The only amp that worked for me in my mixed signal location (extremely strong and extremely weak signals from the same direction) is a discontinued model from Winegard that should be able to be found on e-bay; the DA-1018 (18db gain). There is also a DA-1036 (36 db gain), but it overloads easier due in part to the higher output.
