Could you support a vertical 1/2 wave for 160 with aballoon?
You could end -feed it at the base through a 1/4 wave of 450 ohm
But feeding a half wave vertical with the base near the ground
> still results in substantial ground losses without a radial system.

And this statement is based on what? Publications, measurements,
modeling?
I have built a number of 1/2 wave verticals without radials and compared
them to 1/4 wave verticals with radials. They are
indistinguishable in performance and certainly do not exhibit
substantial ground losses AFAIK. The PAR electronics 1/2 wave
end fed antenna seems to have a good reputation, unlike some
GAP verticals.
However, I don't recommend feeding it through 1/4 wave of 450
ohm open wire line. I just use an LC matching network.
