Mike,
I am late in picking up this thread, nevertheless I went through the OCF
dipole fever, modeled like mad (EZNEC), read the literature, and like all of
our antennas you have fans for everything from the proverbial bed spring to the
OCFD.
IMHO: although they will claim multiple band resonance, the models show "close
but no cigar." (I'll be slammed on this for sure.
Then too, those commercial versions have baluns to make it match, and in the
end, the recommendation is to use a tuner.
If you would like to OP on 30 meters, then make a dipole and hang it as high as
you can.

Gang,
It's been way to quiet here.
With fall only a week away and winter not too far behind, it's a great time for
antenna work.
I'am going to out up a off center fed dipole.
After reading pages after pages of information about this antenna it seems to
work differently depending to quite a few factors.
Such as how high up, gauge of wire, insulated or not and of course the feed
point.
>From what I've read, 137' wire. Short end about 42'
(All lengths are for example only!)
Now according to W8JI, he suggest the short end should be 24'
Has anyone built a OCF dipole to W8JI dimensions?
According to his web page, the above feed point will get me 30 meters. I'd love
to put my Argonaut VI on 30 meters this fall.
I've got the wire a good 4:1 current balun and a rainy Sunday.
