True, one should find the troublesome structure *first* with a 
radio, but *then* use a ultrasonic detector to locate the piece(s) of 
hardware on that structure that are causing the problem.   

Mike, of RFI Services, told me he would never be without both a 
radio *and* the ultrasonic detector.

As far as tapping the poles...it works most of the time to locate loose
hardware/connections, but it's a practice that CAN be unexpectedly
lethal.
