Chapter 4. Installing the Base Station ODU Radio and Antenna
D. Aperto recommends applying a silicone sealant or other weatherproofing to the
connections as desired.
Figure 4-7 RF Cable connects BSR to the Antenna
Step 6. Connect the BSR (ODU) to the BSU (IDU) - IF Cable
The coax cable connects the Base Station Radio to the Base Station IDU and provides
DC Power and IF Signalling. This cables runs from the outdoor radios to the indoor
Base Station Unit, so a suitable cable run and building entry point must be identified.
Maximum length depends on the BSR type and cable type used (Refer to
Table 4-2).
NOTE: For these outdoor-to-indoor connections, the order of the steps in the instal-
lation procedure will vary depending on a number of factors, including site particu-
lars and installers’ preferred practice. For example, in some cases it may be best to
run unterminated cable and then attach connectors; in others it may be more efficient
to attach one or both connectors to the cable before running it. Also, cable dressing
at various locations may be best performed at different points in the procedure.
Therefore, the procedures given for radio-to-BS connections should be taken as a list
of necessary steps and a suggested order, and modified as appropriate for your cir
-
cumstances.
