TT:
I used the staggered method when laying out the holes on my SPG plate.
I also used the Wireman's feed-through bushings and large bushing nuts.
This combination provided the connection to the SPG with a large surface
area to reduce (hopefully) the contact's resistance at the plate as seen by
a lightning strike. IMHO, the normal bushing nuts provide minimal contact
area with the SPG.
Sorry, I don't have the proper web page URL, but i'ts easy enough to
find at the Wireman's site.
