Interesting pole Antennas: What are they for?

[Rob-F]

Question from an apparently out-of touch former electronics guy. Here is an antenna array mounted on a utility pole right across the street from our house. The Yagi antenna (gold colored) looks to be about UHF band, judging from its size. Then there are two quarter-wave center-loaded vertical dipoles in a ground plane configuration, inverted, with the ground plane disks mounted above the whips. They look to be about a foot long, so perhaps they operate around 250 to 300 MHz or so. And a box, evidently full of amplifiers and/or signal processors.

Interesting! But does anyone out there know what it's all for? TV? Big brother is watching? Police radio?

Perhaps it provides telemetry to monitor the power grid - just a wild guess. Or perhaps (another guess) it's an UHF repeater for some sort of public service band.
