I am uncertain. As stated before I have "heard" of soldiers communicating up to 10 miles. And as stated before the ground conditions and a few other things would also influence this. So, Idono!

500 watts into the ground? I bet that would wake up some nearby earthworms. I have read that the military has experimented with landmass antenna many miles long dumping a lot of power into the ground. The results I have not stumbled onto.
