less naive than cloaked land based transmitters might be.
That's just ridiculous to suggest that people are going round and installing transmitters with cloaking devices across the country.
Seriously high altitude weather balloons would be a better answer.
It may appear to be a better answer, but seriously have a look at pictures of masts and the humongous sizes of these masts that are placed in the middle of nowhere. Now from any point where houses are situated, all receivers can be pointed in that direction and tilted depending on where on that mast their transmitted signals are, because these masts have numerous transmitting devices on them as well as relay receiving equipment.
If you were told, tomorrow that space satellites were a hoax and the governments come clean...you would then not be arguing this case...you would be simply saying...hmmm, yeah, it is just high transmitters and communication ships and AWAC type aircraft, balloons and so on.
Marconi was knocking signals over to France in the early days when radio was in its infancy.
