All About Baluns (Ask Dave #73). Post 1772.

Sometime in your amateur/ham radio "career" you'll run into baluns and their intricate relationship with antenna performance.  A balun is a device to convert a balanced transmission line to an unbalanced transmission line and vice-versa.  Baluns are vital in coaxial cable fed transmission lines, especially where long wire and off-center dipoles are concerned.

In this video from David Casler (KE0OG), Dave answers questions about baluns, how there're made, the various ratios used (such as 1:1, 4:1, 9:1 and other values), and how baluns enhance antenna performance and ultimately protect your transceiver.  Dave's explanations are clear and easily understood.  This video would make an excellent presentation for a club meeting or an amateur radio licensing class.
