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 (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.
