3 LNBs 2 recievers signal problem

andiks

Hi everyone!

The strange problem we have is as follows:
First the kind of system setup we got:
Two dishes on one two quadro LNBs on second one quadro LNB to get 13E, 19E and 28. Which are connected to Diseqs to distribute signals to two receivers. Everything is kinda OK but..
One receiver looses signal for some channels (not all just some) when other receiver is switched off or switched to another satellite. This is so annoying..
Where could be a problem??
Thanks,

wod

you dont need to use quattro lnbs as these are for multiswitch systems

ordinary quad lnbs would have worked fine, is this what you mean ?

There can be a problem with some Quad LNBs (I presume you mean Quads), whereby they don't seem to be powered by all ports, try experimenting by changing the ports of the second switch, so if you have them connected on 1 and 2, try 1 and 4.

Sorry, yes I mean quad LNB.
So, you mean all ports are not powered?
Will try to switch them..

Thanks,

Did mess around with ports and it didn't work really
But if problem is in LNB, then why one receiver works well but another doesn't?
And when one receiver is ON the second receiver gets all channels as well.

Well I've never personally had a problem, but I know that some have.

Just out of interest, which make of LNBs are you using?

andiks

Ebay made
Does it sound bad?

Robbo

Ebay don't make LNBs.

When one receiver is powered off and you lose channels, are they from one satellite or all satellites? Also try changing the ports on the diseqC switches.

I think your Problem with place of position LNB

andiks

I did try to swap ports on Diseq and LNB. Didn't change anything.
LNB position? When both receivers are ON the signal from all satellites is 99%.

andiks

I'm loosing part of the channels from Hotbird and Astra (28).

Could it be like one receiver works as amplifier?
Our cable runs not so long, 20m maybe...

hi i had a problem 6 months ago just like what your having i got some one in too look at it ,what it was some thing to do with H/V setting if one receiver is on .H. and the other is on .h. both work OK but if you try putting one on the .v . you loose the channel .this is what was wrong with mine .if that makes any sense to you .[ some thing to do with SYMBOL RATE .

andiks

Thanks for your concern..

I know what you mean.. but how it was sorted out?

I thought if I have quad LNB and Diseqs I shouldn't have problems vith polarisation..?

rolfw

That's right, you shouldn't have problems, but it does occasionally happen.

Sorted!!!
I did climb to the atic to check cables. One cable was connected together with splitter (1 in 2 out). I removed the splitter and and connected cables. And...!!! Everything works!!
Installed third receiver in bedroom. All receivers work fine now from all satellites.

Happy days..

Result!

Now if we'd had some pictures of your attic we might have been able to figure this one out
