The results you are measuring are certainly within the range of the
MFJ 259. As an example: a 493 ft dipole, 50 ft above an average
ground shows anti-resonance, at 1.9 MHz, and is 15,000 ohms.

Frank, that is twice that you have mentioned dipoleas a comparison.
May I remind you again that for equilibrium purposes the radiator
must be a wavelength or multiple there of, assuming ofcourse we are
considering a single radiator
To talk of a "dipole" when considering my design is totally
unreasonable.

But that is the typical input impedance of a one wavelength long
antenna (15,000 ohms).

Yes Frank but you have to remember mine is a new design. The antenna
is now on the ground
and has a resistive impedance of three figures. I anticipate that when
I put it on my 30 foot tower the impedance will drop
on top band by 50% where I will add a transformer to drop it to 50
ohms. Now on the other bands it may well not need a transformer
so I can play around on 20 M for the winter until I can achieve a good
match or place a tuner at the tower top.
As I have stated many times a radiator does not have to be straight so
figures found with a dipole are just not applicable in my case.
In fact a anti resonant impedance can be driven below 50 ohms if one
wanted to so prior findings are just not applicable.
In a month or so you will be able to put my antenna on your computor
program and check for yourself I promise you.
