If using braided cable, such as LMR400 size, Times Microwave does make a
grounding kit for RG8 braided size cable.  Not exactly cheap, but what is
your time worth?

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).
