UHF Roof-top Antenna Range

[Eyedox]

What would be the farthest range of a UHF antenna for OTA HD signal reception? Let's assume a large, roof-top mounted, directional antenna with a booster, over flat & open terrain?

100 miles?

There's a guy that lives in SIOUX FALLS, SD (which borders Minnesota) who is claiming he can receive KWGN DENVER, CO (WB). Yeah .... right! He posted a report on www.hdtvpub.com.

i have heard of people pulling signals from 75miles away....

If the topography is right-ie flat enough and the antenna high enough it is possible. when I was a kid, my Grandparents lived in northwest Michigan, about 20 miles east of Manistee, we would watch the Greenbay Wi station. The signal would have to come across Lake Michigan.

I saw a Web sight some where a guy was pulling stations in from hundreds of miles out -something callled TROPO? I see if I can find it again and let you know.

Do some searches on TROPO Induction Some of the best place for Trop are the Midwest and anyplace where large bodies of water- IE flat places..
