Being south of the border, you might not have these there. If you look at the lights arm attached to the Telco pole, you will see a small box. On that box is a little piece of wire sticking out of it. The box is only about 1-2 feet long and about a foot deep. I just happen to know what it is, but I wonder how many others do.



Hint: It has to do with telecommunications.
Answer down below.

Answer: It is a telephone repeater box. It picks up the signal from a cell phone, sends it over the telphone wired system to the nearest cell tower, which then sends it from cell tower to cell tower. It gets it's power from the electric eyes for each street light.


Thanks Harold!.

Harold,
I'm thinking one of two things regarding them pics.
Going by the top picture, your vehicle either has a sun-roof or you've managed to roll it onto it's side.

I thought it was some sort of wireless internet service like Ricochet or Wi-Fi. To small to be related to sell phone. It could also be the thing that reads wireless meters.

I've seen 'em in SoCal and always wondered what they were for.

I have spotted these on streetlights in Providence, RI. Since I frequently see them in bad areas and intersections, I assumed they were some kind of covert wireless camera system. But then I guessed they might have been a repeater system for the police/fire/emergency radio system.

So what do they do exactly?

You can always tell the frequency with the length of the antenna.
Figure in the Center loading coil and you're made.
But the question is, is it a half-wave, is it a 1/4 wave?.
Could it even be a 5/8 wave?.
So many questions!.
