To test my HD8200u and Channel Master 7777 preamp, I hooked it up to a tivo roamio at a height of 6' and am receiving multiple markets at 80-100 miles away. Aimed towards 129 degrees, I receive ABC 27.1 from Harrisburg, PA, ABC 7.1 and CBS 9.1 from DC, and some closer stations. At times, it'll pull in the big 3 networks from Baltimore as well. So I was looking forward to sticking the antenna on my roof, and was shocked to see TvFool reports better signal at the 6' level. The DC stations appear to 2edge at 6', and in the Troposphere at 30'. I've read all I can find, and don't understand this. Can someone shed some light on this for me? Thx
