The antenna common mode impedance is 400-600 ohms. What you do with a
ground is not going to matter much, as long as the ground is less than 50
ohms resistance or so.
Unless you are on permafrost, dry sand, or some other terrible soil just a
couple ground rods are more than enough. A few short radials are just extra
insurance if the soil is questionable.
