      • AB 240_250A Balun Kit

        If you want to make your own 4:1 current balun, this is the kit to use. The parts are high quality. It came with more than enough wire and insulation. The "K" ferrite core is excellent for this balun. I made an 80m OCF antenna and it tunes up good using the radio's internal tuner on bands, 80, 40, 20, 17, 12, 10, and 6. The results surprised me and the contacts are easy. This is a current balun so you can use this balun to match 1:4 or 4:1. I personally have 2 and I will buy more to make baluns for my friends. Buy the kit that includes the manual if you are new to winding baluns. Google "winding a 4:1 balun" for free information if you need assistance.

      • Great toroid, good kit, no instructions

        This kit includes an Amidon FT-240-K toroid and enough #14 polyamide magnet wire and PTFE to make a balun twice over. The tested permeability of this toroid was spot on its rated initial permeability of 290. This kit is geared specifically towards making the Jerry Sevick (W2FMI) designed HBM200 4:1 balun. This is from his book Transmission Line Transformers Handbook. What Mr. Sevick didn't know about baluns likely wasn't worth knowing, so you can be assured it's a good design. The only thing is, for a kit geared so specifically toward making one particular design, it would be beneficial if the kit actually came with the design. Not including the design seems to be aimed at selling a more expensive version of the kit that includes the entire handbook. It really wouldn't hurt them to ...
