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).

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.

The ProCurve J8999A and all associated equipment should be installed 
in accordance with applicable local and national electrical code guidelines 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-ofsight 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 during 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 articulation in both the azimuth and elevation planes.
 

ASSEMBLY
Install the articulating mount to the antenna back plane, as 
shown in Figure-1:
Hardware for MountingAntenna J8999A
1. Find the molded antenna mount (3) and four 8-32 nylon lock nuts (4). 
Use the nuts to attach the mount to the exposed studs on the back of 
the antenna.
2. Find the molded articulating arm (2). Also, find a 1/4"-20 x 1-1/4" 
machine screw (5), 1/4" lock washer (6), 1/4" flat washer (7), and 1/ 
4"-20 hex nut (8). Use hardware to secure the molded arm to the 
antenna mount as shown in Figure-1.
3. For installation on flat surfaces, find the molded wall/mast mount (1) 
and use it as a drill template to mark hole locations. Drill four 3/16" 
diameter pilot holes and install wall anchors (9). Install the mount 
using four 8-18 x 3/4" self-tapping screws (10).
4. For pole or mast installations, find two worm clamps (11) and install 
as shown on the molded wall-mast mount (1). Encircle pole with each 
band and tighten.
5. To attach the antenna assembly to the wall/mast mount, find a 1/4" x 
1-1/4" machine screw (5) and install a 1/4" lock washer (6) and a 1/ 
4"- flat washer (7) as shown. Use the screw to attach the free end of 
the articulating arm to the mount, securing in place with a 1/4"-20 
nut (8).
6. Loosen 1/4"pivot screws as needed to position antenna for desired 
azimuth and elevation steering. When antenna is in adjusted, tighten 
all hardware securely.
