We are planning on using the Plano Amateur Radio Klub (PARK) repeater locations as one of the sources for the data. Initial calculations so that the path should work just fine if moderate gain antenna are used at both locations.
I used the Splat! to look at the path profile. The link is here http://splat.ecok.edu/ecuindex.html
I know that my major issues will the trees in near my house. These are shown on the plot. Below is a path loss curve for this link.
