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. 73 Tom _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
