Don't do it!
Braid is a terrible choice for lightning or RF grounding, and its
much worse outdoors where corrosion will be a factor. You
won't find a single knowledgeable source who would ever
recommend braid for lightning protection outdoors.
Your best choice is solid copper wire. Tinned 2 AWG solid
copper is the "gold standard."
