Not too compliant with the FCC OET Bulletin 65 Rules663 viewsThe FCC rules require that where visitors (and even trespassers) are expected, a wireless carrier must protect those members of the general population from RF exposure exceeding the uncontrolled standard. This site does not meet that requirement due to the antennas mounted on the exterior fence of this water tank site.

Das da ticket!643 viewsA close up of the AT&T Wireless DAS antennas. Note several things:
First, the RF warning sign is on the rear of the antenna, where is cannot be seen by someone approaching the antenna. This is not consistent with the FCC RF safety requirements.
Second, these are dual band antennas. In the far antenna, the cellular band antenna feed is on the right; the PCS band feed is on the left.

CellSign Updated557 viewsThis AT&T wireless site has been modified since the last time we photographed it. Search for "Pico" to find the original site configuration. Originally, this was a single band site; now this is a dual band site. The boxes adjacent to the amplifiers are called "tower mounted amplifiers" (TMAs).

Hot zone? What hot zone?722 viewsThis roof-top site (now removed) used cheezy plastic safety cones with pasted-on warning signs to alleged mark the edge of the general population/uncontrolled RF zone. Note the two cones at rear-right that have blown over. A very effective warning technique, eh?
