Correct: you're going to get collisions.

It's next to impossible to combine multiple wideband RF sources;
you need a block converter to pull it off, and a lot of luck..
Cable companies do it by pulling every channel down to baseband and
then remodulate it to the channel you want it on, and feed it to a
directional combiner tree.
I'm thinking multiple tuner cards; why not?
