Thank you everybody.
I did go out and purchase a preamp (RCA TVPRAMP1R). I moved the antenna to the highest point on the roof, but no way to get around the trees. I am picking up a few stations but NBC WHDH is very broken up. Fox WFXT is the same. I'm going to need those stations if I'm going to watch football this year
I don't understand the difference in design and uhf vhf frequencies and such. Do you all think switching to a Winegard HD 7698P would improve my channels at all? Also saw the Winegard HD8200U Platinum HD. looks like that has better range?
Is my preamp good enough or should I spring for the Channel Master 7778?
I wish I found this forum before I bought.
