Richard Hi Jack,

Richard This is an aspiration on par with monks seeking nirvana. The
Richard two illustrate it is the path, not the destination that is
Richard meaningful.

Richard There is a very clear point to be made that unless you
Richard elevate the dipole, any 50 Ohm characteristic you observe
Richard will more ground loss than radiation resistance. This is
Richard reasonable only in the sense of ease of tuning and the
Richard reductio ad absurdum is bliss can be found in a dummy load.

Oh, I see your point here. What you're saying is that my dipole is so
far from the ideal that reaching 50 ohms won't mean anywhere near the
same thing that it does to the ideal case. That begs the question,
then -- if not 50 ohms, what is the best value for my particular
configuration?

Jack,
You may have a misconception about impedance here. Making the antenna
resonant is not going to make it 50 Ohms. Extrapolating your numbers, it
looks like resonance would be at around 6.9 MHz, and give you an impedance
of something like 12 + j0. Might be a good match to a 1:4 (not 4:1) balun,
but you would have to see what happens on the other bands.
