Install the RFS
Check all regulatory standards (refer to Chapter 1, Page 8 “Regulatory Information”) prior to installation. Now that the BTS is in place, the RFS is readied for installation. Follow the Panel or Omni Antenna information and procedures below. Reference the specifications in Appendix H.
Panel Antenna
The RFS Panel antenna is installed on a structure, such as a tower or a pole, which is defined in the site survey and design. Following are the steps to complete the installation of the panel antenna.
Verify RFS Operation
Verify proper operation of the RFS before installation. Test the transmit and receive path of each antenna in the RFS per Appendix S, and using the RFS System Test Form in Appendix O.
Set the Downtilt
Check the engineering study for the required downtilt of the antenna. The panel antenna has 6o of fixed electrical downtilt but it can be mechanically adjusted for an uptilt of 0 to 10o. As a result, the main lobe of the beam can be pointed between 4 degrees above and 6 degrees below the horizon.

Set the Azimuth
Position the RFS on the mounting pole or structure, ensuring that the antenna is pointing in the proper azimuth direction determined by the engineering study. For an omni, the first antenna element must face East (Figure 30).
