[TowerTalk] Carolina Winsome and vertical radiator question

[Kelly Taylor]

It appears the matching unit between the ends of the Carolina Windom is
W4THU's secret blend of 11 herbs and spices, if you will.

Likely to prevent people from home-brewing the CW, it's never clearly
explained just what, if anything, might be different about it vs. a standard
4:1 balun, nor is there any indication any of the other units on his website
are similar in construction.

But the site does make it pretty clear the antenna relies upon common-mode
current on the outside of the coax between the antenna and the choke 24'
down the coax.

Can't, and won't, say I blame him for trying to keep proprietary information
proprietary, any more than I blame KFC for locking up the recipe. (I do
blame them for turning KFC into crap, however.)

For the RW OCFD, there doesn't appear to be a reliance on common-mode
current on the coax, since no choke is specified.

So, the question is: while a 4:1 balun is the correct choice for an OCFD,
would it necessarily replicate the matching unit in a CW? If it's designed
to prevent CM current on the coax, maybe not.

I don't know the answer, which is why I'm asking.
