I think some of you are missing an important point about HFTA: In some cases, as high as you can go may not be what you want to do. If you have an extreme slope in one direction, you may only want to be up 35' or so. You have to do the simulations to see. And no, I don't have multiple towers. Remember, not everyone lives in the flatlands.

I remember being at one of Dean’s presentations in Rochester, Minn., and if I recall correctly, the value in one model 
was picking the optimal height for all three tribander bands: I don’t know if it was elitism or what, but he 
didn’t seem to understand that some contesters may actually be limited in what they can put up, because when I asked if 
the flat-terrain model was showing height x as a good compromise for the three bands — for contesters able to put up one 
antenna only — his response was “but do you want to lose (these peaks)?”

Sometimes it’s not a matter of what you want, it’s a matter of what you can do.

Still, it did seem to me as though going as high as you can go and waiting for 
the propagation gods to smile upon you would be a waste of money.

I'm a firm believer modeling, as well.
I use 4NEC2, Mmana & Eznec, and I trust them too.

I'm a firm believer modeling.  I use EZNEC and AutoEZ and trust them.
