balun at resonance?
hi
i've build a 80 center fed dipole, cut for 80, to use multiband-- fed via coax. my goal is to use a balun. my recomendations so far have been for 1:1 /4:1 and 9:1, got nearly a equal tally of votes on each leaves me a bit confused however lets say i use a 9:1 for example on 80 my dipole is resonant, therefore should be around 72ohms. lets presume it is now w/a 9:1 attached what happens? is this my trade off, ie i become very ineff at resonance while gaining some better match at the non resonant points? thanks m |
