I need a sanity check. I fellow told me he was getting a balun to get a
better match between his receiver and antenna to get a better signal to
noise ratio. I told him he was wasting his time and money because a better
match increases transfer of both signal and noise. But since he already can
hear the signal he doesn't need any more. Now if he was to get a more
directional antenna he would get a reduction in noise from the undesired
direction.

I ran a test at my QTH with my horizontal dipole fed with
vertical ladder-line. I removed the balun-choke at the coax
to ladder-line junction. The noise level went up by almost
one S-unit. I suspect the culprit is localized vertically
polarized power line noise that has thwarted my every
attempt to use a vertical on 40m at my QTH.
