My extensive modeling study shows that ground conductivity makes 
virtually no difference below about 30 degrees elevation, and the 
difference between Very Good soil and Very Poor soil is only 2 dB above 
60 degrees (Very Good is stronger). But this is soil, not what you can 
install in the form of wire underneath it. :)
