 A bare wire will aid in lowering the ground resistance, like a vertical 
grounding rod, which is a good thing.

##  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.

Brian,


Yes, you are right all the shield of the feed-lines are connected (or should be 
connected) tween the tower and the shack ground. The risk of getting the 
shields 
fused (burned off) is reduced with a separate grounding wire between the tower 
and the shack. Large enough your shack might even survive a direct hit.


Again, the ground wire should be run close to the feed lines in order to 
minimize induced current from near strikes.

Most of us have that already in the form of out coax feedline's outer 
conductor. 

Typically this is grounded at the antenna and also in the shack. Am I right?
