Here's an example of where the word "balun" blows up our thinking about 
problem solving. The "balun" you're describing is a transformer, 
sometimes called a voltage balun. Other things commonly called a "balun" 
are a common mode choke, which should look like an open circuit at both 
DC and RF.

The word "balun" should be eliminated from our use. I know of at least 
ten very different things that are called a "balun."
