Unmatch result in long distance
I build a model of an omnidirectional antenna at 915MHz in a 800m length and arched dome tunnel. The simulation results align with those in papers within the Line-of-Sight (LOS) region, but significant discrepancies arise over longer distances: my simulation results do not exhibit a periodic null points, it's too smooth.…

Load antenna pattern in Proman from WinPropCLI
Hi, I am trying to run a particular Proman project with different Tx antenna patterns using WinPropCLI. A simple code to run the project and save the results worked with: WinPropCLI.exe -F "C:\Users\Documents\indoor_winprop_test.net" -A --results-pro "C:\Users\Documents\Results\Run". But it did not work when I tried to…

How to use Type of prediction planes in WinProp API indoor
Dear, I want to predict a plane I defined in database. I searched the pdf of the API and had these values. However, I failed to find the corresponding variable for it. (xxxxxx = 0?) Meanwhile, I think in the indoor examples, in WinProp_prediction function, the area stored in WinPropArea is used, should it be replaced by…

How to use array tool in Aman to generate an antenna pattern with measurement gains of an element
Dear, I have measured gains of all my 16 single elements of my antenna array, where I'd like to use it as the pattern of a directional antenna in ProMan. Here's my thought. My data is in a .csv file, which is not quite able to be converted in to an .ffe file (if there's a way please ignite me), but I managed to convert it…
