Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 2d Part #40-00047-05 Rev F v1.0 (TTA) 65 October 23, 2003 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.

Ripwave Base Station I&C Guide Navini Networks, Inc. Chapter 2d 66 Part #40-00047-05 Rev F v1.0 (TTA) October 23, 2003 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. Figure 35: Completed Cable Installation at the Antenna 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.

Navini Networks, Inc. Ripwave Base Station I&C Guide Chapter 2d Part #40-00047-05 Rev F v1.0 (TTA) 67 October 23, 2003 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. Figure 36: RFS Grounding 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. Ground Buss BarGround WiresEarth Ground Ground Buss BarGround WiresEarth Ground
