HP 10.9/13.5 dBi Dual-Band Point-to-Point 3-Element MIMO Directional Antenna (J9170A) Guide
LIGHTNING ARRESTER
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
low-resistance 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 mastic 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.
Be sure to install the lightning arrester in an accessible location that
permits periodic inspection and replacement (as needed).
Provide drip loops in cables to prevent water from entering the
building. See Photo 3.
