What is this metal panel under power lines?
I was hiking around the Berkshires in western Massachusetts yesterday, and came across this metal panel where some power lines were crossing a ridge:
The panel is a few meters wide, and appears to have no electrical connection to it. It cost someone some money to put up there, so there must be a real (profitable) purpose.
A flat metal panel like that would reflect microwaves. I notice it is facing slightly down. Is it possible that it is aligned just right to bounce a microwave signal from some tower I couldn't see down to something in the valley below? I think the physics would work, but I've never heard of such a thing, and never seen anything like this before.
