Scott,

You should not have problems with noise getting into a coaxial cable unless
the cable is leaky.  What that means is if you have a break in the
connection and have connectors to mate the sections, the connectors may have
shielding problems that will let the RFI get into the transmission or
reception path.  Be careful when you make up your cables and ensure that
your coax shield is sound on each end and you should not have a problem.  On
the other hand, if your antenna is pretty close to other electrical lines
you could get noise to enter the path that way.

Alternators are inherently noisy.  You could consider shielding the wire and
grounding it on both sides to reduce noise.
