[TowerTalk] Fair rite materials for choke baluns

[Steve Hunt]

What I do is connect the choke across the output of a tuner to generate 
a CM signal across the winding. Adjust the tuner for a good match to 50 
Ohms and drive it from a transmitter. That way you have a 
well-controlled experiment.

You can measure the CM voltage across the choke and the current through 
it, or calculate them knowing the power output from the Tx.
