I see different results then what your suggesting here... a DIPOLE at
136' (what I have) out performs a 4 SQ for all angles down to about 4
degrees! And not by a small amount. Possibly their model is not correct?
or I am not using it properly. "......
The model included with EZNEC contains no wire losses, no transmission
line losses, and no near field ground losses, and assumes average flat
ground.
