2.4 GHz and 5 GHz Outdoor 3-Port MIMO Omnidirectional Antennas (J9719A and J9720A) Guide
SAFETY
The HP J9719A and J9720A and all associated equipment should be
installed in accordance with applicable local and national electrical code
guidelines to ensure safe operation.
Before connecting an outdoor antenna to an HP Wireless Access
Point, be sure that the access point radio power levels are set 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 Configuration Guide.
For mandatory antenna power settings by country/region,
look for Antenna Power-Level Setting Guide (for MSM products)
at www.hp.com/support/manuals (search by antenna part number).
Please read all instructions carefully before attempting to install
and use this product.
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.

dESCripTion
The HP J9719A and J9720A are single-band omnidirectional antennas
for use in 802.11n MIMO applications. Enclosed in a weatherproof,
rugged radome, these antennas include a mast mount for outdoor
deployment. Each of the three MIMO antenna elements are connected
to the access point via low loss, outdoor rated coaxial pigtails. The
radiation patterns are uniform and symmetrical, providing excellent
signal level into defined coverage areas.
These antennas will enhance the performance of 802.11n systems.

ligHTning ArrESTEr
This is an outdoor antenna, but it may also be used indoors. For best
results, mount the J9719A or J9720A in the center of the coverage area.
A line-of-sight path between the antenna and active area works best.
Avoid mounting next to a column or vertical support that could create a
shadow zone and reduce coverage.
ASSEmblY And mounTing
The kit allows mounting on a mast (1¼ - 2¼ inches). Assemble and
mount the antenna as follows.

WARNING: PROFESSIONAL INSTALLATION REQUIRED: Prior
to installing or using this device, consult with a professional installer
trained in RF installation and knowledgeable in local regulations
including building and wiring codes, safety, channel, power, indoor/
outdoor restrictions, and license requirements for the intended country.
It is the responsibility of the end user to ensure that installation and use
comply with local safety and radio regulations.
Warning: Surge protection and grounding: When connecting an
outdoor antenna, make sure that proper lightning surge protection and
grounding precautions are taken in accordance with local electrical
codes. Failure to do so may result in personal injury, fire, equipment
damage, or a voided warranty. The HP hardware warranty does not
cover damage caused by static discharge or lightning strike.
For outdoor applications, it is strongly recommended that you install
a lightning arrester (HP J8996A or equivalent) for each port of the
antenna. Lightning arresters must be purchased separately.
For best results, install the lightning arrester in close proximity to a lowresistance ground at a point where the coaxial cable enters the building
or attaches to an AP. For exterior installations, use weatherproof coaxial
connectors with a suitable plastic or rubberized tape to prevent water
incursion. See Photo 2.
To connect the lightning arrester to the ground, use a very short and
direct run of # 10 solid copper wire, or equivalent. Ensure that the other
end of the grounding wire connects to a true earth ground according to
the NFPA 70 National Electrical Code and/or all pertinent local codes.
