Installation of satellite dish on the roof

Of course, only the standard series is included in the price, that's why it is the standard series. Because 99% of builders install it. And a special series Busch Dynastie naturally costs extra. If the GÜ/BT is serious and there is mutual trust, then it works. And if not, then it is the wrong GÜ/BT.

Slightly off-topic, but when I already read "brand products like Berker, Gira or glw." everything tightens up for me. [emoji51]

On the topic: I would want to estimate between 500 and 700. What is considered a "relatively good satellite dish"?

Unfortunately, I don't have the names in mind.

The developer has named the manufacturers of satellite dishes, as I said I don't have them in mind. I also don't know which products are more expensive or cheaper, but when I look on the internet, I see that a mid-range satellite dish costs about 200€. From 1500€ then remains 1300€. Connection in the attic is included in the contract anyway. I think 1300€ for the rest is too expensive. That is what I actually wanted to know.

If the GÜ/BT is reputable and there is mutual trust, it works. And if not, then it is the wrong GÜ/BT.

...yes, or a naive, gullible client...depends on how you look at it.
As I said, it is advice to avoid stress in advance. You don't have to take it.

And trust in construction...well....but I’m not going to start that discussion here....

...yes, or a naive, trusting builder...you can see it however you want. As I said, it is advice to avoid stress in advance. You don’t have to accept it.

That’s exactly how it is, that’s why I’m asking you here [emoji6]. Who trusts anyone!?

Alternatively, have a look on Amazon to get a feel for what reasonable hardware costs. SAT technology has been around for quite a few years and is no longer rocket science, so you should be able to find something decent with a small investment.

Then compare the price of your Elis against that and ask it (or yourself) where the difference is going. To me, it sounds like a good portion is going into one's own pocket.
