No not crazy.. You would certainly get gain but the question you have to
ask is whether it is enough to overcome through wall etc losses. You
also have to keep in mind that the signal you are using might be via
reflection rather than direct. ie the direction you point may also need
to be played with.

It would be a great talking point for the occasional visitors too!

Look online for a free or cheap old parabolic dish. Stand it against

you are able to point it to a tower and find the sweet spot, you can
find some gain there.

Am I crazy folks?
