Los Alamos, New Mexico157 viewsThis is a monopole owned by Alltel, and is located in Los Alamos, New Mexico. This tower is fairly close to the airport, so that's why you see an aircraft warning light on the top.

Light Standards with More584 viewsNear a hospital heliport, which explains the aircraft warning lights, the Verizon site (left) and the T-Mobile site (right) feature clamp-on radomes. The Verizon site also features a microwave antenna, which is unusual for light standard sites. Anaheim, California

Dish on a Light780 viewsLocated in a community park in Anaheim California, Verizon's foreground light standard site features a back-haul microwave antenna. The background light standard is T-Mobile's. Both lights have aircraft warning beacons due to their location adjacent to a hospital heliport (far background, also with panel antennas!).

Das da ticket!422 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.

T-Mobile's Take on a Cellular Pine735 viewsThis T-Mobile cell pine tree is located near the John Wayne Airport in Orange County. Of interest is the almost total camouflaging of the antennas by careful design/placement of the RF transparent "limbs". The limbs could have come down much further on the trunk.

Oh, yes, there's that aircraft warning beacon that helps the illusion.

Is that an AIRCRAFT warning light on the tree?865 viewsThis site is on USMC property in San Diego County. The red light on the trop of the cell pine tree warns off low flying helicopters. Notice how the bark cladding stops at the level of the lowest branches. Also notice how much reflective the trunk is without the cladding. The bark cladding should have been extended all the way up the tree trunk.
