Thanks for the advice guys, much appreciated.
I have the DB4e and the y5713 on separate j-poles, attached to a 6x6 post (deck pergola support beam) about 15 feet above ground. I also have the RCA amplifier as suggested (which made a huge difference!!) Both antennas are pointed SSW (just a hair to the west) for the best reception. When I first added the y5713, I had it temporarily affixed 2 feet below the DB4e. When I bought the second j-pole I put it just above the DB4e. When I did this I lost channel 5 and gained channel 9, which is fine because they are both NBC (and better reception). The problem is, now channel 7 (ABC) is pixelated and choppy. Did I create some interference? I figured moving the antenna higher would simply make everything better....It is sitting basically right on top of the UHF antenna.
