In the second article Keypounder has generously blessed us with, the issue of Baluns are covered. Baluns are most often (but not always) used as dipole centers to match BALanced antennas to UNbalanced feed line. (see why it’s called Balun?) While his article explains the nuts and bolts, in this abstract I’ll state that the effects are improved radiation efficiency (through impedance matching) and cleaning up noise that otherwise would be heard in the receiver coming from a variety of sources. Keypounder, as always, does an excellent job explaining the why and how through enabling the aspiring homebrewer. Take notes, knowledge can never be taken away.

Baluns and impedance transformers 101

By Keypounder

So, the NVIS article posted recently mentioned baluns, and in that article I mentioned that I homebrewed my own baluns and impedance transformers. So, what does a balun do, and why do I spend my time making…
