I would be interesting to know if it is possible to design a special
balun that can balance the two unequal parts of the OCF with a "no
common mode current" in the feed line but still with a galvanic
connection to avoid static build-up.
Sure. k9yc.com/RFI-Ham.pdf has a bunch of simple designs. It's called
a common mode choke. To confuse people, some call a common mode choke
a current balun. BUT -- most commercially available "current baluns"
are pretty poor.
