12. The minimum bending radius of a feeder should be no less than 20 times the
feeder radius, and the bending radius of the main feeder should be more than
0.3m.
13. The cabling of the main feeders should be planned. When the cabinet front is
parallel to the direction in which a feeder enters a room or the cabinet back is
facing the direction in which a feeder enters a room, the main feeders within a
sector should be arranged as a row. The arrangement order of each row should
be consistent. When the cabinet front faces the direction in which a feeder enters
a room, one sector is arranged as a column and the arrangement order of each
column should be consistent.
14. The feeder connector should have no bare copper sheet. Two name labels should
be bound on both terminals of a feeder to ensure that feeders correspond to
antennas. Write corresponding lengths on a feeder name plate.
15. Avoid any dry joint in soldering GPS core wire.
16. GPS copper core and external outer layer cannot be short-circuited. The core pin
of a feeder connector should be parallel to the external end face of a GPS feeder
connector.
17. GPS feeder connectors should be tightened.
13.12 Installation and Check of Feeder Windows and Waterproof
Bend of the Main Feeder
Feeder windows and waterproof bend of the main feeder are installed as follows:
1. A feeder window is fixed on one indoor wall and the feeder hole bulging on the
feeder window faces outdoors.
2. The glue injection hole on the packing gland on the feeder sealing window
should be sealed upward and luffer boards should be installed on one indoor
walls.
3. When a feeder window is installed at the building top to lead a feeder into the
room, it should be well sealed.
4. When an outdoor feeder enters the equipment room, a waterproof bend must be
made at the outdoor feeder window. The lowest point of the waterproof bend is
required to be 10cm ~20cm lower than the lower edge of the feeder window.
