Back in the '80's, I picked up a Florida station for a few hours from downtown Bridgeport Michigan! That's over 1,000 miles. I could pick up Pennsylvania stations right through Canada fairly regular, 300+ miles. I had an XG91 antenna with a rotor, around 58ft tall, and a Winegard 1db noise, 30db gain amplifier.
Bridgeport's elevation is 587ft also, and is in a "hot" area for signals.
