Because the loftbox or other amplifier will have three separate
inputs.
As the others have said, if you're distributing using a loftbox, have
three separate cables going into the loft and into the 3 inputs on
the loftbox and then distribute the combined signal throughout the
house.

And if you put a spare cable (or 4) in now you can also pipe satellite

through the (right sort of) loftbox

How can you pipe a quad lnb through one output? (That seems to be the
implication)
If such a device exists, I'd be interested in a link.
