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.
For 4 MHz, I would use #61 material and
bifilar windings.
