If you use the right Satellite LNB (quattro I think they're called), you
can get a box which takes the 4 inputs and allows a large number of
satellite boxes/Sky/TVs to share them.

A multiswitch ideally it'll also take terrestial TV, DAB and FM as well as
the four feeds from the LNB and send the whole lot down each of it's outputs.
Some multiswitches can drive a Quad LNB to get the right signals on the right
inputs others require the connections to be be correct and the use of a
Quattro LNB.
