GROUNDING
System grounding and lightning protection are essential, especially for

antenna where it may fall and contact electrical lines (refer to the
National Electrical Code).

ProCurve 7 dBi Dual Band Directional antenna
J8999A
APPLICATION
Designed for wireless LAN service, the 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 band.
SAFETY
The ProCurve J8999A and all associated equipment should be installed
in accordance with applicable local and national electrical code guide-
lines to ensure safe operation.
Please read all instructions carefully before attempting to install
and use this product.
ANTENNA LOCATION
The J8999A may be mounted at interior or exterior locations. 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
attenuation, reinforced block walls, banks of metal cabinets, or steel
shelving may attenuate signals or cause multipath, a condition where
reflected signals interfere with the primary signal. Because antenna
beamwidth is narrow, it is important to aim the antenna accurately dur-
ing installation, in order to provide optimum gain and best performance.
MOUNTING
The J8999A is supplied with a universal articulating mount that accepts
mast diameters up to 2 inches (5.1cm) or mounts to any flat vertical
surface. This mount is especially designed to provide wide-range articu-
lation in both the azimuth and elevation planes.
