The Yagi will have a very sharp null off the side.  If you have the direction reading dead on you can add or subtract 90 degrees to get the heading and in many cases plot a line from your tower in that direction on Google earth or other mapping program.  160 is more difficult to pinpoint it.

Yes, 160m is difficult. So now I am 90% done when they found that 160m 
source. For the other smaller issue I have the beam heading (from signal 
max & null) as well as AM radio detection of RFI at that place. I just 
need to use 6m radio tomorrow to narrow down the area. That general 
place matches the beam heading and the distance guesstimate (based on 
the frequency) using google earth (very useful tool!).

Yes and that is a big relief! Like you say, some power companies won't 
cooperate with this sort of things. That was my worst case scenario 
expectation and this is why I wrote the detailed letter making sure that 
they need to act on this. I don't take no for an answer :-)
