Hi, Brad.
My previous home was adjacent to a primary power distribution line
with three high voltage three phase lines, plus a residential
distribution line. Sometimes noise was fierce. I made a folded dipole
antenna out of 300 ohm TV twin lead, cut for the 75 meter ham band.
When first hooked to a receiver, I thought the receiver had died, but
eventually found a signal and it was working fine. Just no more noise
from the power lines.

If you can find a length of twin lead, try a folded dipole. I
currently use a horizontal loop antenna and it, too, is very low noise
pickup.
