AP-ANT-16 is a dual-band, 3-element omni-directional antenna designed for use in 802.11n MIMO applications. Housed in a compact, low-profile PVC/Acrylic radome, the antenna can be mounted to various drop ceiling grids using integrated spring clips. Each of the three MIMO antenna elements connects to the Aruba access point via a low-loss, plenum-rated coax pigtail. The radiation patterns are uniform and symmetrical, providing high-level signal density into defined coverage zones. This antenna significantly enhances the performance of 802.11n systems. The dual-band frequency coverage allows for a single type of antenna to be deployed with any MIMO radio in the 2.4-2.5 and 4.9-5.9 GHz bands. As a multi-antenna array, the AP-ANT-16 can be used with a single AP-124 to provide full dual-band 802.11a/b/g/n MIMO coverage, or the three elements can be used individually or in combination to provide diversity/non-diversity coverage with legacy 802.11a/b/g access points.
