>Everything I've read says you need to bond all grounding electrodes together. I think the electrical code requires this as well. If the tower took a direct strike, all the "earth" near the tower would be at an elevated potential with respect to "earth" further away (like the service entrance ground rod for the house). If I recall, the effect is called "step potential" and is due to the soil conductivity not being zero. That's not good as lightning currents will find whatever paths it can to try to equalize those voltage differences.

I disagree with all of that. See my other posts for an explanation.
