[RE-wrenches] DC lightning arrestors

[Darryl Thayer]

This last week I spoke with a cell phone tower installer.  He said, Nothing beats the ground! he said the most important thing is the tower grounding, The idea of 25 Ohms to Ground is way to high.  Ground rods are useless, and lightning arresters do no good without a good ground, in fact people who worry about the lightning arrestor putting power back into there system have something to worry about if the ground is not good. 
 
So that is what he said and was very adimit about it.

Is the best one can do as far as high DC array voltage the Delta LA602?
 
Didn’t they used to have a high voltage version of the LA302DC?
 
Thanks,
marco
