[Solved]What is this pair of metal... Things.. hanging on traffic light pole over an intersection?
(sh.itjust.works)
They were on all of them in the intersection, four sets
What's the big square antenna thing? Looks like a pretty beefy RF thingy. I've seen them on traffic lights and just by themselves. Are they detecting just the presence of big metal objects? Are they doing long range RFID?
