There are several dozen of these that I've seen all over St. Louis. What are they/what do they do/how do they work?
The structures look quite a bit older than the solar panel/antenna that's mounted to them; I suspect that these power/transmit status information that was once gathered by hand.
I thought I smelled a faint odor of natural gas from these two that I photographed close-up; though this might be my imagination. Many thanks for your help.
