I have a CM3671 at 30 feet high. About a 30' run of RG6 to a MyHD120 computer based TV card. This tuner is more sensitive than the channel scanners on 2 different TV's. I am 60 miles from the CBS, ABC, NBC, Fox towers in NYC. Those are the channels I want to get. The tuner card is picking up only ABC 7.1 but then shows no signal on it's graphic and no picture. I've incrementally rotated the antenna but get no better signal. Rotating enough I get channel 30.1 out of Hartford, CT, 65 plus miles away. I do have large, high trees in my yard. One other thing that might have consequence; I installed the antenna upside down. Is there any help for this situation?
