Thanks for the replies.
I guess I wasn't really clear in my first post.
I know where all the towers are in relation to my location.
I'm looking for a "wife friendly" way to receive all the SGF HD channels.
I can get FOX if I aim the antenna towards their tower on East Division (NW of me), but then I lose all the other channels coming from the Fordland (E of me) towers.
Also, I think my DB 4 is too directional....meaning, given my close proximity to the Fordland towers, I get great reception when I aim the antenna towards a specific tower, but then I don't get a very good signal from the others. Hope that makes sense. Weather and wind seem to really affect the signals too.
Could I add another DB4 (or similar) to my mast, and have one point towards Fordland, and the other towards FOX, and then combine the signals???
