NM5G:
 >Apparently I need to model the two antennas to find the difference in
phase angle in degrees, then add the appropriate amount of coax to offset
the difference.

         Stacking patterns are not adversely affected by small phase
differences.

"P.S.  For example, assuming phase shifts of 0, +10, and +20 degrees for the
3 antennas going up my tower, gain only changes by a negligible
-0.08 dB and vertical beamwidth decreases by a negligible 0.1 degrees."
