Greg:
Don't use coax to connect your tuner to the antenna - the grounded
shield acts like a capacitor to ground and your tuner won't 'tuner'.
You need to make the wire from the lug to the whip as short as
possible - have you considered mounting the FC-40 outside the
vehicle?
You can use an 4:1 unun or an autotransformer in reverse- check out
K0BG's site at . I have used an
autotransformer on an powdered iron toroid core on my FC-40 to get
my 102" whip down to 60 meters, although I lost some S units on
recieve on higher bands.

Hey all,
I sold my truck with the 102 inch whip....I had the fc-40 about 3
inchis away from the inside lug of the ball mount so it was
perfect
for 10 gauge wire from the fc-40 lugs to the ant.
Now I cannot drill into my (new) Olds Bravada, so I need to figure
another way.
Can I cut off the end of a 15ft coax, wire it to the tuner and
connect the other end to a pl259 mount for the whip, off the
bumper
sor something?
Didn't think I could use a coax.
Also, what if I used a 4:1 balun in reverse to accept the wires
from
the tuner and adapt them to the coax to make the run over to the
whip?
Can a balun be used in reverse? Could use it in my shack to
attach
attick mounted slinky to the tuner.

Just a dumb general.
