[TowerTalk] There's 'ground', and then there's 'ground'

Keith,

The general rule-of-thumb for ground rod spacing is simple and effective.
Space the rods twice the length of each rod and tie them together with
copper strapping, or heavy copper wire using 'one-shots'...  For example,
space 4 foot rods 8 feet apart, and 8 foot rods 16 feet apart.   This
spacing is suggested due to the effective circular field of each individual
ground rod and not to have any interaction between ground rods.  Polyphaser
makes a great ground rod bracket for copper strapping.  Erico makes
'one-shots' to weld heavy copper wire to ground rods.
