My brother currently works for a security company has the contracts to replac all by itselfe some of those batteries that are backing up most of those cell phone towers

I was out exploring one of those crannies you can find in a city and ran into a cell phone antenna kinda nailed to a water tower. It was sitting there with its butt hanging out, gated on one side and totally open to about a half a million people on the other. (If they were willing to bushwhack a half a mile) It had an expensive looking mini container looking thing under it. Not even one no trespassing sign. Sort of random don't ya think?

It wouldn't surprise me.
You be surprised just how easy it is to get into the F.F.A.'s RADAR and NEXRAD Weather antenna systems that are normally on a high hill or mountain top.
But they do have "No Trespassing" Sign.
