Build Your Own 4:1 BALUN With Coax
Thank to Ralph Gable of "Electronics for the inquisitive experimenter" for this cheap and easy way to make a basic 4:1 BALUN. Ralph takes you step-by-step through the design and construction procedures. Each step is thoroughly explained and demonstrated.

Here are a few comments from Ralph: In this video I am going to show you how to build a 4:1 BALUN using nothing but a length of coaxial cable. I will work through the process of design and construction one step at a time with many pictures to show you how I did it. More than that! I am going to explain WHY it works. I sourced a number of books and the Internet looking for this answer and I was amazed at how little there was out there. Well, not so here. I give you the explanation plain and simple with simple math. ** IMPORTANT NOTE ** At 14:30 I state that 28.79 inches = 78.13 cm. R
