Hi Greg,
Nope! Now you know most everything about antennas:
http://service.gm.com/techlineinfo/radio.html Which is to keep the
transmitting antenna away from the car's computer.

And the coax and to power wires.
When the SWR is not 1:1, and the grounding is imperfect, some of the
RF will flow on the outside of the shield. The hot spots will be at
odd electrical quarterwaves of the operating frequency (234/Fmhz).
This is not to be confused with the false sense of security some
see by trimming the coax! (hahaha, don't fall for that). Inside
the coax, the electrical halfwave is 468/Fmhz*VF (velocity factor,
..66 for solid dielectric and .77 for foam dielectric). This is
frequency dependant, and any specific length is only for one
frequency. The coaxial electrical half wave will reflect the
exact impedance at the antenna feedpoint to the transmitter.
Any other location on the coax will be a different combination
of voltage and current lobes that will show the exact same SWR,
but since most meters read voltage, the apparent SWR will change
with the location of the meter in the coax.
If any of this doesn't make sense, post a reply and I'll try
to clear up any point that are unclear.
