I would think that by using both the center conductor AND the shield to
wire things up, RG8 coax cable would work as well or better than 1/2"
braided ground strap for the ground connection. Since RG8 coax has a
nominal OD of .4", and allowing for the outer insulation, the shield has
a circumference of about 1". This means that RG8 coax should be
equivalent to using 1" braided strap, and RG8 coax is certainly more
available to me than braided ground strap! On the down side, the
whole length of the conductor would not be in contact with the ground
because of the insulation, but would that make enough of a difference to
Does this make sense or am I missing something?
