BALUNS: What they do and how they do it.
Thanks to Bill K5AXW for sharing this excellent article on baluns.
BALUNS: What they do and how they do it." is probably the best document one can read in order to begin to understand what a balun is supposed to do, and to learn which technologies actually do work.
In this article Roy coined the terms "Voltage Balun" and "Current Balun". More important, he also found out which types of baluns work as they are supposed to and which ones do not. As a result of Roy's work the 'current' balun began replacing the 'voltage' balun in Amateur Radio Antennas.
