Too bad you couldn't use 300 ohm ladder line instead of coax. With the
addition of a antenna tuner and ladder line, you could eliminate the use
of the balun altogether and mathcing would not be a problem on any band
(well almost).

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
