I wasn't talking about that particular balun just that particular method of construction. If a balun like that one were made resonant at, say 7 MHz, would it still be useful at 4 MHz? at 2 MHz? In other words, what is the shape of the choking curve below resonance for that particular method of construction? -- 73, Cecil, http://www.qsl.net/w5dxp |
