1:1 Choke. PART 1 Theory. [SUB ENG]

This first video explains, step by step, the theory that underlies the operation of devices for reducing common-mode currents (known as chokes or current Bal-Uns) that flow along a coaxial transmission line. Part 2 will explain how to size a choke in HF. Finally, Part 3 will describe how to measure its performance with a VNA.
