For those of you working with wireless networks, be it WUG, Wisp or even two way radios, Radiomobile is an amazing free program to plot links with topographical data. It has a steep learning curve, but there are some good guides available to help you get started.

Tutorial
If you want to plot coverage maps and such, you will need compatible antenna profiles. Ubiquiti provides these files on their website.
If you need something more basic for a simple link plan, simply draw a line on Google Earth, save it, and then in the left hand pane, right click on the line and select "Show elevation profile"
Hope it helps
