[TowerTalk] Carolina Winsome and vertical radiator question

[Steve Hunt]

Here's the corresponding schematic if a 4:1 unun is used instead of a 
4:1 voltage balun.

There's a small *drop* in the CM driving voltage compared to a 4:1 
voltage balun. If I had reversed the unun connections to put the braid 
on the long leg, there would have been a small increase.
