"""An antenna model similar to a GSSI 400MHz antenna in free space
|
|
|
|
This example model demonstrates how to use one of the built-in antenna models.
|
|
|
|
The geometry is 3D and the domain filled with freespace (the default). The
|
|
antenna model method is imported from its toolbox and the objects that build the
|
|
antenna are iteratively added to the scene. The antenna can be rotated if
|
|
desired, by rotating the objects that it is built from before they are added to
|
|
the scene.
