I recommend 2 Winegard HD7696P antennas , one aimed at about 151 degree magnetic compass and the other aimed at about 10 degree magnetic compass. A coax will go from each antenna to the location of the tv. The coaxes will be separate all the way to the location of the tv. Some tv's have 2 separate antenna inputs , if your tv has 2 separate inputs then the 2 coaxes will be connected to the 2 inputs. If the tv does not have 2 separate inputs then use a remote control A/B antenna switch , AB27RS . The HD7696P antennas should provide enough signal to the tv to not use an amplifier with either antenna. However if a preamp is needed , I recommend a

Do Not combine the 2 antennas on to one coax. Keep the antennas and coax separate. Here is how to aim antennas ,
