The 1:1 shown is exactly the same as Balun Designs. Except for the housing.
Do you know that it's the same ferrite mix? That makes a huge
difference, and #31 the only one I've found that yields REPEATABLY good
high Rs values at HF. #43 and #52, which can provide high enough values,
but they are much higher Q than #31, so the wide mfg tolerances of all
ferrite cores causes every one to be different.
