When using Site Viewer I get the following error: Range is set to maximum propagation distance, which is Earth's radius, 6371km?
I can run the code you provided but do not encounter an error. The coverage map that results depends on whether the MATLAB release supports terrain. Before terrain support (R2017b and R2018a), the coverage map is large and idealized, reflecting only free-space path loss and the antenna pattern:
However, with terrain I see a more realistic looking coverage map, since the Longley-Rice model is used which includes loss due to terrain blockage and diffraction. For example, here is the coverage map running from R2019a:
Note that here the range of the coverage map is 30 km by default, which results in the smooth edge on the right-hand side. You can specify the "MaxRange" parameter to control the coverage map area. For example:
I recommend you upgrade to R2019a for terrain features with RF Propagation. In addition to default access to terrain data (Internet required) which I used to generate the coverage map above, you can also import DTED terrain using the new addCustomTerrain function. A couple of other new features you may be interested in are the ability to visualize the 3D radiation pattern on the map (see here) and ability to have multiple Site Viewer windows with programmatic control (see here).
