2. Route the ground cable to the ground point.
When routing the ground cable, you must:
• Secure the ground cable at 5–foot (1.5–meter)
intervals.
• Keep the ground cable at least 3 feet (0.9 meters)
away from non–grounded metal objects.
• Make sure all bends in the cable have a sweeping
radius of more than 8 inches (20.3 centimeters).
3. Connect the hub lightning arrestor to the same ground
(reference) point as the ODU ground. See section 4.11.
4. Apply anti–oxidant (HNS 9008224–0002) to each ground
lug.
5. Apply 1/2–inch (13–millimeter) heat shrink tubing (HNS
9007488–0005) to each ground lug after the connection is
complete.
Important: You must slip the heat shrink onto the cable
before you make the connections.
