Out here they mount boxes on the wooden utility poles
that have three antennas. These seem to be some kind

around and read each meter manually, they've replaced

Don't know what it is, but it may be totally unrelated to the streetlight.
Streetlights make a convenient way of obtaining power for devices.

The antenna seems to be a 800-1000 MHz 5dB mobile type.
Very sloppy install work.
I'd start looking for something around the 900 ISM band.

Mike,
That unit is a wireless utility meter transponder. Once an entire
neighborhood is outfitted with the new meters, they can be polled
automatically from a central location. It allows the utility to monitor
demand and power factor in real time as well as keeping tabs on total
consumption.

It's possible that the utility is experimenting with a system that was
previously used by another utility. I saw a rack of identical units- same
antenna as shown in Mike's pictures- at a PGE equipment yard in Santa
Maria. Depending upon the distribution voltages, a utility may choose a
There's another possibility: Since the electrical distribution is overhead,
it's possible that the unit was installed temporarily for investigation of
energy theft. If the utility suspects one of the customers served by that
pole to be stealing electricity, it is a simple matter to clamp a
