1:1 Ruthroff Voltage Balun

    This balun transformer can be used for impedance matching with tuned dipole. Also it gives a balance in voltage levels in the arms of dipole. Ofcource it is a voltage balun and uses Ferrite rod from old MW radio's. The Copper wire used is 18 SWG wound trifilar on ferrite rod.

      A smart build simple construction with a central microprocession is the overall structure of SG 230 tuner. just sharing pictures i took before and after fault rectification.
