Multipole Antenna
When this option is selected, the following panel is shown:
In this panel, the user can select a multipole antenna file (.suj) from the local file system. This file contains the specification for a multipole antenna arrangement. The user can also specify a transformation to apply to the loaded multipole. The transformation consists on a displacement (given by a three coordinate vector) and a rotation (given by the X, Y and Z axes of the local coordinate system of the rotation). If the Relative to reference plane check box is selected, the entered displacement and rotation will be relative to the reference plane coordinate system. Pressing the Save button will add the multipole antenna.
