I doubt there's anything special about the 22 ft.



I've been told that 22 ft. is special, i.e.
virtually everyone can get his vertical
section 22 feet off the ground. (The original
Windom had a vertical radiating section.)


As opposed to 20 ft or 21 ft or 25 ft?

I find it hard to believe that there's an electrical reason for 22ft.
Mechanical or convenience I can believe.

Maybe it fits well with the length of their isolators, etc. and matches
a convenient pole height (e.g. isolator plus sag plus 22ft plus whatever
exactly matches 26 ft 3" or whatever the pole is)


Looking through the Radio Works catalog, the vertical radiators are
22' for 80m & 160m versions, 10' for a 40m version, 18' for an
enhanced 40m version of the Carolina Windom.

So they're figuring something, what, not sure of...
