simple or accurate??? you can't have both. in this case you have ignored,
among other things, that the capacitance between each infinitesimal part of
each vertical piece to the rest of the world is different. therefore your
transmission line sections are not uniform from end to end as needed to use
the classical transmission line formulations.

But, since the 'classic' antenna calculations are only
approximate, how
much additional error would Reg's method entail, if any? I
think the
"simple -vs- accurate" thingy is one of the things that Reg was
getting at.
Very 'fiddly' (Hey Reg! I picked up an 'English' word, or would
that be
an 'UK-ism', sort of like an 'American-ism'?)...
