Simple balun
50ohm to 200ohm
Vari balun Balun 1:1 - 1:4 - 1:9

Simple balun- With these three wires I made 18 windings around the ferrite rod
50ohm to 200ohm- Balanced and unbalanced systems can produce common mode currents that cause equalizing currents at the interface of both systems. And exactly at this interface baluns are switched
Vari balun Balun 1:1 - 1:4 - 1:9- Baluns BALanced to UNbalanced are still a mystery for hams; the only way to understand this is to learn what it is and how to use it
