the same or *slightly* larger than the diameter of the  coax with the 
jacket removed.  Split the copper tube or pipe  lengthwise (IOW saw it 
into two mating pieces).  Solder/Braze  the  ground wire *lengthwise* 
onto the outside of one  half.   Clamp it to the braid by wrapping the 
sections with the  rubber vapor wrap and tape which also water/moisture 
proofs the  connection.


        Soldered/brazed joints are  not appropriate for lightning systems. 
The only NEC approved grounding  connections are compression or exothermic (e.g. 
CadWeld).
