Is there please a limit on propagation range in Antenna Toolbox?

Hello everyone,

I would like to ask you for a help with Antenna Toolbox signal propagation simulation. I created an antenna using AntennaDesigner. I then placed two transmitters. One with power of 50W and the second one with power of 20000W. It seams that the circle for both antenna is the same. Is there please a limit on how far can I simulate the signal propagation?

Thank you very much

Just to add to my question. I did some calculations using google maps. It seems that the limit is 30 kilometers (radius of the green circle is 30 kilometers).

Is there a way how to turn it off?

Thank you

SOLVED IT!!!

The limit is 30 kilometers, but it can be extended using parameter "MaxRange" :

coverage(LH,"PropagationModel","longley-rice","MaxRange",500000,"Colors","red")
