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 couple of
current transformers around the two hot wires going to that customer, and
feed the data into a transponder that's mounted out of reach.  If the
consumption data determined by the pole-mounted unit differs significantly
from that shown on the customer's meter, the utility has grounds to
prosecute.

Chuck,

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 PG&E equipment yard in Santa
Maria.  Depending upon the distribution voltages, a utility may choose a
radio based system in one area and a carrier-current based system in
another.  Remote meter reading systems are especially attractive in rural
areas, where a meter reader might have to travel for many miles to read just
one or two meters.

I have transponders made by Scientific-Atlanta and Motorola, but neither are
in the type of enclosure shown in the photos.  And that's part of the
problem- that enclosure is used by many unrelated companies for many
unrelated purposes.  A Wi-Fi network usually has two antennas cut for the
2.4 GHz band, which the antenna in the photos is not.  My conclusion is
based primarily on the unit's location, mounting method, and type of
antenna.

Perhaps Mike can contact his local utility to find out.  Or call the local
newspaper and complain anonymously that Big Brother is installing a citizen
tracking system.  That'll get some attention! <grin>

Eric,

Do you have the manufacturer? Based on the picture, this thing certainly 
doesn't look new. I have to assume that you recognize the particular 
device in use.
