To define a transmitter source in EM.Terrano, first you need to have at least one '''Base Point''' in your project workspace. Follow the procedure below: * Right-click on the '''Transmitters''' item of the navigation tree and select '''Insert New Transmitter Set...''' from the contextual menu. This opens of the Transmitter Set dialog.* Choose a name and color for your transmitter set. * From the dropdown list labeled '''Associated Base Set''', select the desired set.* In the "Custom Pattern [[Parameters]]", click the '''{{key|Import Pattern''' }} button to set the path for the radiation data file. This opens up the standard [[Windows]] Open dialog, with the default file type or extension set to "'''.RAD"'''. Browse your folders to find the right data file. * You can also rotate the imported pattern about the three principal axes. Enter the rotation angles other than the zero default values, if necessary.* Click the {{key|OK}} button of the dialog to close it.  A new transmitter set entry is added in the '''Transmitters''' section of the navigation tree.  A radiation pattern file usually contains the value of "Total Radiated Power" in its file header. This is used by default for power calculations in the SBR simulation. However, you can check the box labeled "'''Custom Power'''" and enter a value for the transmitter power in Watts.  [[EM.Cube]] can also rotate the imported radiation pattern arbitrarily. In this case, you need to specify the '''Rotation''' angles in degrees about the X-, Y- and Z-axes. Note that these rotations are performed sequentially and in order: first a rotation about the X-axis, then a rotation about the Y-axis, and finally a rotation about the Z-axis.
