Mike,
Ken is correct. The dish units are UltraSonic locators using a parabolic
dish to detect ultrasonic audio freqs. You have to have already located the
electric pole or source for these to be useful. It's for pinpointing which
hardware is the RFI source, not for tracking RFI.

As I understand it, from seeing one being used by a rep from our local power
company, those are strictly for AF, not RF: i.e., for audible arcing of
connectors or connections on power lines.
For that purpose, they are very highly directional and accurate.
