The minimum bending radius of the main feeder should not be less than 20
times the length of the radius of the main feeder. For one-time bending, the
minimum bending radius is 90mm. The minimum bending radius of repeated
bends is 200mm.
●
The maximum spacing between the hangers is 1.65m.
2. Cabling procedure of the main feeder
1) Pre-install the three-feeder clips every 1.5 meters (or as per the actual condition
of the iron tower, but no more than 1.65 meters) along the iron tower or cabling
rack. Note that the spacing should be as even as possible and the direction of
installing them should be the same. When installing two rows of feeder clips
inside the same cabling ladder, the two rows should be parallel and arranged
neatly. Fig. 10.4-13 shows the outside view of a three-feeder clip.

2) Sort out the main feeders from the antenna to the equipment room inside.
3) Fix the main feeders from top to bottom and sort them out while attaching the
three-feeder clips. Fasten the feeder clips after smoothing the main feeders. Note
that you should keep the main feeders flat and straight rather than allowing any
bulge between two feeder clips or fixing the feeders at the two ends
simultaneously.
4) Fix the main feeders with three-feeder clips along the outdoor cabling ladders
prepared by the network operator for the main feeders to be routed along the
building top to the equipment room inside.
