Richard,

It is not clear just what you were trying to demonstrate, but there was
no obvious connection to Rr. Maximum gain is unrelated to Rr.

Were you looking for validation that you correctly loaded the numbers
into EZNEC?

Looked OK to me.

(OK, so my trolling is not as professional as yours, but I tried.)

If you really are concerned about Rr, then consider the following.

Rr is defined by the equation:

Total power radiated = a*I*I*Rr,

where I and Rr are referred to the same point on the antenna.

For short antennas this reference point is generally taken as the
feedpoint, which is also the current maximum point. There is no loss, so
all power into the antenna is radiated. Therefore the Rr for each of
your perfect world, zero loss examples is proportional to the feedpoint
resistance. Apply an appropriate scaling factor (a) if you want the
correct numbers.

Did you have a question about something?

The bottom line, of course, is that none of this matters in a perfect
world with zero loss. All the power input is shot into space. Please let
us know where we can find that perfect world :-)

So much for theories of Rr being modified by loading. I would
appreciate other effort in kind to correct any oversights I've made


Hi All,

Nothing to offer? I didn't think so. :-)

Well, to enlarge the dialogue (but still reject those who prefer to
change the topic to what they CAN prove), any -ahem- "explanations?"
