  Take a 2 inch or larger copper pipe, 8 to 10 feet in length, and solder 
an end cap on one end. Solder a 90 degree elbow on the other end. Solder a 
fitting with a screw cap to the elbow. Drill 20-30 holes along the length 
of the pipe. Solder some type of attachment tab to the pipe elbow to allow 
connection of your ground cable. Fill this assembly with Epsom Salts. Bury 
in the ground horizontally as deep as you can and cover it back up with 
your available dirt. Remove the screw cap and add water till it won't take 
any more. Allow to sit for a few days before use. Top off the tube with 
Epsom Salts once in a while. I have used these on mountain top 
communication sites where there is almost no soil to drive a ground rod 
into. They work just fine..... WARNING!!!    May kill the grass in the 
immediate area of the burried rod.
