The most important measure of an antenna is the amount of field intensity it
can produce at a given distance in a given direction, per watt of applied
r-f power. So far you have written nothing specific about this for the
"Unwin" antenna.

Note that a transmission line feeding a 20 dB series attenuator attached to
the input of a 100% efficient antenna will show very high return loss to the
r-f source ( 40 dB plus the twice the cable loss). But that antenna system
will radiate little of the available EM energy, nonetheless.

Could you please comment on the measured or at least the calculated
RADIATION CHARACTERISTICS of your antenna, compared to a matched 1/2-wave
dipole at that frequency (or an isotropic radiator), and tell us how you
arrived at them?

If you can do that, and your results can be scientifically duplicated by
others, you will have removed the source of a lot of the skepticism you read
here and in your similar threads on eHam.net.

Otherwise it will be "more of the same," which (let us hope) is or should
not be your goal.
