Hi John,
     I agree that ideally one has a perfectly resonant antenna system. There
have been times when I had antennas like that, and they worked well.
However, like you said, often one must work with what they have. SO, an
antenna tuner is a blessing if your radio just can't make friends with your
antenna.

God bless,
Mark

God Loves you!

with a balun you can connect ladder line to the radio. Not all external 
tuners can take it  either. If I need an external tuner, I'd rather adjust 
my antenna if at all possible so I don't need one. If that;s not possible, 
you gotta do what you gotta do but fact is, an antenna tuner  makes the 
radio happy, if the antenna has a high swr with no tuner, it will never play

near as well as one meant for the band. In different situations you just 
have no choice sometimes though.
