FROM THE BALUN MANUFACTURER
After months of experimenting, I am offering up a different style of 9:1 unun. They are different in that they don't use the traditional toroidal core that you may be use to. The ones I'm offering up utilize ferrite beads that work very well. They are fashioned binocular style like you might find in amplifiers as coupling transformers. Mine use a lot less wire (28") than toroidal ones. The core material approximates type 43 which can cover a wide frequency range. I have found that the few turns of wire used only allows good performance in the upper HF bands, (40-6 meters). I've been able to get good readings, (SWR and Imp), with one antenna length, (33' to 66'), that will cover all upper bands, Antenna lengths can vary depending on how deployed, i.e. vertical, sloper, inverted "L" all work well but will need to be experimented with to achieve maximum performance. Power handling ability. (up to 100 watts). Great for QRP as well! comes with SO-239.
