Connect the MRAU to SRAUs
CAUTION! To prevent interference, do not install an 850/1900 MRAU antenna near an 800/900 SRAU. The 850
MHz band must be 20 feet away from the 800/1900 SRAU’s passive antenna.
7 Use one of the following 6’ and 20’ CATV RG6 jumpers, available for purchase
from ADC, to connect an MRAU to SRAUs.
ADC Part Number Description Note
300469-0 6’ RG-6 Cable; F Male to F Male CATV cable that connects the MRAU to SRAUs. Two
cables required per SRAU.
300469-1 20’ RG-6 Cable; F Male to F Male CATV cable that connects the MRAU to SRAUs. Two
cables required per SRAU.
8 Test the cable termination for each CATV cable before installing it.
9 Connect
F connector CATV cables from the MRAU to an SRAU, in the order
given below. If the LEDs do not perform as described in this procedure, refer
to “SRAU LEDs” on page 8.
a Connect a CATV cabl
e from an MRAU FWD SECONDARY PORT (1, 2, or 3) F
connector to the SRAU SECONDARY FWD F connector.
b Confir
m that the SRAU SECONDARY FWD LED is yellow, which indicates a
correct physical connection.
c Co
nnect a CATV cable from an MRAU REV SECONDARY PORT (1, 2, or 3) F
connector to the SRAU SECONDARY REV F connector, matching the same
port number selected in Step 9a. That is, if in Step 9a you connected an F
connector to the MRAU FWD SECONDARY PORT 1, the paired CATV cable
must connect to the MRAU REV SECONDARY PORT 1.
If the connection is correct, the SRAU powers up
and the SRAU SECONDARY
FWD LED turns green.
