For about a year now, authorities in Salt Lake City have been trying to solve the mystery of a series of solar-powered antennas that keep popping up in the foothills around the city.
The first devices were discovered around a year ago. There was just a couple of them, but since then about a dozen have been reportedly located and disabled. According to the city’s recreational trails manager, the devices consist of a locked battery box, a solar panel, and an antenna. No one knows who keeps planting them and for what purpose, so for now all anyone can do is speculate and attempt to dismantle them, because they are installed on public land without a permit.
