Flush Mount Cell Site on PG&E Transmission Pole - San Jose, CA Airport2281 viewsThe interesting point about the cell antennas mounted to PG&E's transmission pole (seen in the right side of the photo) is that the antennas are not out on arms. Usually power companies require carriers to mount antennas on arms to insure adequate climbing space under NESC/CPUC GO95.

Sprint Conducts a Drive Test415 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.

Sprint Conducts a Drive Test397 viewsThe tech mounts the omnidirectional antenna to the telescoping mast. Once the antenna is mounted, he'll connect the coax that runs back to the portable PCS transmitter sitting inside the van. Then the tech will elevate the antenna to the desired height, and set the proper output power of the transmitter. With all this done, another tech will drive the streets in the area recording signal strength, latitude, and longitude for later mapping.

Penthouse external mounted site395 viewsThis is a plain, externally mounted cell site on a commercial office building. Note the GPS (timing) antenna well above the roof line, which might have been mounted at the roof level to minimize its visibility from ground level without impairing its function.

Building side mount omni site394 viewsNotice that the omnidirectional antennas are mounted on the side of the building near the corner. Even more interesting is that the GPS antenna (used for network timing) is mounted in such a way as to be shielded from about 120 degrees of sky (this site faces northwest).

RF on the Roof394 viewsThis commercial building in Tarzana, California shows how to poorly plan a roof by sticking almost anything (antenna wise) on the roof. A very poor (or good, depending on your view) example of how not to plan a rooftop.

Co-location cell site - sectorized and omnidirectional390 viewsA single monopole tower can support one or more sectorized carriers. The lower carrier does not use diversity reception (two receive antennas spaced so as to better receive lower power mobile handsets). The upper carrier does use diversity. Usually, in diversity configurations, the two receive antennas are on the outsides of the sector, and the transmit antenna is located inside, adjacent to one of the receive antennas.
