This balun is made using a ferrite ring from a TV deflection system. I think any radio amateur can easily find such a ring. I tested several manufacturing options, or rather, connection options for the balun transformer windings, for functionality. Screenshots from a vector analyzer screen for all winding connection options are in this video. I settled on the bifilar winding option, as it looked better than the others when tested with the NanoVNA antenna analyzer. I slightly compensated for the reactive component by connecting small capacitors in parallel. This setup resulted in quite decent parameters. This balun is fully functional and performs its balancing functions across the entire shortwave range, with an SWR not exceeding 1.2 on the 10m band.
