Defining the Second Antenna Site and Antennas

Define the second cellular base station located on a lower hill. The antennas are placed 30 m above ground.

  1. Specify the transmitter type and settings using one of the following workflows:
    • On the Project menu, click Sites > Site: New.
    • On the Project toolbar, click the Set Site icon.
    The Transmitter Type dialog is displayed.


    Figure 1. The Transmitter Type dialog.
  2. Under Settings, click 3 Sector Site.
  3. Click OK to close the Transmitter Type dialog.
    In the 2D view, the mouse cursor is displayed as a circle to indicate that the Set site tool is enabled.
  4. Place the cellular base station with a left-mouse click on a lower hill closer to town in the model, at or near (X, Y) = (516000, 5402142) as indicated in Figure 2.
