I guess I'm the only guy who would like to hear more about OCFs probably
because I'm half considering putting one up again. Maybe this time armed with
more knowledge, a better balun, and a couple of common mode chokes I'll have
more luck.
I'm pretty curious about the results of Rick's experiments with a dozen
different ones but maybe I'll have to wait for the book.
Incidentally, no one needs to get a book to study up on transmission line
transformers. Just get the spreadsheet, TLcalc.xls. Type in a few parameters
and it will give you an instant education, showing the impedance every 10
degrees down the line. I love this spreadsheet and I see there is a newer
version.
