Selecting ground points
Select ground points for the IF cable.
Ground the IF cable at the following positions:
1. (Optional) Middle of the cable on the tower if the cable section on the tower is longer than 60 m
2. About 1 m before the cable leaves the tower and runs toward the outdoor cable tray
If the IF cable is longer than 60 m, one more ground point is required for every extra 30 m.

Installing a ground clip
Use a box cutter to strip off a section of the cable sheath. Take care not to damage the shield layer.
Install and waterproof the ground clip. (See the appendix for the waterproofing method.)
Ensure that the angle between a PGND cable and a power cable is
15 degrees or less. If the power cable is routed vertically, route the
PGND cable from the top downwards. Do not route the ground
cable upwards.
