wire it all up correctly with a quad lnb ???

[alfa155btcc]

Hello to All On This Forum,

I previously posted a thread asking about using or not as it was in the end a 4 way splitter, well after you all telling that this could not be done, I took your advice on board and tried it the way it was before ie 2 way splitter and then used a loopthrough on one of my stb`s, Guess What it Worked, so i did`nt need to wire up a quad lnb after all.

Saved me alot of time and money, who would if thought it eh ?????

I think on my previous thread i was not give enough time to explain myself properly and to top it off my thread was closed, thanks for that guys.......

Splitters still have limitations, though - but if it is doing what you want it to, that's good enough

 

[Robbo]

It will NEVER work properly though. But if your'e happy with it, that's the main thing.;)

Nice result.

Nice to see you are happy that it is doing what you wanted, however that still doesn't make what you have done the correct way. Technically it is less than perfect and thus prone to possible problems especially if you use more than one stb at a time, also a loopthrough is yet a further restriction on the set up.
As this is a self help forum leaving incorrect information around for others to follow without making it clear that it is wrong is only leaving the forum open to legal problems when hobbyists invest what are large sums of money based upon the information contained within the forums. Unless we make it very clear to people as in your case that what you are attempting is not the correct way we are open to possible litigation and therefore stand by the decision made to close the previous thread containing incorrect information.

Some things to understand about LNBs:
1. A LNB is 'programmed' by an STB to receive a specific channel off a specific tansponder. If you loop through to a second tuner (in the same or different STBs, and then try to receive different channels on the two tuners, it might or might not work depending on how the channels share relevant tuning characteristics on the LNB. This means that sometimes the second channel will fail to tune in properly. The aim should always be to connect each tuner to its own LNB. Multi-LNBs can help to achieve this without an additional dish.

HOWEVER

2. Multi-LNBs also have restrictions. They typically share common voltage rails, and when connected to multiple tuners can sometimes suffer from interference between the different LNBs. I have found that the official HD receiver in the UK causes huge interference with the other LNBs connected to the same multi-LNB. So also be aware of this.

3. The correct and failsafe way to connect multiple tuners to a single dish, with multiple LNBs pointing at multiple satellites, is to install a multiswitch, but these are really expensive. They isloate each LNB and ensure continuous power (as I understand it) to all LNBs. These devices are really high quality diseqc switches. See this link:

Yes.

For the benefit of the wider readership, it might be useful also to see the original Thread

The limitations of this compromise solution will no doubt become apparent in due course ........ ;)
