This model represents an update to the previous model of the GSSI 400MHz
antenna and was created and optimised by Stadler et al. (2022)
in: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9686638.
Can be used with 0.5mm, 1mm (default) or 2mm spatial resolution.
Can be used with 2mm spatial resolution.
The external dimensions of the antenna are 300x300x178mm.
One output point is defined between the arms of the receiver bowtie.
The bowties are aligned with the y axis so the output is the y component

How to use the package
======================
The antenna models can be accessed from within a block of Python code in an input file. The models are inserted at location x,y,z. The coordinates are relative to the geometric centre of the antenna in the x-y plane and the bottom of the antenna skid in the z direction. The models must be used with cubic spatial resolutions of either 0.5mm (GSSI 400MHz antenna only), 1mm (default), or 2mm by setting the keyword argument, e.g. ``resolution=0.002``.
