NextG (Crown Castle) Dual DAS in Redondo Beach, CA114 viewsThis is an example of why the assertion that 'DAS and done' is not always true. This site was originally permitted as a single DAS site, but another carrier wanted to be at the same site, so a larger cabinet holding two DAS nodes was installed, as was a second antenna.

Das da ticket!426 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.

Awful AT&T Antennas496 viewsThis rather awful antenna site, from AT&T wireless, is located at 10239 1/2 Vassar in Canoga Park, California. The dual band antennas use tower mounted amplifiers to enhance weak signal reception.

Sprint's Dual Light Standard Site556 viewsHigh above the US101 (Ventura Freeway) in Thousand Oaks sit these dual light standards. Two light standards provide three sectors of diversity coverage in this very high (RF) traffic area. The equipment is located in an underground vault. Rasnow Peak can be seen in the distance.
