3.3.1 Cable Laying Requirements
General requirements:
Bending radius of antenna feeder cable: 7/8 in > 9.84 in (250 mm),
4/5 in > 14.96 in (380 mm)
Bending radius of jumper cable: 1/4 in > 1.38 in (35 mm)
，
1/2 in (super soft) > 1.97 in (50 mm), 1/2 in (ordinary) > 5 in (127 mm)
Bending radius of power cable and grounding cable: > triple the diameter of the cable
Bind the cables according to the type of cable; intertwining and crossing are forbidden.
An identification label should be attached after the cable has been laid.
Grounding cable laying requirements:
The grounding cable must connect to the grounding point.
