Over the years, I've seen documentation (ARRL antenna books, US military
publications) that adding chemicals around a ground rod decreases the RF ground
resistance.
Magnesium sulfate (Epsom salts) seems to be the preferred choice, with copper
sulfate and sodium chloride (common salt) being the second and third choice.
Does anyone have any info on any results of tests: resistance of ordinary
ground vs. resistance of ground with magnesium sulfate treatment?
