I recommend aiming both antennas at about 340 degree magnetic compass , in between the two groups of stations , the tv stations are strong and both groups will be received. If you will like to do it with one antenna then I recommend a Winegard HD7697P antenna , with a Antennas Direct CPA-18 preamp. Also check out Channel Masters newest DVR ,
