The AP-ANT-40 is a dual-band, four-element omnidirectional antenna for use in Wi-Fi MIMO applications. Housed in a compact, low-profile, and unobtrusive plastic enclosure, the antenna can be mounted on a variety of ceilings. Each of the four MIMO antenna elements is connected to the Aruba access point via a low-loss, plenum-rated coaxial pigtail. Radiation patterns are uniform and symmetrical, providing high signal density in defined coverage areas and optimal coverage conditions for MIMO performance.
