Where should the satellite dish be installed?

An LNB can fail at any time. I would also install them where they are not constantly visible and where you can reach them.

I would also recommend attaching them where they are easily accessible. It’s not about dunking the LNB but about the winter. It has happened to me several times that snow accumulated in front of the LNB and disrupted the reception as a result. If ours were not attached in a way that made it easy to reach, there would have been a problem.

The installation location must be considered individually for each project because several factors have an influence: -Orientation to the desired satellite -Optics -Mounting bracket (rather difficult to implement on ETICS or with thermal bridges) -Lightning protection -Accessibility (on the roof next to a roof window, it may also be possible to reach to sweep off snow) -Cable routing into the house -Possible shading of a photovoltaic system etc.

One should also keep an eye on the development plan.

Look at that, finally a post with correct spelling including capitalization and understandable content. For whatever reason, it does work now and then. Why not always?

That monument protection considerations must be taken into account are exceptions.

Antennas installed detached from buildings in open countryside or on garages are generally less secure than conventionally directly grounded roof antennas. For installations in facade zones not requiring grounding according to IEC 60728-11, one should be aware that lightning currents can especially jump from rainwater downpipes.

The rolling sphere and protective angle methods have been empirically confirmed in numerous experiments in high-voltage laboratories. That facade areas ≥ 2 m below gutters and on gable sides below the roof edges and ≤ 1.5 m wall distance or the previously equally arbitrary "empirical values" of 3 m only below the gutter and ≤ 2 m wall distance are reliably safe even with soft roofing or wooden buildings has so far not been investigated and confirmed by a single high-voltage laboratory.

In previous standards, lightning current-capable grounding was nevertheless recommended even for antenna installations in supposedly safe zones. Certainly not without reason.

The best possible protection against direct strikes is provided by separated capture devices installed in compliance with standards by qualified lightning protection specialists. However, these are not available for free.

Well, a post with correct spelling including capitalization and understandable content. For whatever reason, it happens every now and then. Why not always?

OT. I do not know exactly what you mean, but I do think that my posts are mostly in correct spelling. Not to mention the recurring mistakes found in many forums: ss - ß used incorrectly das - dass used incorrectly idiot apostrophe idiot spaces etc.
