[Elecraft] Ground Rods

[VE3GNO Daniel]

Hi Gary,
 
Interesting discussion. Depends on what type of
soil, but as a general rule for lightning is much better with multiple rods
deep into dirt (9ft +) with spacing distance between rods equal or bigger than
the rod length. I've seen grounding installed close around a concrete structure cracking
the concrete base on a direct hit. Many hams are literally pushing a 3ft rod
into dirt, inefficient, my opinion is to prepare the grounding before and salt
it periodically. Here is a good document, is a must to be read for the ones
with lightning activity.

*Interesting discussion locally here in VK.

Is there any advantage in having the Copper ground rod surrounded by
concrete over having the rod driven 6 feet straight into the earth?

Hope this doesn't get too far off topic or develop into a prolonged
discussion but I realised I didn't know the answer if there is one.
