Oddly this is happening even on weaker noises that only move the
MFJ-856 meter to half scale or less.
I was fully expecting to find noise radiating from ground and guy
wires! But so far I always get more noise when pointing toward the
stuff on top of a pole than when holding the antenna nearly touching
a ground or guy wire. With some of the really strong noises I can't
determine this, and in those cases I probably do need more attenuation.
