As already mentioned several times, objects with circular cross-sections can be
approximated with multiple planar rectangles without a big influence on the accuracy of the
results.
For the mast, this approximation is only used for the determination of the transmissions / penetrations (for example, for the determination of the shielding of the mast. For the reflections at the mast, the ideal circular cross-section is used to obtain high accuracy in the results.
At least 6 (better 10) planar rectangles should be used to approximate the cylinder
accurately.Figure 1. Modeling of a circular cylinder with multiple planar rectangles.
Parameters for the cylinder are:
height of cylinder
diameter of cylinder
number of corners (for polygon approximating the cross section)
location of ground plane center
The bottom and ceiling of the cylinder are not modeled because their influence can be neglected.
