I missed this posting the other day. Just saw it.
You have to be careful with YT, using stacks with close spacing.
If you plot a stack of two antennas even one foot apart,
YT will still show a 3 dB gain over a single antenna.
I think there's a caveat
in the documentation somewhere to that effect.
I guess the program's main intended use is for predicting
the effects of irregulat terrain, rather than accurate stack
modeling.
