Defective 4:1 Current (Guanella) Balun Design

This video is to make people aware of a 4:1 balun that keeps appearing, but this balun is not a balun at all! My first experience with this balun occurred many years ago when I was asked to look over a new publication on baluns. I was not the only person who pointed out flaws in balance in a few areas of the book. Unfortunately the book went to press without corrections. Unfortunately the book was widely accepted as a cookbook on balun design, even those the concepts of balance in the book were seriously flawed. Balance was not properly tested or discussed anywhere in the book, rather strange for a book largely about constructing baluns! A later experience occurred when a neighbor brought over his very expensive tuner because it was "biting him". His tuner had one of these baluns. I converted it to a regular 1:1 current balun and the problems went away. Most recently another friend brought one by. He was having some problems getting his antenna to work properly and wanted the balun checked out. It turned out to be one of these bad baluns! Over decades of time these baluns keep popping up!! Don't take my word for it, you can test this balun style at home using common readily available equipment. I hope others do just that.
