I'd like to clarify Sevik used transmission line mode, not transformer
mode coupling, in his single core 4:1 current balun. My contention is
it is impossible to build a 4:1 current balun on a single core unless
it is a primary-secondary isolation transformer, and an isolation
transformer would be a very limited performance balun compared to a
properly constructed transmission line balun.

Just so we know which Sevik design you are talking about, is it
Fig 9-8(B) of "Transmission Line Transformers"?
