Installing Antennas
Installation Considerations
Cisco recommends that you bulkhead mount the lightning arrestor so it can be installed as a wall-feed
through on the wall of the protected space.
The importance of obtaining a good ground and bonding connection cannot be overstressed. Consider
these points when grounding the lightning arrestor:
• Connect the lightning arrestor components directly to the grounding point.
• The contact points of the ground connection must be clean and free of dust and moisture.
• Tighten threaded contacts to the torque specified by the manufacturer.
Installation Notes
This lightning arrestor is designed to be installed between the antenna cable that is attached to an outdoor
antenna and the Cisco Aironet wireless device. You can install the lightning arrestor either indoors or
outdoors. It can be connected directly to a wireless device having an external N connector. It can also be
mounted inline or as a feed-through. Feed-through installations require 5/8 in. (16 mm) hole to
accommodate the lightning arrestor.
Note This lightning arrestor is part of a lightning arrestor kit. The kit contains a lightning arrestor and a
grounding lug.
Note When you install the lightning arrestor, follow the regulations or best practices applicable to lightning
protection installation in your local area.
Installing the Lightning Arrestor Outdoors
If you install the lightning arrestor outdoors, use the supplied ground lug and a heavy wire (#6 solid
copper) to connect it to a good earth ground, such as a ground rod. The connection should be as short as
possible.
