Excellent post Shawn.
I was concerned about this when W9AC mentioned small height changes making
big radiation angle differences at W3CRA(sk)

Also I have seen many people use HFTA to optimize stacking heights and it
does not calculate interaction of close beams properly.

Since terrain effects have entered the discussion, here's my 2 cents
(probably less) on the subject. Like any modeling program, be careful
interpreting HFTA results. See my earlier post at:
