Modeling programs do indeed include radiation from the loading coils,
provided that they're modeled as a wire helix rather than by use of the
lumped load object. EZNEC and NEC both have methods of automatically
creating a helix, making this process very easy. I believe most other
NEC based modeling programs also have this capability.

Ooops! I have not used that part of EZNEC yet so I accept I was wrong.
I will have to look a little deeper into why I was convinced that the
radiation from loading coils was not considered.

I still don't find a problem with publishing the article. If nothing
else it has generated discussion.
