Multi LNB Setup: Sirius 4.8 E, Hotbird 13E, Eurobird 1 28.2 E.

[proantibiotic]

Hello,

I live in Vilnius, Lithuania.
My dish size is 80 cm. I have 3 seperate LNB's.
Earlier I had configured my lnb's for Amos 4W, Sirius 4.8E, and Hotbird 13E and had no problems.
Now for a while I've been having problems with re-configuring it to (When standing behind the dish) Sirius 4.8 E - left , Hotbird 13E -middle, and Eurobird 1 28.2E - right LNB.
It seems I can connect to Hotbird satellite and to Sirius, but then i can't connect to Eurobird 1.
If I set eurobird to middle lnb and rotate the dish towards it - it works, but when I try to connect all three satellites as hardly as i try to regulate LNB I can't get a level.
So I want to ask how i must configure my lnb's to be able to watch from all three satellites, maybie there is something I'm doing wrong, or such configuration is not possible at all.


Any help would be truly appreciated

I suspect the problem is the angular spread: Your original system spanned no more than about 17 degrees, which should be fine with that 80cm dish for strong satellites ...........

But I rather think that you might be pushing it a bit to get a 24 degree spread.

There may be a way to do this, though, but you'd need to to try different dish alignments - I'm assuming for now that you are centring the Hotbird LNB and aligning for that in the same way you would for a single Sat system.

So maybe you could try aligning the dish itself to around 15 or 16 degrees and see if you can then pull in both Sirius and Eurobird 1 with the outside LNBs.Obviously the Hotbird LNB in the centre will require a bit of jiggery pokery too - and the whole exercise would only be feasible if your particular multi-bracket permits not having an LNB at the focal point. ie all three LNBs will be offset to some extent.

Yes, try and bias the dish more towards 28E, with the other two more off focus on the other side. You can do it gradually, by moving the 28E LNB in a bit at a time, then rechecking. If it still doesn't work after all that, I suspect that its not possible, and you'd need two dishes, or alternatively one that is better at multisat, like a toroidal.

I will try to do what you sugested. : )

And yes, you are right about that.
Thanks again : )
