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.
Where do I measure the 34" distance from on each antenna? The balun? Or elsewhere?

Also, what do I use for a horizontal boom?
