Rquirements
Antennas & GPS Feeders
• Determine the length of the feeders for antennas
• On the same pole 2.5m ready made jumpers• 0-20 m ½”• 20-35 m ½” + 7/8” + ½”• 35 m ½” + 5/4” + ½”
• GPS feeder• 0-50 m RG-8• 50 m + ½”
Power
• Need 32A or 63A breaker in the rectifier• DCDU:
• load0-load4 RRUs (use load0,1,2)• load5-load8 BBU (use load5)
– Note: blue is -48V black, red or any given color is (+)
Fiber Optic Cable (CPRI)
• CPRI cable connections• CPRI0 to RRU1 (1st Sector)• CPRI1 to RRU2 (2nd Sector)• CPRI2 to RRU3 (3rd Sector)
• Longer naked end to the BBU• Shorter naked end to the RRU
Grounding
• Feeder every 20m on the tower (grounding kit)• GPS surge protector to the cabinet (6mm2 )• RRUs to the outside grounding bar (16mm2 )• RRU rack (if any) to the outside grounding bar
(16mm2 )*• BBU to the cabinet (6mm2)• DCDU to the cabinet (2 grounding cables, 6mm2)• 19” cabinet to the inside grounding bar (16mm2 )**if required
Labeling• Feeders:
Ports: A B C D
• Sector 1: R,RR,RRR,RRRR (tape rings)• Sector 2: Y,YY,YYY,YYYY (tape rings)• Sector 3: B,BB,BBB,BBBB (tape rings)• Yellow labels
• Sector’s CPRIs and Power:• Sector 1: Red (tape ring)• Sector 2: Yellow (tape ring)• Sector 3: Blue (tape ring)
• Printed labels on the power cable from the rectifier to the DCDU
• GPS Feeder:• Yellow label
VSWR
• Set frequency range 3.4 GHz to 3.6 GHz• VSWR has to be less than 1.5
