Beauty of FreeView tuners is they all have an aerial in and out.

Ah, so they could be daisy-chained and only the first one in the chain would
need to be connected to an aerial? That would be good.

Then pick up the wanted one - via a switch - to a local amp and
speakers.

I was hoping to avoid the need for local amps, but (as I've just said in a
different post) the drawback with just one central amp is that each room
would have the selected sound playing at the same time. That's not really
ideal.
