Yeah, never trust anything to be a ground except for a ground wire ran to your single point ground. I have even seen electrical conduit get hot enough to shock you due to poor connectors.

But based on experience, where we've lost gear from the steel bonding method, we went back and ran a bonding wire up and tied all of our gear to it and losses went down quite a lot. But I would also agree with Jaime. An air terminal at the top above everything is the best option for direct strikes. Utility power is the single worst problem at most of our sites. DC. DC. DC. Surge suppressors. Surge suppressors. Surge suppressors. Oh, and the single point bonding principle. On 5/9/2017 4:53 PM, Jason McKemie wrote: That's not really possible in this case. What do you think about bonding equipment to the tower vs a separate ground wire? I certainly don't want to make the equipment more of a target.

The tower and shelter are all properly grounded, it's a solid-steel leg tower. Right now I'm grounded via clamps to the tower. My question is would it be better/worse/the same to run a copper ground cable up to the equipment? It's going to end up being bonded to the same ground at the base, so I was thinking it wouldn't make a huge difference but wanted to see what others' experience was with this. TIA -Jason
