Soil resistivity is a measure of how much the soil resists or conducts electric current. It is a critical factor in design of systems that rely on passing current through the Earth's surface. It is a very important parameter for finding the best location of a transmitter working on low frequiencies (VLF, LF, MF and lower shortwave) as such radio stations usually use ground as counterpole. An understanding of the soil resistivity and how it varies with depth in the soil is necessary to desig… WebSoil Resistivity Table, Soil Resistivity Table Suppliers Directory - Find variety Soil Resistivity Table Suppliers, Manufacturers, Companies from around the World at center table ,dining …
