I think everyone understands the question just fine. But it is a
question without an answer.

But that *is* an answer!

What you are saying is that the research remains to be done.

There is no research than can answer the question any better than what
you have been given. The wave transmission modes you ask about are very
little dependent on the antenna and much more dependent on the state of
the environment. So there is no way possible to give an answer that
relates the antenna design to something that depends on other variables.


What you are asking is when you feed a bird, how much of that feed
produces crap that lands on your car based on the composition of the
feed? If the feed has more fat and less protein does that put more crap
on the car or the driveway?

I'd say, based on that, that nutrition science is better understood than
the e/m fields emitted by an antenna.

Do you understand the responses you have been given? Why do you feel
the antenna has anything to do with the modes of propagation?

If there were an answer to your question, why do you think it would not
have been answered 50, 80 or 100 years ago?
