I suggest a Winegard HD7697P with No preamp. I suggest have the antenna connected to the one Tv , no splitters. .If more then one Tv is to be connected at other locations then use a distrabution amplifier such as the ChannelMaster CM3412 or CM3414. . Do not use the preamp it is likely to be overloaded by the strong signals of KWKB , KIIN , KFXA . Direct the antenna at about 340 magnetic compass. Here is how to aim Tv antennas ,
