[QUOTE="Terryl, post: 1072427, member: 369937"] No the galvanizing will corrode with constant contact with the ground and it will not conduct as you expect. Do as I did, I used a 6 point ground system, (you can do 4) one ground rod as a center point, this is the main ground, then connect with 1/4 inch copper tubing buried 12 to 18 inches down out to 10 to 20 meters to the other ground rods.(in a square or circle as needed, with the main in the center) We used this all the time for VLF and LF frequency setups, also good for poor ground conductivity problems, the longer the ground radials the better the ground counter poise. On one setup we had to use 16 radials at 40 meters each for a good ground, as the soil was 90% sand. On one VLF setup we used a copper grid, 1 meter on center, in a field 16 acres square, that cost a bit in copper. Most AM radio stations use the same thing, they have a very large ground grid.
