[Scan-DC] Question re: cell-like antennas on gas meters and such

[jay dehm]

I've seen around my neighborhood grey boxes on top of various
enclosers with cell-like looking antennas on them. I also saw a
stand-alone pole with a yellow box and at the top was a yagi pointed
off in some direction. As I don't have a frequency counter, I was
wondering if anyone could shed some light on the matter.

Thanks,

Jay
