In addition to grounding the equipment, BridgeWave strongly recommends, and local building
codes may require, that the power cable be protected from lightning strikes. If a copper Cat5 Ethernet
cable is used for Network Management access, it is also necessary to install surge suppressors at each
end of this cable. A surge suppressor must be placed within the radio enclosure (to protect the radio
electronics) and at the building exit/entrance (to protect the indoor equipment). BridgeWave
recommends the Dehn Patch DPA M CAT6 RJ45S 48.
2.7 Grounding & Lightning
Proper grounding of the outdoor equipment reduces
electromagnetic interference, provides lightning protection, and
protects against electrical discharge.
Using improper techniques in lightning prone geographic areas
may pose a danger to local personnel.
The source and connection points for the buildingtoearth ground
in the vicinity of the antenna location should be determined.
It is recommended to integrate the radio ground into the building ground utilizing the pole mount
hardware. For wall or ungrounded pole mounts connect a grounding wire to the grounding point on
the radio. Select the size of the ground wire based on the National Electrical Code.
In addition to grounding the equipment, BridgeWave strongly recommends, and local building
codes may require, that the DC electrical cable be protected from lightning strikes with a surge
