I saw this antenna matrix on the north coast of California this week on vacation (a couple miles north of Half Moon Bay). It's located about 1/4 mile from the beach on Highway 1. There is a powerline running past it, but it looks to just be getting much of its power from a trickle charge from a meter square solar panel. Do you have any ideas what it might be used for? I'm guessing that there are 7 horizontal dipoles in the disks, aimed in different directions, but for what? A multi-directional low power repeater? I couldn't easily get closer to the antenna pole (traffic is crazy on Highway 1 there). Maybe that would have provided more clues.
