Target is 5 ohms but it often takes two three or more rods to achieve 5
ohms unless in a salt marsh swamp. Fresh water swamp land doesn't do as
well. A 20 ohm ground is more typical.

To put Steve's (G3TXQ) figures on a ground rod alone into a perspective
hams can relate to, the target low impedance for 60 Hz AC ground rods in
North America is 5 ohms. A 28 ohm ground rod at RF is alomost six times
worse!
