Figure 5-4 AW-100 to RU RF Cable Specification
Connect the external transmission lines from the diversity antenna systems to the RU
Antenna connections as shown in Figure 5-3. External connectors are “N-Type”.
Transmission line (or jumpers to transmission line) type and length will impact the overall link
budget calculations for the cell site. Be sure to include these losses in the RF system design
calculations for coverage.
5.4 Power Supply Wiring (DC Powered Models)
Applications that dictate only DC systems are to be used will require a separate DC
Distribution Unit (RPSU) which provides DC power distribution and over current
protection for connected equipment. The RPSU also provides voltage and current
measurement meters on the front panel. The RPSU will support the AW-100 and the
optional RU.
The RPSU must also be grounded in a similar manner as the other system components.
Connect the AW-100 main unit power interconnect cable between the main unit and the
RPSU Power Supply as shown in Figure 5-5. Use only the cable supplied with the RU
system for this purpose. Tighten connector captivating screws to prevent accidental
disconnection.
