[TowerTalk] TowerTalk] element tapering calculation

[PY1NB - Felipe Ceglia]

Hi Steve,

Thank you for replying.

Does it reverts tapered back to single wire?

I want to model my current 20m tower + 40m moxon + 20m yagi to see how can
I load it as a vertical for low bands, so I want to move from tapered to
single wire as well.

73,
