As you have a vector impedance meter have you measured the common mode

that are notorious for having poor common mode impedances.

Yes, the balun is a 4:1 voltage type. I have not measured the common
mode inductance yet. But in this case, the application is for a Carolina
Windom which requires common mode current to make part of the feedline
act as a radiator.

The feedline will be choked with a 1:1 current balun at the proper
distance. That is next on the list to be built.
