Palms guarding cell site - circa 2001450 viewsHere's a photo of a PCS site I photographed sometime in 2001. Notice that its 'in the middle of nowhere.' Fast forward to the shot of the same site I took in October, 2004.
1. Antennas to be Hidden in Clock Tower450 viewsThree of four sides of the exsting clock tower had walls partially removed to permit the installation of RF-transparent fiberglass panels. As you'll see later, once the antennas are installed behind the panels, the panels are painted and textured to match the rest of the structure, thus hiding the antenna locations.
A Dam Tall Tower449 viewsThis tall tower, well, towers over Hoover Dam in Nevada and/or Arizona. I guess it depends in which state you live. This tower is on the Nevada side.
NextG Distributed Antenna System Node449 viewsNextG is a wireless carrier's carrier. They provide fiber links between the BTS and the antenna site using a technology referred to as Distributed Antenna System (DAS). This is a NextG DAS node located in Encinitas, California.

32. Looking down on the Activated Site448 viewsHere's the bird's-eye view looking down at the BTS equipment mounted on the far pad.
14. Installing the Telco Interface and Power Switching Cabinets447 viewsThe large cabinet on the right (with the open door) is to house the telco interface. A telco dataline is used to connect this cell site back to Verizon's mobile telephone switching office. The two smaller cabinets on the left, starting at the far left, are the power breaker panel, and the power generator transfer switch. The transfer switch senses loss of commercial power and automatically starts the generator (yet to be installed) and transfers power to the generator once stabilized. The reverse occurs when the commercial power is restored for a minimum period of time.
Close-up of Cell Antennas and GPS Antenna on Traffic Signal/Light Standard446 viewsThis is a close-up of the antennas mounted on the traffic signal. Note the two coax cables into the bottom of each panel antenna. One is for transmitting and the other is for receiving.
Spectrasite co-location site445 viewsThis Spectrasite cell/microwave site is located in Carson, California. The tower is registered to what is now Verizon Wireless. Note how the microwave antennas are identified by code to permit identification of specific microwave antennas from ground level. It's located in an "Enterprise" zone (sorry...inside joke).
Power transmission pole - Underground equipment shelter443 viewsThis cell site, on a power transmission pole, is connected to a controlled environment vault ("CEV"). The CEV is an underground room housing the equipment. The hatch for the CEV is the green box show below and to the left of the pole.
KMLT's Antenna Fence Under Construction443 viewsThe fence being constructed is to keep the hikers in the area away from the antenna site. At the time this photo was snapped KMLT was operating from its old (aux) transmitter site some miles away.
Light Standard Under Construction443 viewsThe double arms of this light standard, and the radome containing the antennas above the arms are yet to be placed.
Don't worry...the ladder will be removed before the concrete is poured.441 viewsWorkers preping the CEV for the concrete pour. The large holes are to connect to what will be intake and outflow air vents yet to be installed.
Rover's Roof440 viewsOn the roof of the drive test 'rover' is a GPS antenna (the square antenna in the center of the roof), plus two PCS omnidirectional antennas for signal measurement and communications purposes.
A Well-Done Grilled FM Station440 viewsKMLT's transmitter housing present appearance as of May, 2006 is virtually invisible. Easy to miss. Exactly what was intended! Outstanding work by Chris Hicks, KMLT's CE, the City of Thousand Oaks Planning department, and the Conejo Open Space Conservation Agency
Multi-carrier cell site and TVRO downlink439 viewsThe multiple carrier tower isn't connected with the TVRO satellite antennas in front, but it makes for a nice picture. This site is located in northern San Antonio, Texas at a very large church facility. An interesting note: The antenna structure registration number shown on the site is, per the FCC's database, cancelled. Interesting!
Close-up of GPS Antenna and LMU Antenna439 viewsCingular's GPS antenna (left) and the LMU antenna are mounted at about the 5 foot level adjacent to the sidewalk. It's amazing that they're still there. Hope no pedestrians walk into the bracket at night.
Co-location cell site438 viewsThe lower array was added after the tower was constructed. How do we know? Many of the cables for that array are mounted on the outside of the pole on the righthand side.
Sprint Conducts a Drive Test438 viewsWhen a wireless carrier selects a candidate cell site it will usually conduct a 'drive test' to determine actual coverage. The drive test consists of elevating an antenna to a predetermined height. Inside the truck is a portable PCS transmitter powering the antenna. In a separate vehicle (call it a 'rover') the carrier will drive the streets around the test site out to a predetermined distance from the site. The received signal level and GPS location information are stored in a portable computer inside the rover.

After the test is concluded, the received signal strength and location information are plotted on a street map. That map then serves to guide the RF engineer to select a final candidate site, and to design the antenna system to cover the desired area without causing unreasonable interference to other cell sites on the same network.

Attached to the left of the antenna (and blowing in the breeze) is a measuring tape used to determine the height of the antenna.
The Herd at the 2007 Rose Bowl438 viewsNextel, Sprint, and AT&T "cover" the 2007 Rose Bowl Game.
