You are easy to work with , I like that. . Have you tried putting the antenna out on the patio , up high , but no need to hug the antenna real close to the ceiling of the patio. Just get it up high and the antenna close to the edge of the patio. The dipoles and loop of the antenna are broadside to the Tv stations at about 150 magnetic compass. The channels in green are what you are after. . Read and watch the video on 'double rescan' at dtv.gov , the double rescan clears out the channels in the tuner so the tuner can do a completly new scan.
http://www.dtv.gov . The digital to analog converter will show how strong the signals are , what channels do you get now.
