I suggest a small single antenna solution. A Winegard HD7000R antenna mounted outside on the satellite tv mount. Aim the antenna at about 350 degree magnetic compass. Yes the HD7000R antenna will receive the channels you have listed. plus many more. A amplifier will be needed , what is the make and model number of the amplifier you have?? Here is how to aim antennas ,
