This absolutely makes sense. If it's low enough power, I see no reason
not to go this route, as it'll work even when PG&E doesn't.

I suspect it is indeed an omni, as all the ones that I've noticed have
been pointed directly downwards. The antenna for Fastrak and for
Caltrans' traffic/congestion monitoring look like UHF or SHF Yagi Uda
antennas pointing at people's dashes.
I see no reason this couldn't be that, but it seems like the antenna
design would have changed dramatically.

At least in the mission, their installation seems well timed with the
rollout of new parking meter heads.

They're not attached very securely. Most have been a bit of pipe
strapping (the kind with the screw) wrapped around a pole.

That said, these should not be touched or stolen.
