Balun 1:1 do W3DZZ
Poniżej zamieszczam model, którego ja używałem do symulacji W3DZZ. Dodałem do niego drut do symulacji wpływu prądu common mode. W zakładce "Symbols" można dowolnie zmieniać wszystkie istotne parametry włącznie z kątem pomiędzy ramionami (różne warianty zawieszenia V / invered V)
Z uwagi na długość niektórych linii model może się rozjechać - trzeba będzie to ewentualnie ręcznie poprawić po wklejeniu.
