Take a look at this folded wave monopole...

This is the design I have in mind, NO groundplane radials when used as a
stand-alone vertical monopole/end-fed.

There are warnings in EZNEC about segments not lining up
between close spaced wires. My 29 dBi omnidirectional
antenna is an example of what happens when one ignores
the segment alignment between closely spaced segments.

I have modified your segmentation to try to follow the
EZNEC guidelines and that file is attached. There is
quite a change in the results. The feedpoint impedance
went from 2.787+j15.47 to 0.7587+j22.69, the gain went
from 7.23 dBi to 3.16 dBi, and the TOA went from 6 deg
to 9 deg. I standardized on one foot per segment.

I don't really understand what you are trying to do and
am just the messenger.
