All you need are two pointed conductors. One for the ground side and one 
for the center of the coax.  They can be just that simple, or you can 
machine a fancy coax connector with adjustable points.    The conductors 
should be heavy enough to stand a pretty good jolt, but they can be 
sacrificial.  Just use your imagination.  Two points and two conductors.
