Antenna TV is pretty cool, actually
(www.spacebar.news)
This is a most excellent place for technology news and articles.
80% of the US population lives in urban areas. An amplified antenna can pick up channels for many of those further out. Won't work for everyone of course.
I live almost exactly 20 miles from most of the towers in my area, if I got rid of all the trees and buildings in my way I might even have line of sight to the towers
Unfortunately my main TV is in the basement, and even with an amplified antenna I can't quite seem to pick up more than 1 or 2 channels, and I don't quite care enough to put up an external antenna on my roof.
