    Running a copper strap from inside to outside of a residential structure 
isn't going to be pretty.  It isn't even done in commercial installations 
that I've seen.

     Let me suggest you run two beefy (#2) solid copper wires from your 
inside ground bar to the outside ground rods.  The copper strap provides a 
low-inductance conductor; the two parallel (but not too close) copper wires 
will do the same.  I would install the wires about a foot or more apart to 
minimize mutual coupling between them ( and the resultant increase in 
effective inductance.)

     You could use two separate, small PVC pipes to carry the two wires to 
the outside.  Easier and less unsightly than one large PVC pipe as you
