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 ProCurve
hardware warranty does not cover damage caused by static discharge
or lightning strike.
For external 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 connection near where the coaxial cable
enters the building or attaches to an AP. For exterior installations,
Qty
use weatherproof coax connectors with a suitable mastic or
rubberized tape to prevent water incursion. See Photo 1.

To connect the lightning arrester to the ground, use a very short and
direct run of #8 solid copper wire, or equivalent. Ensure that the other
1
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.

Lightning arresters require periodic inspection and replacement.
Provide drip loops in cables to prevent water from entering the
2
building or AP. See Photo 2.
