I recommend a Winegard HD7697P antenna, Fry's Electronics is showing the antenna as being in stock at both stores in Phoenix Az. Fry's part number 5939584. Aim the antenna in the direction of South Mountain , about 196 degree magnetic compass. . How many Tv's are/will be connected?? I recommend new coax connected to the antenna and on the outside of the house. . Also --> How many Tv's are/will be connected?? Here is how to aim Tv antennas ,
