> Take a length of the copper pipe (say 6" long) or tube with an ID about
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).
