ground wire).

I'm surprised you've come to this conclusion, if you have the Polyphaser
book. Each ground rod serves to divide the incoming energy. My advice:

Don't let 'cost' enter into the 'need' function...

Try copper pipe. Start with an 8 foot length; drive it until you reach
rock (drop a large bolt in the end so it doesn't mash). Then cut off 
what sticks out of the ground and move on to the next one.
