Hi, it's a little more complicated than that. When the house was built, just over a couple of years ago, I had an audio-visual guy install a satellite cabling system. This works as follows: The LNB is, I believe, a Quattro LNB, not a Quad. This has 4 fixed outputs, being the four quadrants of the satellite signal:
1. Horizontal polarisation low band
2. Horizontal polarisation high band
3. Vertical polarisation low band
4. Vertical polarisation high band
These are sent to a Multiswitch (Delta Electronics Multiswitch MS 5016 N) where they are combined and sent out to 16 separate outputs (I use 14). Pairs of these are sent to 7 rooms, where they act as normal satellite feeds, so Sky or Freesat boxes can be connected in any room as a normal dual feed, with full control and the full range of channels.
What wasn't realized when the dish was installed (to an unfinished house) was that the Eurobird satellite was not being picked up well.
I have just noticed a comment on Satcure (
http://www.satcure.co.uk/tech/lnb.htm) that says "No Quattro is manufactured to fit a Sky minidish - it always requires a (roughly) circular dish". It is possible this may be the problem, as I have an oval dish?
Getting back to the "skew", this sounds a fairly easy thing to adjust, off a ladder maybe?
