High Quality Content by WIKIPEDIA articles! A sector antenna is a kind of directional antenna with a sector-shaped radiation pattern. In mobile communications, these antennas are typically installed in base-station sites for point-to-multipoint connections used in mobile communications. In WiFi, it is used for limited-range distances, around 4 to 5 km in practical use. A typical sector antenna is depicted in the figure on the right.

High Quality Content by WIKIPEDIA articles! A sector antenna is a kind of directional antenna with a sector-shaped radiation pattern. In mobile communications, these antennas are typically installed in base-station sites for point-to-multipoint connections used in mobile communications. In WiFi, it is used for limited-range distances, around 4 to 5 km in practical use. A typical sector antenna is depicted in the figure on the right. At the bottom, there are RF connectors for coaxial cable (feedline), and adjustment mechanisms. For its outdoor placement, the main reflector screen is produced from aluminum, and all internal parts are housed into a fiberglass radome enclosure to keep its operation stable regardless of weather conditions (see detuning).
