Does anyone have a good link or design for a 6:1 balun ?

This page shows one. Depending on your cores adjust the turns but not
the ratios.

I saw that one. It looks to be for low power. One thing I did not
understand is why they used 3 windings in parallel. Seems like just a
waste of wire.

I know I should be able to use larger wire and a larger core as long as
the number of turns are the same.



Perhaps it is the same logic as Litz wire. I haven't done the
arithmetic, but if skin depth at the frequency of operation is
comparable with the radius of the wire, or less, then it might make
sense.
