I am trying to get the best reception with a ClearStream 4 that is in my attic, and I am just 20 mins N of Greensboro. We would like to get (and typically can get) some of the stations from Roanoke VA, however when I point my antenna N/NW, some of the Greensboro and High Point stations have difficulty, specifically 2 and 8. Any help would be greatly appreciated!
