4.5.4 Installing RF Jumper
1. Connect the DIN connector to the antenna interface of the RRU, and use a torque wrench to fasten the
interface, as shown below:
2. Connect the other end of the RRU RF jumper to the feeder end of antenna.
3. Take waterproof measures for the connection port of the RRU RF jumper.
a. Wind three layers of waterproof tapes. Wind to the connector top from 50 mm at the bottom of the
RF jumper connector. First wind layer by layer from bottom up, then wind layer by layer from top
down, and finally wind layer by layer from bottom up. Cut off the tape after the three layers are
wound. After each layer is wound, use a hand to pinch the tape at the bottom to ensure waterproof
effect.
b. Wind PVC insulation tape by three layers. Wind to the connector top from 30 mm at the lower part
of waterproof tape. First wind layer by layer from bottom up, then wind layer by layer from top down,
and finally wind layer by layer from bottom up. Cut off the tape after the three layers are wound.
After each layer is wound, use a hand to pinch the tape at the bottom to ensure waterproof effect.
c. Bind a cable tie
at 3 mm‒5 mm from the end on the PVC insulation tape to prevent tape aging.
4. Check the dust cap of the antenna joint, and take waterproof measures for the dust cap by referring to
the previous step.
5. Lay cables according to the specifications, and bind and fix them with cable ties.
6. Stick a label to the installed cables.
