2.4 GHz Sector Antennas

Sectoral Antennas: Compared to omnidirectional antennas, sectoral antennas have a smaller horizontal beamwidth, but not as small as directional antennas. A sectoral antenna can provide a wide area (for example 120°) with a high range. Sectoral antennas are often used for wide spreaded WiFi networks (for example at camp sites).

In principal: The higher gain of the antenna (declared in dBi), the higher the range of it.
