Very interesting concept. Someone really thought that out, and it appears
workable at first look.
It would probably make a great 1:1 single band VHF or UHF balun, unless I
missed something.
I see it a little different for HF. While it would work (at least it appears
correct to me), a current balun would maintain balance just as well, be
wider bandwidth, cheaper, and have less loss. I think I'll stick with my
large ferrite bead baluns for HF, but that sure looks good for VHF and up. I
think it is a great idea for VHF/UHF, where beads won't work well and 3/4
wave transmission lines are not physically long.
Thanks for posting that, it is an interesting concept.
