SAFETY
The HP ProCurve J8999A and all associated equipment should be
installed in accordance with applicable local and national electrical
code guidelines to ensure safe operation.
Before connecting an external antenna to an HP ProCurve Wireless
Access Point, be sure that the access point radio power levels are
set in accordance with local regulatory requirements. For information
on setting radio power levels, see
Transmit power control
in the
MSM3xx/4xx Access Points Management and Conguration Guide
.
For antenna power settings by country/region, visit the online manuals
page for your access point at www.hp.com/go/procurve/manuals.
Please read all instructions carefully before attempting to
install and use this product.

APPLICATION
Designed for wireless LAN service, the HP ProCurve J8999A is a
directional patch array enclosed in a UV-stable weatherproof radome.
The focused radiation pattern may be used to extend point-to-point link
coverage or to provide targeted sector coverage in the 2.4 and
5 GHz bands.
ANTENNA LOCATION
The J8999A may be mounted in an interior or exterior location. A line-
of-sight signal path works best for point-to-point links. Although 5 GHz
signals penetrate cubical dividers and interior partitions with little attenua-
tion, reinforced block walls, banks of metal cabinets, glass walls, or steel
shelving may attenuate signals or cause multipath, a condition where
reected signals interfere with the primary signal. Because the antenna
beamwidth is narrow, it is important to aim the antenna accurately during
installation to provide optimum gain and best performance.
ASSEMBLY AND MOUNTING
The HP ProCurve J8999A is supplied with a universal articulating
mount that accepts mast diameters up to 2 inches (5.1 cm) or mounts
on a wall. This mount is especially designed to provide wide-range
articulation in both the azimuth and elevation planes.

GROUNDING
: System grounding and lightning protection are
essential, especially for exterior-mounted antennas exposed to the
elements. Never install an antenna where it may fall and contact
electrical lines.
