I have had my Mitsu 55 inch Diamond series for about 3 months now, and I must say, I am amazed. My question is, I live in a apt./condo area, and I am having trouble with every antenna I have tried to pick up OTA in HD. Anybody have any suggestions. I have tried the on the dish antenna, and the Recoton indoor/outdoor amplified, and still nothing. I am using the Mitsubishi Direct TV set top decoder box, and I just need to get a good antenna to go along with it. But I do not have a roof to mount an antenna on. Just a patio.
