If you're really going to feed the antenna with coax, why do you need
a balun? Just run the coax straight to your tuner coax connection.


Sometimes an antenna needs matched to the coax line. An extreme example
is an OCF dipole, which can operate on several bands, but has an
impedence of several hundred ohms. the 4:1 or 6:1 balun will match that
with the 50 ohm coax.
