Installation Requirements
• 17 mm wrench
• 13 mm socket wrench or driver
• Clear line of sight between airFiber radios
• Clear view of the sky for proper GPS operation
• Mounting location with < 0.5° displacement due to twist and
sway under wind loading
• Mounting point:
• At least 1 meter below the highest point on the structure
• For tower installations, at least 3 meters below the top of the
tower
• Ground wires – min. 8 AWG (10 mm2) and max. length: 1 meter.
As a safety precaution, ground the airFiber radios to grounded
masts, poles, towers, or grounding bars.
WARNING: Failure to properly ground your airFiber
units will void your warranty.
• (Recommended) 2 Outdoor GigE PoE surge protectors
Note: For guidelines about grounding and lightning
protection, follow your local electrical regulatory codes.
• Outdoor, shielded Category 5e (or above) cabling and shielded
RJ-45 connectors should be used for all wired Ethernet
connections. Category 6 is required for installations with long
cable runs (up to 100 m).
We recommend that you protect your networks from harmful
outdoor environments and destructive ESD events with
industrial-grade, shielded Ethernet cable from Ubiquiti Networks .
