How does Sky Q get several channels through one cable?

I can't but a fibre LNB can do that (well one fibre for signal an a coax
for power)

When Sky HD came
out, we had to add a second cable to the dish to get two channels. But Q
does not need 6 cables to get 6 channels.

Q needs two coaxes, one for H polarized and one for V polarised, each
cable carries the entire 10.7 to 12.7GHz band, rather than selecting the
upper or lower "half" like a universal LNB does.
