OTOH, for less money, you can buy a shirt-pocket handi with 2-band
transmit capability and AM receive capability on the aircraft band. I
built a 136-mhz moxon (from QST} out of hardware store aluminum rods,
and it works fabulously well, particularly when using the narrow rear
null to pinpoint a source. Even if you can just isolate the source to a
particular pole, the power company guys will be very grateful.
