Please explain. Why do I need a converter with two outputs. Why can't it be one converter with one signal, separated by a decoder into two (or by a splitter). The same is true for the Multiroom service. Why doesn't it work like in the case of terrestrial TV - I have one antenna, a splitter and as many cables as TV sets and everything works.
The recording satellite tuner has two built-in receivers. The possibility applies here: I am recording program "A" and at the same time I am watching program "B". If they are on different transponders and in different polarizations, then 2 independent signals must be delivered to the tuner. The satellite tuner sends a lot of information to the converter in the form of 13 or 18 V voltage (V/H polarity change), 22 kHz signal (lower/higher band switching) and sometimes - with 2 converters - DiSEqC signal (switching between converters, e.g. Astra/HotBird ). For different transponders, the combination of these signals may be different. Hence the need to use a double LNB and two coaxial cables from the antenna to the tuner. If you assume that you want to record only what you watch, or the recording will only work when the TV is turned off, then one signal is enough. Analogue and digital terrestrial television operate on different principles. Here, the antenna is a passive element and the receivers do not send anything to it, therefore, even several dozen TV sets (AIZ - AZART networks) can "hang" on one cable. The exceptions are installations equipped with an antenna amplifier. Only the DC voltage supplying the amplifier is sent there.
Okay, that explains it all. I had no idea that the decoder was sending something to the converter.
Now that's a harder question: I have an antenna with a converter with one output and one cable for the decoder. I want to buy a multiroom in n'ce, so I need a second cable from the antenna - it's not a problem, I'll buy a converter with two outputs. The problem starts further, because the cable from the antenna to the decoder goes from the attic to the living room and is built into the wall. I can't physically run a second cable. Is there any way out of this situation?
Sending two SAT signals with one cable - TWINSENDER. A common mistake made when wiring houses and apartments is laying exactly as many cables as needed at a given moment. Most often, one cable runs from the satellite converter to the tuner. In a situation where there is a need to use a two-head tuner (with PVR) or to add a second tuner, a problem arises: how to transmit two independent satellite signals in one cable? The rescue is TWINSENDER R85260. The device allows the transmission of two independent satellite signals and a terrestrial TV signal via one coaxial cable. It is therefore the best solution for all those who cannot add another cable and want to replace a single-head SAT tuner with a PVR tuner or add a second tuner with independent reception of available programs.
Yes, it is, but financially expensive. This is the so-called Twinsender link . It works up to a certain length of cable, it's expensive, but sometimes it saves you from trouble.
Thanks for the replies, it cleared up a lot for me. Can it be done as I want? Currently my setup looks like the picture. The signal from the satellite and the terrestrial TV antenna is combined in the attic with a combiner into one, amplified, then it goes to the decoder in the living room and returns to the attic with the signal with the selected digital TV program (in analog form, of course). Then it is distributed around the apartment (there is a splitter in the attic). There is also a radio remote control extender in each room. Of course, on all TVs there is a program selected on the set-top box, which is a nuisance.
I want to install an additional multiroom decoder in room 3. It is possible not to run a cable directly from the converter to it, but to connect it via LAN (this will not be a problem). Then you can't record on the main set-top box, but I'll live with it. (green color option). I guess that should work?
The second option - I run an additional third cable (blue) from the converter directly through the splitter to room 3 and then I have all Multiroom functions in both decoders. I want room 3 to also have an analog signal from the master decoder, including the signal from the terrestrial antenna - will this work?
Regarding picture number 1: what kind of amplifier is used there and what (is it really?) is the satellite signal amplified?

It is not possible. The multiroom decoder is a normal satellite decoder and must have a direct connection to the converter.

The cable from the converter cannot go through the splitter, but directly to the tuner (sending voltages and signals to the converter!)
Instead of an amplifier, install a 4-output multiswitch in the attic and the problem will be over. You will also need to replace the converter with Quatro and run 4 wires from the converter to the attic. Then you have 1 cable from the attic for each receiver. At its end, you will mount TV/SAT sockets and you will be able to connect a single satellite tuner in each room. If you need a second SAT signal in any room, you will on this route either a second cable or the Twinsender mentioned above.
Regarding picture number 1: what kind of amplifier is used there and what (is it really?) is the satellite signal amplified?
From what I remember, it was mainly about amplifying the terrestrial TV signal, which was weak then (now it is strong, so the amplifier is probably unnecessary). And by the way, the SAT signal is amplified. I don't know exactly what kind of amplifier this is, because it was assembled 15 years ago, so big, in a massive iron casing.

There is an option in N'ce that you can connect decoders via LAN (even wifi, but then HD seems to work poorly). Then the slave decoder uses the recording input on the master decoder, and receives the signal over the LAN. However, you cannot record on the main decoder then. LAN must be like that anyway, even with the second option, because then control, permissions, etc. go to it. link

But now it passes and the amplifier and works. Ok, I can send it directly to room no. 3. Can I connect the same second TV / SAT combiner on the way to also have a terrestrial TV signal on the second decoder or on the TV right away?
So - one combiner, what is now, then TWINSENDER (the amplifier must be thrown away, because it is written that there can be no amplifier between the receiver and the transmitter) and to the main decoder. On the second combiner, the third cable from the converter and the signal from the TV antenna (previously divided by a splitter), and then to room no. 3.
The installation should look like this: Each TV has access to terrestrial signals. Each TV has access to a satellite converter. Each TV set has a signal from the modulator.
The converter is not supposed to be a quad, but a quatro. The difference is that the quad is used to connect 4 receivers, and the quatro is specially designed to work with mutiswitches. There are no quatro LNBs with a terrestrial combiner, and moreover, you have to add the signal from the modulator to the terrestrial one in the attic, so the combiner is necessary in the attic, before entering the multiswitch.
Well, that has changed a bit. I dug around a bit in the flue, because something didn't seem right to me, and I found a second cable to the converter. A long time ago I had an analog tuner for two satellites and forgot about it. So one problem is gone. The satellite signal is also not amplified, as I thought, only the signal from the modulator + terrestrial TV is amplified.
In that case, do these two cables to the main decoder have to go through the multiswitch (I want to have both the signal directly from the LNB and terrestrial TV on TV No. 3, so I guess MS is necessary), or can they go directly, and the third one to room 3 through the multiswich . To sum up, if the converter is adapted to the multiswitch, all cables from the converter must go through the multiswitch? The problem is that the cables from the antenna enter through the chimney, bypassing the attic, and only the signal from the modulator returns to the attic, unlike what I thought.
The second question: can I connect the current splitter behind the multiswitch on one output? The point is that the installation is done in every room, even where there is no TV and 9 cables come out of the splitter, and I only found a multiswitch with 8 outputs (and I don't want to lose the possibility of connecting a TV in another room). link This is MS without power (they write that it takes a signal from the SAT tuner), will it also work with a regular TV?
Dude, I've written so many times: there are no splitters for satellite signals! The entire signal goes through a multiswitch, then each output can receive each terrestrial and satellite program independently. Any other combination will degrade or prevent this property. Each output from the mutiswitch goes straight to the SAT/TV socket and there is nothing on the way except the cable. Avoid this multiswitch from the link you provided, unless you want to have constant problems. Friend mihal2002 He gave you the equipment that should be installed at your place and stick to it. TRIAX is the cheapest acceptable piece of equipment that works reasonably well. I mainly use MSR and MSV series multiswitches from TERRA. They are very good in terms of reliability.
But I want to connect only TVs using an analog TV via a splitter, i.e. the output from the modulator + terrestrial TV (TVs No. 2, possibly No. 1). Yes, I have it now and it works fine, also digital terrestrial tv. Of course, I will lead the cable to TV No. 3 directly from the converter through the multiswitch to the decoder. On TV No. 3 I can even resign from terrestrial TV, then MS is probably unnecessary if I do not want a digital signal on TV No. 2. I would like to get rid of this amplifier, but if it had to be, I understand that after summing up the signals from the modulator and terrestrial antenna can you possibly connect this amplifier before entering the MS? I will probably buy this given MS, but I want to understand what can work with what to know for the future, hence the questions.
The multiswitch indicated by mihal2002 has the so-called active terrestrial, which solves the problem of amplifiers. A signal with the same level as that coming from the terrestrial antenna will appear on every output and will reach every TV set. No matter if you use satellite or only terrestrial, no other additional devices are needed. The multiswitch does it all.
Without an amplifier it's currently snowing and the digital terrestrial is cutting, but I'm buying this multiswitch today and we'll see.,
Added after 42 [minutes]:
One more question - can I connect an ordinary socket with two TV and radio inputs to the multiswitch output (where I do not want to receive a digital signal), or does it have to be a socket separating the SAT signal from the TV?
The discussion revolves around the necessity of using two cables from a satellite antenna to a set-top box for recording purposes. A recording satellite tuner requires two independent signals to function effectively, allowing simultaneous recording and viewing of different programs, especially when they are on different transponders or polarizations. The responses highlight that while terrestrial TV can operate with a single cable and splitter, satellite systems require a more complex setup due to the need for specific voltage and signal combinations sent from the tuner to the converter. Solutions for users unable to run a second cable include using a multiband converter or devices like the Twinsender, which can transmit two satellite signals over one cable. The conversation also touches on the importance of using a multiswitch and the distinction between quad and quatro converters for proper signal distribution. Summary generated by the language model.
A long time ago I had an analog tuner for two satellites and forgot about it. So one problem is gone. The satellite signal is also not amplified, as I thought, only the signal from the modulator + terrestrial TV is amplified.
