<Also, I try to avoid short element segments. FWIW, my SWR curves closely
<match NEC2.

##  Do u mean the tubing scheduled used ??  That wont make any difference to the
electrical design.  The tips just have to be tweaked to resonate them where the 
softeware
wants them.   You will end up with a stronger mech design by not using swedged 
eles, and
instead starting at the tips with .375, then .5 then  .625 etc.
