Many movie theaters provide small receivers for the hearing impaired.
Some brands use this range. I could sit outside of a theater and hear
all
of the movies playing.


I useed to be able to do the same thing with a regular AM radio.

The drive-in movie theatre that was around here at the time broadcast
their
movie sound over the regular AM broadcast band (with very low power) so
that
you could hear the movie on your car radio (after all, some people
destroy
some of the drive-in speakers).

The result was that I was able to hear the movie on a regular AM radio
while at
a nearby restaurant.

That was available around here too for a while. One drive in actually
broadcast
AM Stereo! They had just put in FM Stereo when they folded up.

I remember somewhere the system used coaxial cables that had 'holes'
stripped
in it for a specific amount of RF leakage as opposed to putting up antennas
that
would beam a signal, possibly way to far.
