. No reverse folding is allowed.
In the case the antenna feeder system is installed on the tower, the grounding
cable of the grounding clip should be led downward along the tower body.
In the case the antenna feeder system is installed on the roof top, the grounding
cable of the grounding clip should be led close to the building lightning
protection grid.

1 ) First wrap the waterproof adhesive tapes and then wrap the PVC tapes.
2 ) To wrap the waterproof adhesive tapes, apply them layer by layer from bottom
to top first, then from top to bottom once again, and finally from bottom to top
thrice, that is, wrap three layers of them. During the process, make sure the
upper layer overlaps the lower layer by about half the width of the tapes.
