We installed the Mini-max RT8000s this summer. Did it myself in about an hour.
It is an in-motion antenna and has worked well from the first turn on.
Of course, with Direct TV you will not get HD signal so must be satisfied with SD.
On our <30" LED screens SD tends to look as good as HD to me. (We do have HD at the Sticks and Bricks.)
