Jeff,
You install ground rods until either your back hurts, your wallet hurts,
or both.
I have six 'strings' of four rods each for a total of 24 rods per
tower. Installed them 16 feet apart, in a one foot wide trench so I
would never trip over them. All are cadwelded with #4 stranded copper
and attached to tower legs with stainless steel shim stock and stainless
steel hardware.
I am comfortable with this installation.

I’m laying out the ground rod scheme for the towers.
As I look at Mot R56, it seems like about 45’ of rods gets you to the 5 ohm target based on one of
the graphics they provide That’s about 9 ground rods spread out in 3 legs each with 3 rods
separated by 16’ assuming 8’ rods and average soil.
While I realize more is better, how do you determine “enough” in the context of
ground rod count?
