Its pretty simple to do in EZNEC, Bill. All you need to do is to
model two yagis at the appropriate heights above ground, and
then drive each one with a 1 amp current source. EZNEC lets
you specify the phase angle of the current sources, so you can
set the source for one antenna to 0 degrees, and then
change the phase angle of the 2nd current source as you
wish to see how the phase shift between the two yagis
effects the elevation pattern.
