SAFETY
The HP ProCurve J8444A 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

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.
MOUNTING
The HP ProCurve J8444A is is suitable for use indoors or outside.
The antenna has been designed to mount to a mast at least 1-3/4 inches
(4.4 cm) but not larger than 2-1/8 inches (5.4 cm) in diameter. To install,
mount antenna clamp (17) to mast using U-bolt (4), lock washers (19),
and nuts (18). Slide antenna into clamp as shown and lock in position
using hex head bolt (14), lock washer (84), and nut (85). Secure cable to
mast using tape or cable tie.
ANTENNA LOCATION
The location of the HP ProCurve J8444A antenna is important.
Objects such as buildings, trees, power lines, towers, guy wires, glass
walls, and antennas and metallic objects, etc. will reduce efciency.
Best performance is achieved when antennas are mounted at the same
height and in a direct line of sight with no obstructions. If this is not
possible and reception is poor, it is a good idea to try a few different
mounting positions to optimize reception.
