Just get a Dual or Quad LNB and replace current one. U dont have to move the dish.
I had a normal sky box in 2 rooms and this worked fine.
I refused to pay SKy to upgrade to SKY plus so bought 2 SKY+ units of ebay ( £30 each ) and did all meself.. took 10 mins. and using a Quad LNB so i can record and watch 2 channels same time.
The reason for having this many cables between LNB and multiswitch is that the frequency of satellite TV signals is very high (usually in the order of tens of Ghz), i.e. there is a lot of bandwidth there, and even good quality low loss coax cable is simply going to be too lossy at these kinds of frequencies. Splitting the signal over four cables means that each one needs to handle less bandwidth, hence the signals don't need to be at such a high frequency.
The LNB changes the frequency from about 11GHz to about 1GHz. That's why a normal coax cable can be used from the LNB to the receiver. A lot of satellite receive systems use just one cable. Sky+ uses two cables as it has two tuners.
In a Quattro LNB the 4 coaxs are used for the 4 ways the satellite signal is transmitted. (in two frequency bands and 2 polarities: Low/Horiz, Low/Vert, High/Horiz and High/Vert)) These are used by the satellite so more channels can use the same position in the sky.

Your solution is correct, infact you can run 4 standard boxed from one Sky+ LNB as they are quads, but how do you get two (or more) viewing cards without an extra subscription? (unless you are using the council package)
