Thanks for the update,
If this is your antenna (

Frankly, I am very skeptical of the HD2605 claim of "Range: Up to 125 miles*". If that antenna were mounted on top of a high mountain and had a clear line of site over flat desert terrain with no vegetation.... well maybe it could achieve that claimed range.
If you look at this antenna (
http://www.solidsignal.com/pview.asp...0Antennas&sku=), you see almost double the number of elements (which is what directs and gathers the signal and yet the claimed range is a far more realistic "Up to 35 miles...".
Your report shows nearly all stations are fairly distant and 'over the edge'. You need a high performance antenna system to provide reliable reception.
I would choose a very high gain / highly directional antenna combination like this:

I would mount those on a rotor with at least 4' of distance between the antennas, and combine them using a UHF/VHF amplifier like the CM7777 (

The goal is to receive a clean stable signal
before any amplifier is used. Amplifiers increase the level of both desired signals and noise. A weak, noisy, distorted signal is never fixed by an amplifier.
