A fundamental part of an irradiant element is the impedance matching.

In order to achieve the correct matching impedance between the irradiant and the feed line we need to build a balun.

Of course there are a lot of baluns diagrams out there in the internet. This is an easy one to build. You can use a ferrite rod from an old radio to build your own.

Expected: 1:1 balun diagram

Reality: 1:1 balun built by me
