Our college radio station ran 10 watts to a 3db gain antenna on top of
one of the dorms. The dorm was only 3 stories plus attic, so the
antenna was maybe 40-45 feet in the air. Good coverage was about a 2-3
mile radius with a typical portable receiver (or car); an external
antenna on the receiver obviously extended that.


Ok, if you are talking about 500 milliWatts, how do you get 100 feet
from that?


I concur with the 100ft number with 500 milliwatts.
If everything is right you can get a little more, but don't
rotate the radio or move your body to the wrong spot.
I have a transmitter that is switchable between 500mw and 1 watt.
I might be able to get 200 ft but the radio needs to be held just right.
It works fine around the house and yard with 6db of attenuation before
the rubber ducky antenna.
