The loss will be better than 90%. The metal car body "traps" the signal
and so very little of it escapes. Technical term is "the Faraday shield"
effect.
If nothing else, at least get a suction-cup mount and put the rubber
duckie outside.

piggyback another related query. Which is: can anyone tell me with any
authority, if using a full power HT inside a steel-bodied vehicle is
any kind of hazard to one's wellbeing ? Either HF or UHF.
Thanks, mark

Without an outside antenna, extremely poor. You will be lucky
to be able to talk a couple of blocks.

No problems with HF, but some say a potential hazard with UHF.
You would be far better off, in both cases, to use an external antenna.

I think the jury would still be out on that one, especially in the case
of UHF. I'd reccommend an externaly antenna, purely because you'll get
heaps better performance, especially on 27 MHz (where the car acts as a
Faraday shield). I've tried similar tricks on a train. UHF will work
inside reasonably well, but 27 MHz is totally useless, and the increase
in background noise and distant signals is very obvious when you step
onto the platform...
