All,

I am trying to measure impedance through a balun, or more accurately a 1:1 in
line "transformer". For test purposes the transformer is two windings of 10
turns each on a toroid. The winding are tightly wound on opposite sides. The
material is #43, the toroid is 3/4 inch OD.

The windings should be bifilar, not wound separately.
