I'd suggest that the problem is a combination of a weak signal and interference from KOAM.

Your pair of Y1713s can be stacked horizontally about 34" apart to null KOAM and still add 2-3 db to KQTV. http://www.hdtvprimer.com/ANTENNAS/ganging.html

When combined with a CC7870 they will add by about 2 db. If this arrangement works your problem is interference. If not, you'll need more antenna gain.
