It's only sky that needs two cables. Other wideband (unicable) LNBs
connected to the appropriate tuners only require a single cable, and the
signal can be split.

Because these unicable LNBs don't steal the DAB/UHF frequencies it's
possible to combine the signals from terrestrial and satellite in the
same cable.

The cynic in me says Sky have adopted a bespoke system to tie people
into their Q service. Its no longer just a matter of swapping out a box
at the end of the cable as can be done with a "traditional" LNB.
