If you research the origins of that urban myth about bumblebee flight 
defying the laws of physics you'll find some interest parallels with 
antenna modelling!

In short, the supposition that a bumblebee can't fly was based on a 
simplified aerodynamic model that does not apply to the type of airflow 
over a bee's wings. Use a more complete model which takes account of the 
fact that the bee's wings encounter dynamic stall on every down stroke, 
and flight becomes possible. The bumblebee *does* obey the Laws of Physics!

It's no different with antenna modelling - make false assumptions and 
apply inappropriate or incomplete modelling, and you'll get silly answers.

In the absence of any rigorous field strength measurements, it's only 
antenna modelling that has given W7WHY an authoritative answer to his 
question about the QST article.
