broadcast from the Empire State building.


Hi Joe,

The long answer is No.

The short answer is that with the transmission antenna at 1250 feet
(give or take), it sees out to an horizon 25 miles away. An antenna
on the ground there would receive its signal, but you would have to
lift it as you pushed back. By the time you pushed back another 25
miles, that receiving antenna would also have to be 1250 feet in the
air. That is only 50 miles range for a very unlikely audience. You
are challenge by an additional 50 miles, which, from your perspective,
places the top of the Empire State building beneath the earth's
surface by a considerable depth. No amount of amplification will
rescue that situation.
