UPC Cable Splitter Setup: Managing Multiple Decoders & Antenna Pass-through Connections

Question

Hello I have a cable from UPC and it looks like this: 1. The cable goes to splitter # 1: One of the legs goes to the TV, the other one as below (point 2) 2. The second splitter, which splits the signal into 3 wires: - cable 1 not used (there was a Mediabox no.2 decoder) - cable 2 UPC Horizon...

It actually depends on what your contract with UPC allows you to do when it comes to messing around with the wiring in your apartment. I understand that the receiver did not work when plugged into the socket? It should work without any problems, especially if the other receiver (M1, the one on the old 'flight') was working. I mean, there is something wrong with this socket: - you connected something wrong. - damaged TRIS - just swap the outputs and you will know - damaged or some 'left' cable connecting the socket to the receiver (replace it with another one) - not very sensitive M2 decoder in relation to M1 (switch receivers) When it comes to TRISs, in the past there were such sockets / splitters in cable TVs separating the signal into TV and IP modem. It can also be used as a splitter for receivers - it has equal attenuation on both outputs, but slightly higher than the standard splitter. You can also use the one on the left - this in turn is a splitter for three with the separation of the return path on the two inputs. I would put the first Teleste DSS2 splitter into the socket, which is at the entrance to the apartment and will be unused. Unless it has to remain, then one of the Tris or some decent splitter for two. How can you pass it.

Well, if the first splitter is to be left, it's difficult.

If the M1 receiver worked on the signal from Tris and M2 did not, it means that the sensitivity is very different. It happens. Generally speaking, the fact that the receivers are of the same type may not mean much. They can differ significantly both in terms of hardware and soft. I mean, it may be that when it comes to sensitivity, apart from the name, they have little in common. Or maybe the M2 is simply damaged and has low sensitivity. Possibly, the M1 has sensational sensitivity.

Another thing is that the difference in the signal level between the output from the first splitter (BSS2), and after the compilation of the second splitter (BSS3) and the new splitter for two, it will be at least 10.5 ... 11dB with a standard cable splitter, and using the Tris (right) it is about 12dB.

That's a lot. It is enough that there is not enough for the receiver. On the other hand, one dB of difference is nothing. So, if the Tris is operational and the M2 is not working, it means that it will not work with the 'standard' cable splitter.

Does the M2 work properly if driven directly from the output of splitter on 3 (BSS3)?

A good cable splitter can be difficult for you to buy in one piece - you can look at Technetix splitters, for example Wco-Line (ED-02) - representative / shop https://emea.technetix.com/pl/10430070

But before you start looking - you have to come to terms with this M2.

EDIT :

I read all the posts again, because something was bothering me, and it turned out that the M2 previously worked from the output of the three-way divider (BSS2). Horizon, in turn, shows the signal level at the BSS3 output at the level of ~ 60dBuV, so the optimum.

However, check this M2 for pickup now after BSS3, because something strange is happening - the 5dB Tris attenuation shouldn't erase it that much, especially since the M1 worked in these conditions.

Also check if the Diagnostics tab in the Mediabox menu shows the level and quality of the received signal.

Well ... I guess they just show it like that - it is or is not there. It does not necessarily have to be suitable, because sometimes sellers who do not know more about what and for what they are selling, simplify the descriptions, sometimes throwing away important information. So, you can buy it if you know the product (as long as there is no counterfeit being offered), and if you don't know it, it is better to look for an offer with a full description. It should do. But note - its declared attenuation is 4dB, and Tris has a declared 4.6dB - really - 0.6dB is no difference. It looks more and more like some kind of ailment of M2. Generally you can, but it is at least several dozen zlotys. Some kind of subscriber amplifier with a gain of 10dB. But it would be better and more convenient for UPC to raise the signal level by these few dB, if they have a spare. Even for some money for the service.

TRIS 307P is a multimedia socket from TRATEC - with 2xDATA + 1x RTV outputs. TRIS 212E is a 1/2 splitter terminal socket also from TRATEC - with a return path lock on one of the outputs.

I suspect there is too much signal attenuation as it passes through so many signal splitters and you have pixelosis as a result.

seblas · Answer

There was pixelosis once, but they increased the signal strength for me (so they said) and it was ok on all 3 decoders. Only then was each decoder on one cable coming from the other splitter. Now I have to pull 2 decoders on one cable - hence the need to use another splitter. Added after 37 [minutes]: Only from Horizon (I entered via a browser):

All decoders worked correctly with BSS3, because each decoder was connected directly to it. I think I have already done it, but I will check again in the evening (then I have to disconnect M1). I did not find diagnostics in the Mediabox menu itself. I found some test on the last channel and (if I remember correctly) the signal strength was 100%, the quality was about 70% - these were the results on MB1 and MB2 when I connected everything on Tris (all decoders connected). Well, the pixelosis on MB2 was terrible. If I see a splitter somewhere, and the attenuation is not given (e.g. here: it means that it is not suitable? Only the frequency is given (typically 5-1000 MHz). Will it be good: Another question: is it impossible to amplify this signal? For example, where there is BSS3.

I have two that stayed when the UPC technician worked for me previously: It doesn't work because those, as you called it, tees are multimedia crossovers and it is not assembled as an ordinary tee.

I used this red Tris (4.6 and 4.0 dB), but most of all I replaced the cables, i.e. the standard antenna cables (those directly to the TV) were replaced with screw-on cables (+ adapter).
Now it is so that on both TVs (where there are MBs) there is a nice picture. Occasionally there is a brief pixelosis to survive.
I will do that for now.
I think increasing the signal strength would solve the problem.

Grzegorz740 · Answer

And this has to be confirmed by the UPC technician after taking the measurements. You will not increase the signal strength by yourself.

seblas · Answer

I used this new distributor:

There is no data on attenuation, but at the auction it was: 3.2dB.

Non-pixelated image, signal strength 100%, quality 92% (or vice versa). It's ok

To sum up: the most important thing is the correct and reliable connection of the wires and a low-loss splitter.
