Objects with Circular Cross Sections (Cylinders)
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.

Figure 1. Modeling of a circular cylinder with multiple planar rectangles.
- 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.
