Re: Sattelite dish size
Helllooooo
.
Theya re called stackers, and allow one cable to run two feeds. One unit is powered, and it sends the two signals down the cable at two different frequencies.
HOWEVER, you will encounter loss / drop in signal with stackers, so it may not perform as you want it to, especally on those critical / weaker BBC and ITV frequencies.

Re: Sattelite dish size
Small.
One unit would hid nicely behind the TV - its about the size of an external USB hard drive unit.
Then the other peice of kit goes at the dish.
However, I think I have misunderstood your orignal question:
The STACKER takes TWO FEEDS from the LNB and pushes them down ONE cable, then splits the again.
It does not take ONE FEED and splits them into two cables.
I do not know of ANYTHING that does this - as a single feed from the LNB can only take one of the four frequency polarisations at a time...no good if you wnt ot watch a vertical frequency and a horizontal channel at the same time - as the two polarisation will not be able to be fed from the single LNB output.
So not even a cable splitter will do the job - again due to the single output only feeding one of the four groups at a time - and not good for receivers or LNBs if two "receivers" are both sending power down the same cables...

Re: Sattelite dish size
Why not use a 'small' distribution board?
We take all four signals from the LNB, to the distribution board, and out to as many feeds as you want.
Simples!! (but not cheap and not small).

Re: Sattelite dish size
A Quatro LNB and a "multiswitch" unit is the best thing for multiple feeds.
4 cables from the quatro, to the multiswitch.
multiswitch come with 8 12 or 16 outputs.
using a 4 output LNB and splitting the cables / signals to 5 or more receivers will not work correctly - due to the 4 groups of frequencies that the receivers look for - and can camage LNBs and receivers, especially if one receiver is using a VH (ie sky news) frequency and another on the same cable is looking for a HL frequency (like BBC2)
but if you have an offset dish, why not try an octo LNB...?

Re: Satellite dish size - other options?
Hello All, I'm just wondering, has anyone ever thought about or tried adding several smaller dishes together (in an array) instead of a huge single dish? ((...other than NASA!)) Kind Regards!

Re: Sattelite dish size
that will not work.
one "big dish" is required to receive certain frequencies.
Smaller dishes will not receive those frequencies - and so using multiple dishes will be pointless as they all will be too small to receive those frequencies.
