrician do the grounding later; however, one should ideally implement/prepare as much as possible during the construction phase.

A good planner would have provided a separate connection lug for the antenna grounding on the foundation/ring earth while it was still easily and cost-effectively possible. All grounding electrodes must be connected to each other and the equipotential bonding (HES) in a lightning current-carrying manner, see ABB information sheet #10 (currently not accessible due to new homepage) or DEHN lightning planner chapter 5.5.6 Meshing of grounding systems. A separate earth electrode would be proof of incompetence even in stainless steel (NIRO) execution.

16 mm² copper wire withstands lightning current strengths up to 200 kA, provided suitable clamps are used. Connection components on the antenna support and the HES itself must be tested according to the test standard for the wire type used class H = 100 kA.

Does this grounding system exceptionally comply with DIN 18014:2014-03 or was it also installed contrary to standards and without measurement and photo documentation by the shell builders?
