Visualize a 3D Fresnel zone in Google Earth

Here is an interesting tool to assist you with AREDN mesh network planning.
The Radio Fresnel website uses your data about the starting and end points of a possible RF link to generate a KML file which you can import into Google Earth.
The website has a sample KML file for you to download ans test. There is a short video which explains the data entry needed to create your own KML file.

Thanks to Bob KD2BKD for finding this site and bringing it to my attention.
