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 efficiency.
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.
NOTE: Mast top must be
lower than top of metal
Omni base.
