Antenna Theory – UnUn Transformers for Impedance Matching

Baluns and UnUns come up frequently when discussing antennas of different types and matching feed point impedance so you don’t burn up the final stage transistors in your expensive radio. This video contains one of the best explanations I’ve seen so far of wave propagation in antennas, and how to build a transformer to convert […]

Studying for the General ham license, which is the next step up from the Technician’s license has led to some interesting (and entertaining) “ah-ha” moments for me regarding the design of radio antennas. Prior to dipping my toes into the ham test question pools, I’d always thought of antennas as passive equipment, responsible for receiving […]
