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.

Connect Ground Wires to the Ground Buss Bar
Connect the ground wires on the cables to the ground buss bar using the hardware supplied with
the grounding kit. Connect the ground stud on the RFS to the ground buss bar. Use a ¼-inch
terminal lug to connect the ground wire to the ground stud on the RFS. Connect the ground buss
bar to earth ground. An example is shown in Figure 36.

Test the RFS & Cables
Test the RFS and the eight (8) cables using Appendix O, the RFS System Test Form. Record the
results in the form. For this test, use the cable connectors that will be attached to the BTS.
Include the jumpers and all surge protectors.
