    One of the tricks my power company interference guy uses is to rotate the 
UHF yagi from horizontal
with the hi-wires to vertical and sweep the area. His comment to me was that 
about 90% of the noise
he finds is due to problems with the ground wire and the neutral hi-line. The 
last problem we found
 here was a guy wire back stay that was touching the neutral hi-line. I could 
hear it over a mile away
and it would come and go with the environment.
  One of the first things I always do now is to very carefully inspect the 
ground wiring with binoculars
 to see if there is any evidence of that wire touching any other metal objects 
on the pole that are not bonded.
    Ultrasonic is the way to go when you get close in for most cases except 
lightning arrestors,
 transformers, and underground wiring coming up inside the connection boxes.
