I notice that the grounding conductor on utility poles (in the US) is
4 gauge or less. My understanding is that
this wire is used for lightning protection among other things. Is it
valid to say that 4 ga. is sufficient for the tower
to shack connection since it is sufficient for utility poles?

## The braid wont handle the current......so u still require 2 ga
bare, stranded copper wire between base of tower and shacks spg.
The 2 ga stranded, bare wire is buried in the dirt aprx 1-3 feet.
Then its in direct contact with the dirt. Even if the braid of coax
used, the coax would still have to be bonded to both top and bottom of
the tower. It still wouldn?t work, since the braid is covered
with insulation..and not in contact with the soil. Around here, the
electrical inspector will go crazy if you don?t install the bare,
stranded, min 2 ga copper wire between base of tower and shacks spg.
