Chapter 2d

The RFS has ten cable connectors on the bottom of the unit. Eight are antenna connections, with
the connectors alternately numbered from right to left as shown in Figure 33. The two connectors
in the middle are for antenna calibration and data/DC power connections. Install surge protectors
on nine (9) of the RFS connectors – the eight antenna connectors and the calibration connector.
The surge protectors must be installed directly to the RFS to provide protection for the antenna
elements. Torque the surge protectors to 20-24 inch-pounds.

Install Cables Between the RFS & BTS

Connect all of the cables – the eight antenna cables, the calibration cable and the data/power
cable – to the surge protectors on the RFS. For ease of installation, install the cables from the
inside out. Ensure that the proper cable is connected to the proper antenna (Figure 35). Torque
the RF cable connectors to 20-24 inch-pounds.

Install Grounding Kit on Cables

Install grounding kit wire connections on the eight (8) RFS cables and the one (1) CAL cable per
the instruction sheet that comes with the grounding kit. Install the grounding wire in a position
on the cable so that it can be attached to the ground buss bar that is mounted close to the RFS.
More than one ground buss bar may be installed in the system, depending on the length of the
cable run. Reference the Regulatory Information in Chapter 1, Page 8.
