LIGHT POLE DEVICE

Information

I found this back in high school, I don't know where I dug up these pictures. The device has weather proof casing and an ~800MHz (approximate) band antenna under it. I've heard plenty of wild ideas about what this does, however nobody can come up with an absolute answer. I have seen devices such as this on many light poles before, this one was the only one that really caught my attention because of its size and disputed function.
