I'm looking to build a couple of 10 meter yagis and want to use a current type
balun (choke balun). I see the offering by The Wireman for a W2DU Current Type
balun. Does anyone on this reflector have experience with these baluns, either
good or not-so-good experience?
My analysis of W2DU's designs begins with slide 55 of this pdf.

Note that many (most?) things sold as a W2DU balun are either his
cheapest design which has not nearly enough beads -- poor choking, poor
power handling -- or uses a different mix. I don't recommend any of them.
