How to distribute and connect SAT cable and Ethernet?

...4 cables have to go from the satellite dish to the technical room, then to the multiswitch, and then 1 cable from the multiswitch to each room.
Can you also, for example, record 1 program and watch 1 at the same time in one room over 1 cable? Or would I need at least 2 cables per room for that?

Standard answer:
it depends ;-)

Here we have (star wiring) UKW/FM, DAB, DVB-T, DVB-S
so 3 cables outside from the antenna to the switch,
+4 cables from the uni-LNB.
Of course, you don't have to realize everything.
There are also combo antennas for UKW/FM + DAB.
The inputs of the Sat switch generally specify what fits.
Improvised indoor antennas for radio or DVB-T are generally only a last resort
(unless you live directly under the transmitting antenna).

You can also watch 1 program and record a 2nd program on Sat if both programs
are on the same transponder (lyngsat.com).
Alternatively, record DVB-T + watch DVB-S.

Or just two cables to the living room if you want to record and watch TV at the same time.

Wow, did you see the blonde, what shoes ;) , we have both cables with 1G and Sat, SAT is on more often

Unfortunately, I have hardly any idea.

I only need satellite for watching TV.

Radio runs over the internet.

Unfortunately, I can hardly find any help pages on the internet that explain everything.

I wanted to ask again why is unicable so bad?

What would the optimal king solution now look like in a new building for satellite reception in all rooms (the distribution in each room from the technical room is included in the standard)

Please explain as simply as possible

Because it causes more headaches than necessary.

Ok that means if I wire it like this, then 4 TVs can watch TV at the same time?

If I want to record on one TV and watch something else at the same time, I have to lay 2 cables there, e.g. living room, right?
