Mailman's antennae farm is LOS (line-of-sight), 18 miles away. He can see them in the out yonder. Very powerful signal strength.
My 80-mile-away Austin and San Antonio stations are mostly tropospheric ducting, and come in quite strong, except on those rare, wierd, changing weather, heat inversion days. But, only for a couple hours. Kinda like signal loss with satellite on rainy days.
Then, there's the ion-layer skip conditions. When I get those, usually in the mornings, it really reaches out. Sometimes get Louisiana, Florida, and Cleveland. Confused me at first. Was getting weather reports that didn't make sense, from funny-sounding places, like *something* Bayou...
