I would bond it to the tower on the way down, others claim that lightning current on the tower needs to stay on the tower and not get shunted to the ground wire...
(Jaime, my fingers may have finally learned how to automatically spell “lightening”...)

Just to the main ground at the base? What size wire did you use?

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.

Has worked well in our area. On May 9, 2017 3:25 PM, "Jason McKemie" <[email protected]> wrote: Wanted to get some opinions on grounding equipment at a tower site (on the tower). 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
