Measuring Resistance
Verify that there is no more than 5 ohms of resistance between any two ground
points in the entire system. Also make sure that all ground points on a structure
are tied together. For example, if you use a ground rod and a cold-water pipe as
grounding points at different locations on the same structure, you must tie them
together.
Adding Surge Protection
If you’re installing a SkyPilot device in an area that’s subject to lightning storms,
SkyPilot recommends installing a surge protection device (SPD) at both ends of
the Ethernet cable—one at the SkyPilot device and one at the point of entry to a
building or enclosure.
SkyPilot offers SPDs with bracket and cabling designed for use with SkyPilot
equipment. For more information, visit SkyPilot customer support at
www.skypilot.com/support/ to view accessory guides for SkyPilot-branded surge
protection solution. (You may also purchase SPDs from third-party vendors.)
Grounding Checklist
When grounding a SkyPilot device, use the following checklist to confirm that
your installation is adequately protected from power surges and lightning.
 Connect a ground wire from the SkyPilot device to a ground system on the
building or tower.
 Use shielded CAT5 cabling and connect the drain wire of the shield to ground
at the SkyPilot device. (Leave the other end of the drain wire unconnected.)
 Use the proper size down lead to connect a SkyPilot device on a roof or tower
to the ground system of indoor equipment.
 Verify that all points of the ground system are tied together with less than 5
ohms resistance between any two points.
