# Of Windings ? - VK4CCV - 18-11-2024 Hi All, I am currently putting a High Power 4:1 Current Balun together using 2 stacked FT250-43 Cores. The design I am using is one I have seen on TRX Bench which has Left & Right Coils on the Core. He is using 12 turns on each side of the core. I am using insulated 16AWG Multi-core wire which is 3mm OD. My problem is, I am unable to wind 12 turns either side of the core. I can only get 9 Turns on before the ID of the core becomes full. I am now wondering how much efficiency I would loose with only 9 turns. Anyone ran into this before? Regards Pete DU7/VK4CCV |
