Rather than continually posting your beliefs about *why* your Unwin antenna
operates, please post some provable evidence about *how* it operates with
respect to the fields generated by a standard and well-proven radiator such
as 1/2-wave dipole.

A matched, 100% efficient, linear 1/2-wave dipole with 100 watts of applied
r-f input power at 3.5 MHz develops a peak field intensity of about 70.14
mV/m at a distance of 1 kilometer, in free space.

How does the Unwin antenna compare to this?

If you don't know, or you do and it is considerably less than the value
above -- then probably there is little point in proceeding with your posts.
