Balanced tuner or balun plus unbalanced tuner?
If balun, what kind? Was the balun seeing its
designed-for impedance?

What do you think would be the A/B results for
a resonant coax-fed dipole vs my notuner dipole?


Probably about the same. In theory you would have
slightly less loss than the coax, but at the lower
frequencies even the coax has very low loss.
So being the losses for both are very low, I don't think
you would be able to see much difference.
Or that's my gut hunch anyway..
Yours would probably be better than the coax if the
run was several hundred feet. At that distance, the
slight difference might begin to show up more.
Also if used at fairly high frequencies, you might
have an advantage. Depends on how good the coax
is how much it would be.
