Default Question on ground rods at base of tower


In the 2007 ARRL Handbook page 3.6, there is a discussion of building a
ground ring around the base of the tower, connected to three ground rods
each connected to each leg of the tower.

In the narrative it says "Space rods at least 6 feet apart" but then in
the caption for the accompanying drawing it says Locate ground rods on the
ring as close as possible to their respective tower legs".

On a Rohn 25G, the rods can't be "as close as possible" to their
respective tower legs and still be anywhere near 6 feet apart.

So, which is it ... close to their respective tower legs, or 6 feet apart?

What is the reason for the 6-foot separation, anyway? The rods all go
into the ground. Why would it make a difference if they're closer
together than 6 feet?
