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.

ASSEMBLY
Install the articulating mount to the antenna back plane, as
shown in Figure-1:
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.
