4:1 Current Balun using Ferrite rods
Guanella 4:1 Current Balun using Ferrite rods most articles on building the Guanella 4:1 Current balun use one or two toroids. For the range 1.8 MHz to 28 MHz
Zip Cord Transmission Lines and Baluns
A commercially available 4:1 voltage balun, was originally used for the transition between the 50 ohm coaxial cable and the balanced speaker wire transmission line
Calculating a choke balun
When the decision is made to put a balun type filter shoke choke balun, there is more to decide which coaxial cable to use; which diameter to give to the winding, and how many turns to put there
A Cost Effective Current-Mode 1:4 Balun
A cost effective current-mode 1:4 balun can be constructed from two lengths of coax, two ferrite rods
