If your terrestrial receiver is >3 years or so old, you may want to look into a newer tuner. The chip sets in the newer tuners have better multipath rejection/equalization, and can pick out the digital signal better from the ghost signals. In digital more signal is not necessarily better if you have multipath. In multipath, the signals that arrive from an indirect path can cancel some bits when mixed in with the signal from the direct path, making the decoding very difficult. This is called the "digital cliff". It either works, and you get a clean picture, or not picture. I fyou are looking over trees & hills, you have multipath!
I am in the L. A. Ca area and have a clean view of Mt. Wilson (the main broadcast point here), yet with the early tuners only could receive 3 or 4 channels, due to multipath. A new tuner two years ago, and now get 28+ channels with no change to my antenna. Good luck!
