Have you looked at NFPA 780-2011, standard for the installation of lightning protection systems as mentioned in 250.106?
I recently read somewhere else that any conductive material in contact with or in the vicinity of a LPS has a negative effect on the designed efficiency of the LPS, but have not investigated further.

Bare #6 copper and a split bolt to the braided copper connecting air terminals? At both ends of the array? Or should we not bond these systems on the roof? Opinions on a 2009 Wrenches thread varied, but I've heard it from a few sources that these should be bonded directly. Wondering if there is a general consensus at this point? Or strong opinions one way or the other? Thanks for your thoughts.
