(first of all, I'm for the moment *assuming* the above to be true)
Seems like they would have trouble picking out stuff coming from
one specific tv set, especially in the case of apt/condos where there
would be a lot of tv sets going within a small physical area.
Also, an antenna amplifier should prevent anything from going
back out the antenna.

(no I don't have an earth station)
