• Snow and Ice — Falling snow, like rain, has no significant effect on the radio
signal. However, a build up of snow or ice on antennas may cause the link to fail.
In this case, the snow or ice has to be cleared from the antennas to restore
operation of the link.
Ethernet Cabling
When a suitable antenna location has been determined, you must plan a cable route
form the wireless bridge outdoors to the power injector module indoors. Consider
these points:
• The Ethernet cable length should never be longer than 100 m (328 ft)
• Determine a building entry point for the cable
• Determine if conduits, bracing, or other structures are required for safety or
protection of the cable
• For lightning protection at the power injector end of the cable, consider using a
lightning arrestor immediately before the cable enters the building
Grounding
It is important that the wireless bridge, cables, and any supporting structures are
properly grounded. The wireless bridge unit includes a grounding screw for
attaching a ground wire. Be sure that grounding is available and that it meets local
and national electrical codes.
