[Solved] nc + unicable installation selection - ultrabox decoder and multiroom what equip

Remus 13056 18
Best answers

How should I build a satellite installation for an Ultrabox 4K plus two legacy WiFiBox receivers, and which LNB/multiswitch and coax cable should I choose?

The safest and simplest solution is an ordinary Unicable (EN50494) LNB, such as an Inverto model, because the Ultrabox only supports Unicable I; with a dCSS/Unicable II unit it will normally use the first 8 user bands by default [#17233858][#17234925] If you configure the frequencies manually, the order in the Ultrabox must match the order programmed in the converter or multiswitch [#17233858] The Johansson 9739 multiswitch can work with quad or quattro LNBs and gives 2 Unicable outputs plus 2 legacy outputs, but it needs its own power supply and may be more complex than necessary for this setup [#17234800][#17234925] For cabling, a black RG6 cable with a 1.13 mm copper core and dense braid was recommended, and Televes T100 Full Cu was specifically described as a very good choice [#17235113]

    Hello:
    Recently, I extended my contract at nc + by choosing new ultrabox 4k and 2 x wifibox decoders. I would like to expand my installation to make the most of the ultrabox. And here is my question. I currently have a Quad converter (I don't remember the company anymore). I would like to use all 8 heads in ultrabox (I read that there are so many), which is of course unicable. 2 x Legacy signal to wifibox. The cost is to be as small as possible (as few elements as possible) but a good company (I'd rather pay more than complain later).
    1. I found a converter that would probably be the best solution: LNB digital SCR Unicable II GT-SAT GT-S3dCSS24 (has 3 legacy outputs and one unicable II for 24 receivers). I don't place a link to the auction because it's on the website. The question is whether GT-SAT is a good company (I can't find an opinion, so I don't think so). Other converters have either unicable II up to 4 receivers (which does not give the use of all 8 heads) or too few legacy outputs.
    2. Another solution is to buy a multiswitch: Multiswitch Unicable 4/2, 9739 Johansson, which according to the description has 2 x unicable II with 16 receivers and 2 x legacy. According to the drawings of the connection on the store's website: https://satsklep.pl/pl/p/Multiswitch-Unicable-42-%2C-9739-Johansson/33288 it can be connected to the Quattro converter (via multiswitch) or Quad through some devices with the marking 4506. The question is, can I connect it directly to the Quattro converter (without multiswitch). And the second question, is it possible that I get so many signals at the output by connecting it to a regular Quad (and do I have to use these 4506 devices)?
    3. Any other suggestions? I do not give the amount, because I intend to pay as much as I need, but of course as little as possible (so it would be best to find a good company converter that meets these assumptions - apart from this one I have not found anything else).
    4. I also intend to replace the cabling, because when I was buying 10 years ago, I looked at the price and it probably is not of the highest quality. Is the cable: RG6U BC TriShield- Black antenna cable a good choice or is it worth investing in something else?
    I have a 100cm skull and I do not plan to replace it yet.
    Thank you in advance for your help

    The question is, what are these 8 heads for? I'm afraid nobody tested this decoder with the unicable II converter, so you will probably be the first. Good luck.

    4 heads are used to record and display tv, and the remaining 4 to speed up channel switching (so I read somewhere), so I want to have it connected in this way to make the most of the device. As no one has tested on this unicable decor, how is the connection recommended?

    The instructions are about recording 3 channels and watching 1. If you buy one of the decoder lists. Since they are on the list, I think the manufacturer tested them (hopefully).
    "UNICABLE installation allows
    watching one program at a time
    and recording at the same time
    even three different television programs,
    provides greater efficiency
    download VOD content and speed up
    channel switching. "
    Here you have a multiswitch connection link Only it is 9733 and additional decoders will not be connected.

    As for the cost, it should be the smallest in the sense that it is better to buy a converter than a quattro + multiswitch converter, because it will come out more expensive. Do you want to tell me that nobody ran it on 8 heads using unicable? Maybe it is better to use Wideband?

    The Ultrabox decoder only supports the Unicable I standard (EN50494).
    For a typical dCSS Unicable II converter, it defaults to the first 8 UB (frequency) by default. I am thinking of using ready-made converter profiles and multiswitches in the single-cable configuration menu.
    It is for the future if someone would like to install several decoders with Unicable support on one installation with a dCSS converter or a dCSS multiswitch.
    In the advanced single-cable configuration you can enter less frequency for Ultrabox and then the remaining ub can be used e.g. for multiroom decoders.
    When entering frequencies manually, make sure that the order of the frequencies used in the Ultrabox coincide with the order of the frequencies programmed in the dCSS converter or multiswitch.
    Generally, Ultrabox + has been poorly designed in this respect.

    Ok, I know a little more. I will buy a multiswitch: https://satsklep.pl/pl/p/Multiswitch-Unicable-42-%2C-9739-Johansson/33288 (2 SCR outputs and 2 legacy). According to the website: http://satkurier.pl/news/169236/instalacje-i-konwertery-unicablescr-10-pytan-i-od replydzi.html Ultrabox + 4k decoder supports unicable I / II. The above-mentioned mutliswitch according to the store's service: "Multiswitch 9739 should be enough in your case. On two outputs you receive 16 Unicable signals (4 for Unicable I and 12 for Unicable II), while on the other two you receive" standard "signal SAT with a possible DVB-T signal. 9739 can work with both LNB quad and quattro. Please remember about additional 9739 "power supply. So if unicable II doesn't work then I will use unicable I with 4 heads (hard). One thing I don't understand is how he will get so many outputs from 4 signals, but I will not think about it and replace the converter with a quattro (low cost and I will be able to expand it, if I would like another multiswitch).
    I do not close the topic, if I install the equipment I will share if it works.

    See the video from the tests of this multiswitch. Somehow you did not knock down the switching speed and at one point he announced himself. The theory that the decoder is tuned in to the channel higher and the channel lower is also pulled. And if I don't switch channels up and down in turn, what?

    Well, maybe some alternative? How is this best connected? I have such a decoder and I will not change it over the next 2 years (contract), for now I have the usual 2xlegacy installation.

    I don't urge you to do anything. I would buy an ordinary unicable Inverto, but if you have money, try it. Basic question, will you record 3 channels at the same time?

    Maybe it's a stupid idea. I will definitely record 2 channels (I wanted to, but it wasn't possible). 3 this probably won't happen.
    Well, I really wonder if it is worth investing so much. There would be no need for power supply after the convent, with a multiswitch I would have to have the power supply connected all the time, which generates losses when not watching TV (small, but always).
    Ok, yet the question is which cable is best to buy so as not to overpay and that it is of good quality? It will be no more than 2 meters outside, the rest will go into the building via the chimney.
    I found something like this: Televes T100 Full CU HD cable with 1.13 COPPER 1m 2141. The vein and copper screen, you will not be bad?

    He is 10 years old and from what I remember it was the cheapest, probably copper-plated. I don't complain about the reception quality (signal strength / quality in good weather 80/75). Well, it's probably worth mentioning, moreover, they write to use unicable technology cables of good quality.

    A lot of different things are written ... If you want to have peace, buy black with a 1.13mm vein and a dense braid. With such simple installations, you won't notice the difference. Televes is a very good company. If you buy white you have to reckon with the fact that after a few years it will crumble outside.

    Ok thanks for all the help. On the advice of andpol 33, I bought an inverto converter without playing with any switches, power supply, etc. Unfortunately, the installation was so old that it was not without an angle. ;) . I also exchanged the cable (but only 1 episode to the tuner with unicable) and really without any difference, so I leave the rest of the cables.

FAQ

TL;DR: On dCSS kit the first 8 user bands are active by default, and “Ultrabox only supports the Unicable I standard (EN50494).” Configure fewer UBs for Ultrabox and match UB order with the LNB/multiswitch. [Elektroda, netTv, post #17233858]

Why it matters: For nc+ Ultrabox 4K owners planning Unicable/SCR with multiroom, this explains LNB vs multiswitch choices, wiring, and setup to avoid costly misbuys.

Quick Facts

Does nc+ Ultrabox 4K support Unicable II (dCSS)?

Ultrabox 4K operates in Unicable I (EN50494). You can still use a dCSS LNB or multiswitch, but keep it in EN50494 mode. Those devices expose the first eight user bands by default. “Ultrabox decoder only supports the Unicable I standard (EN50494).” [Elektroda, netTv, post #17233858]

How many user bands should I allocate to Ultrabox, and why?

Allocate only the UBs you need on Ultrabox, then leave the rest for other Unicable decoders. dCSS hardware typically serves the first eight UBs by default. Enter UB frequencies manually in Ultrabox and keep their order identical to the LNB or multiswitch programming. [Elektroda, netTv, post #17233858]

What’s the simplest reliable setup for Ultrabox + two WiFiBox decoders?

Use a Unicable+Legacy LNB, e.g., Inverto with 1 Unicable output for Ultrabox and 2 Legacy outputs for WiFiBox units. This avoids a multiswitch and extra power supplies. A user completed this build and reported it worked fine without additional hardware. [Elektroda, Remus, post #17248068]

Should I buy a Quattro LNB and Johansson 9739 multiswitch instead?

Only if you truly need many Unicable outputs or distribution features. For Ultrabox + two legacy decoders, a Unicable+Legacy LNB is cheaper and simpler. A user abandoned the multiswitch idea and confirmed the simpler LNB solution worked well. [Elektroda, Remus, post #17248068]

Does the Johansson 9739 multiswitch require a separate power supply?

Yes. The store advised that multiswitch 9739 needs an additional power supply. Plan for continuous power if you choose this route. This is one reason some users prefer a Unicable LNB only, to keep the system simpler. [Elektroda, Remus, post #17234800]

Will Unicable II improve channel zapping speed on Ultrabox?

Reports do not show dramatic gains. One tester noted the speed did not impress, and questioned theories about tuning adjacent channels. Expect incremental, not transformative, zapping improvements from Unicable with Ultrabox. [Elektroda, andpol 33, post #17234859]

Can I use a Wideband LNB and still feed two legacy decoders?

Not easily. The challenge is finding wideband gear that also provides legacy outputs for standard decoders. Forum feedback questioned where such a converter exists for that mixed use. Prefer a Unicable+Legacy LNB for this scenario. [Elektroda, andpol 33, post #17233951]

How do I configure UB frequencies for Ultrabox on a dCSS LNB or multiswitch?

  1. Connect the dCSS Unicable output to Ultrabox and open advanced single-cable settings.
  2. Enter only the UB frequencies you want Ultrabox to use.
  3. Match the UB order with the LNB/multiswitch profile to avoid conflicts. “Ultrabox + has been poorly designed in this respect.” [Elektroda, netTv, post #17233858]

What recording capability should I expect with Unicable on Ultrabox?

Expect to watch one channel while recording up to three different channels. This is the vendor-stated capability for Ultrabox in a Unicable setup. Users cited this as the tested and supported mode. That gives you 4 simultaneous streams (3+1). [Elektroda, andpol 33, post #17233475]

Will upgrading my coaxial cable noticeably improve reception?

Often not on simple, short runs. “With such simple installations, you won’t notice the difference.” For durability, use black RG6 with a 1.13 mm copper center and dense braid outdoors. Televes-branded cable was recommended as solid. [Elektroda, andpol 33, post #17235113]

What if Ultrabox doesn’t recognise Unicable II profiles correctly?

Switch the decoder to EN50494 mode and enter UB frequencies manually. Ensure the UB order matches the LNB or multiswitch configuration. If the order mismatches, channels can fail or map incorrectly. “Ultrabox + has been poorly designed in this respect.” [Elektroda, netTv, post #17233858]

Can I reserve some dCSS user bands for multiroom decoders?

Yes. In Ultrabox’s advanced single-cable menu, enter fewer UB frequencies than the device offers. Leave the remaining UBs for other Unicable-capable decoders in the system. Keep UB ordering consistent to prevent conflicts. [Elektroda, netTv, post #17233858]

Is the GT-SAT GT-S3dCSS24 LNB a good choice for Ultrabox?

Ultrabox works in EN50494, so it can use a dCSS LNB in Unicable I mode, typically on the first eight UBs. Brand quality wasn’t assessed in the thread. A known working alternative was an Inverto Unicable+Legacy LNB for this use case. [Elektroda, netTv, post #17233858]

Can Johansson 9739 work with a Quad LNB, or only Quattro?

According to the store information relayed in the thread, the 9739 can work with both Quad and Quattro LNBs. If you pursue it, confirm with the vendor and plan the required power supply noted for the unit. [Elektroda, Remus, post #17234800]

What real-world outcome did users report after simplifying the install?

A user replaced the plan for a multiswitch with an Inverto Unicable+Legacy LNB. They also swapped one cable segment and reported no reception difference, so they left the rest intact. The system then worked and the topic was closed. [Elektroda, Remus, post #17248068]
