Zodat de impedantie van open lijn dichter in de buurt van. 50 ohm van de coax wordt getransformeert. De SWR bij de balun kan ik niet nauwkeurig meten, is gewoon slecht op.

웹Balun 4:1 sur tore FT240-61. Quand j’ai décidé de transformer ma delta-loop 40m en OCF-Dipole 80m, une des raisons de ce choix était de pouvoir conserver le balun 4:1 que j’avais fait et donc pouvoir revenir en arrière facilement. Bien que le balun ne semblait pas être une source de problème et que j’ai pu faire quelques QSO DX ... 웹1일 전 · 4:1 impedance transformers (Baluns and Unun configurations) are available in kit form or assembled form in a weatherproof C urrent U nun and B alun E nclosure which we call CUBE Baluns™ and CUBE Ununs ™.
