Query: Hurts, Not Helps, Signal

I have 7 HD channels, and one of them is not coming in well (off-air antenna). I bought this device hoping that would help that one channel. It did not. Instead, it killed all of the channels except one! It actually hurt my reception. My HD receiver rates my ABC channel at "90", but with this amp inline, it is between "40" and "50", and simply won't tune in most of the time. The same can be said of my other channels. I am going to see if I can return it after writing this review. The description of this amp says it is for satellite, off-air and FM. I don't know if it helps satellite or FM, but it sure does not help HD off-air.
