accordance with local regulatory requirements. For information on 
setting radio power levels, see Transmit power control in the 
MSM3xx/4xx Access Points Management and Configuration Guide.

DESCRIPTION
The HP J9659A is an indoor ceiling grid-mounted omnidirectional 
array especially designed for use with dual-radio 802.11n access 
points. Six independent vertically polarized radiators provide null-free 
omnidirectional coverage for meeting rooms, offices, departmental 
areas, or other enclosed spaces.
ANTENNA LOCATION
For best results, mount the HP J9659A at ceiling level near the center 
of the coverage area. A line-of-sight path between the antenna and 
active floor locations works best. Avoid mounting next to a column or 
vertical support that could create a shadow zone and reduce coverage 
to a portion of the room.
