Since your cable run is pretty long, I suggest the Winegard 7694. It should easily drive one TV, but if not, you can safely use a low/medium gain preamp since the antenna is in the attic. I would try without the preamp first though.
I recommended the 7694 because I'm assuming you aren't interested in any of the stations on LO-VHF (KHPK, KSFW & KZFW)
