Soil dielectric constand and conductivity for East Texas
Do a web search for "OWL" (qualifying it with ground conductivity-related
terms to cut down the references to the bird and other contexts). I believe it stands for "open wire line", and the last I heard, was the standard way of measuring RF ground conductivity. It involves a buried open wire line, but that's about all I know about it. There's certainly nothing wrong with learning to measure ground characteristics as an educational process. No matter what seemingly useless learning exercise I undertake, I ultimately learn many other things from it. By all means, go for it. I'd love to see some results from one of the good field solving programs for stratified grounds, even something contrived, and even a simple vertical with buried or elevated ground system. What I'd like to know is whether there really is a single value you could assign to a single homogeneous ground and get the same results. I suspect not, but have no proof one way or the other.
