A rooftop cell site is built when antenna and transmission equipment are installed on a building’s roof. The Subject Site, in this case, is located on top of a building or other support structure (such as a church steeple, billboard, flagpole, etc.). Its antennas and equipment are placed on the roof (or very top), typically with the antennas mounted near or on the parapet of the roof so that they can communicate in all directions. Most rooftop cell sites include three sets of antennas (aka “sectors”), which are pointed at 120 degree intervals from each other. There are typically between 2-4 antennas per sector. The equipment on the roof is connected to power and to backhaul (either via telephone service, microwave, or fiber optic cable) to the main telephone system.
