I just wanted to question that. I think your attitude is great. Unfortunately, there are always people who think that the wiring for LAN is just as easy as for WLAN.

I can confidently recommend all KNX manufacturers, such as GIRA, ABB, Busch Jäger, MDT, JUNG, Merten, Schneider, Siemens, and so on; they all offer the same and the only difference is the price or the functionality of the devices.

With empty conduits, you have to check how many cables need to go through...depending on that you choose the diameter.

My patch panel is simply hanging on the wall...I believe that you don't necessarily have to get a network cabinet just because of a patch panel and a switch.

Yes, I have 17 cables from the dish inside the house to the multiswitch. 4x per LNB and 1x DVB-T.

Preparing for KNX makes no sense, since KNX wiring and conventional wiring are fundamentally different...so either do it right from the start or later you'll only have wireless stuff or some isolated solutions from some manufacturers. But basically, you only need to do the wiring correctly and the basic functions at the beginning...and later you can expand...so you can save quite a bit of money. The prerequisite is, of course, that the later programming during expansion is done by the homeowner himself or by a friend...if the electrician has to come every time, it gets expensive...

Hi, it’s a few years old, but it’s currently a relevant topic for me. To discuss the overview, I’m asking you here and not in my own thread.

You have 4 LNBs on your dish? How many satellites, besides Astra, do you want to receive or are you receiving, and why?

If I only have one LNB for Astra, with a 4-output connection, so that I then go with 4 cables to the switch and from there with 8 cables to the individual devices, can only 4 people watch different TV channels at the same time, or could I theoretically watch 4 channels and record 4 more?

4 LNBs for 4 satellites which can then be distributed to all TVs in the house. Currently, only 3 are on; the 4th LNB is underwater.

Astra 19.2
Hotbird 13.0
Astra 2A 28.2

Why 3 or 4 satellites: mainly because of UK and US channels.



There are different LNBs with 4 outputs... Quattro or Quad.

With Quattro, you still need a multiswitch and can then distribute the finished signal to any number of TVs (as many as the multiswitch allows) 4/8/16, etc. all can watch or record different programs.

With Quad, the multiswitch is already built in but only for up to 4 participants.

There is also, for example, the Octo variant, where you can run 8 cables directly from the LNB to 8 participants and all 8 can watch or record different programs.

Mycraft, either you are of Polish or Italian descent, right? At least when I look at the Hotbird satellite, it makes no sense to me otherwise, unless you understand one of the two languages

And Astra 2A is 90% English....ok, I don’t need that either. But good to know =)
Which satellite can we receive for 90% USA channels? Or can we not receive that?

So you have 4 LNBs each with 4 outputs to your multiswitch?
And from there further distributed to the individual rooms. Does each LNB need its own cable to the room, or does the multiswitch handle that?

I also always thought that you had to align the dish to the satellite, now it seems to me that I rather have to align the LNB?

We have also laid fiber optic cables from the utility room to all important locations (video wall, office, HTPC, etc.). It costs almost nothing and should not encounter any limitations at least during my lifetime.
