Query: Didn't work for me

I gave this a try, based on some favorable reviews, but was very disappointed. In my house (metro DC area), I got weak reception of analog channels, and NO reception of any of the HD digital channels. The product didn't even come with any documentation to help me troubleshoot and try to improve the performance. After an hour or so of tinkering with angles, positioning, etc... I gave up. At least in my home, in my local broadcast area, this antenna was worthless for picking up HDTV broadcasts.
