[TowerTalk] 80m vertical size calculation

[Wes Stewart]

Don't think so.

IIRC the OP said the tubing diameter went from 4" down to 1".  If you modeled in 
NEC with stepped-diameter correction to get an equivalent uniform length and 
then took a percentage before changing back to tapered, you might get there.  
But if you can model in NEC, why not just work out the change there?
