The HP J9169A is a dual-band, narrow beamwidth directional sector antenna for use in 802.11n MIMO applications. Enclosed in a compact, low-profile radome, the antenna is mounted to a rugged, articulating
mount. The mount can be affixed to a mast or anchored to a wall. Each of the three MIMO antenna elements are connected to the access point via low-loss, plenum-rated coaxial pigtails. The radiation patterns are uniform and symmetrical, providing high-level signal density into defined coverage zones.
This antenna will greatly enhance the performance of 802.11n systems. The dual-band frequency coverage means that a single antenna can be deployed with any MIMO radio in the 2.4-2.5 GHz or 5.1-5.9 GHz bands.
