In this example, the propagation factor of a simple antenna is calculated and visualized.
Start newFASANT window
Select File and click on New
Click on Terrain→Import Terrain, and a new tab will appear.
Import Terrain Menu
In the Import Terrain tab click browse and select the desired file.
As the file is .asc it's necessary to have a projection file. If it doens't exist, clock OK in the pop-up window that will appear. Else, click on the Edit PRJ button next to browse.
Select the type Geological, factor of 1 degree and 45º of latitude. Then click OK.
Introduce the display options and click Save,
When the terrain appears, click Profiles→Extract topographic profiles→Profile between two points.
In the console, write the point "-3700 1600" and press enter, then do the same for the point "1100 -1600". This points can also be selected on the terrain.
Select Simulation cases→New case. Click New Simulation Case. Then choose a name and press OK.
Click Add profile and choose a name.
Add height points at 750 and 1000 meters and then change the refraction to match the image below. Then save the profile.
Switch to the Case Definition tab. In the Topographic Profile section, choose the profile and set the reference height to 550 m.
In the refraction section, select 6 km of range and the created refraction profile and press add.
Set the antenna parameters. In this case we will use the default values.
In the simulation parameters, set the range step size to 0.01 km, the height step size to 1m, the range limit to 5.5 km and the height limit to 600. Then save the simulation case.
Select Calculate→Execute on the menu bar. Select the case to process and press execute.
When the simulation finishes we can visualize the simulation results. Click on Results→Propagation Factor→Propagation Factor Spectrum.
Select the case and press add series.
Right click on any point at 250 m of height and select Profile at selected height.
In the chart window add a series at 275 m to compare both values.
