Which router for our new building?

ok I will tell him when we get an appointment

everything will be agreed upon in writing anyway in the end

we will also run all the Sat cables centrally into the technical room and from the roof from the Sat dish into the basement room 4 cables that are connected to the LNB (The Sat cables also in the empty conduit)

Which Sat dish can you recommend? does it actually not matter which one as long as it is a 4x Quattro LNB?
in the technical room we will then connect the 4 cables to the multiswitch and distribute them to the individual rooms (always 2 cables per outlet)

then put a cover on it

This is the mounting plate of the access point.

Which satellite dish can you recommend?

I like Selfsat, it just doesn't look like a "dish" and is significantly smaller than a performance-equivalent dish. For example, the H30D4.

Then please say or even better write: "must be installed in the empty conduit interchangeable"

That's when the penny drops: don't confuse empty conduits with protective conduits ;-)

We will try to place the satellite dish on the northeast roof near the window so that it can still be easily accessed later.

We have a roof tile with cable passage and a bracket for the satellite dish.

We have completely decided against satellite and rather invested the saved money in more LAN infrastructure. TV primarily runs as streaming – and if there are network issues, we have DVB-T as a backup.

We deliberately chose Sat because it is generally cheaper than IPTV and also less prone to interruptions

If the internet is down, at least we still have TV, and in a strong storm, vice versa :)

That's why I want to ask which SAT dish you could recommend to us?
