Tom,
The Carolina Windom uses a section of balanced line between the antenna
and coax. Most off center fed Windom type dipoles use a balun an direct
50 ohm coax feed. Going way back to the 20's the original Windom used a
single wire to feed the long part of the antenna.
As you do your research, you will see that there are a number of ideas as
to how to put this thing together. Some variations in the exact placement
of the feed point along the antenna and also as to what balun to use: 4:1
or 6:1 are the most popular choices. The guy who puts his feed point at a
particular point and uses a particular balun has all the scientific proof
that he is right. Of course the guy who puts his feed point at a different
point with a different balun also has proof that he is right. Do your
homework and make your choice.
Nice thing about a off center fed dipole is that it is broadbanded and you
will need little tuner use on it's main bands of operation. Had a 80-10
meter one up here for a while and liked it except that it gave me some RFI
in the shack on 80 running 500 watts. Perhaps I could have solved the RFI,
but since I like 160 meters, I went back to my trusty loaded, shortened
dipole for 160/80/40. Like David said, a loaded dipole for multi bands is
another good choice.
Good luck, I'll look for you on 160 this winter.
