CB Radio

Can anyone advise what's involved in installing a negative ground CB radio
in a positive ground car. My understanding is that all the components have
to be isolated from any chassis ground of the car, and be grounded back to
the battery itself. This includes the antenna. Anyone done this?

And no, I'm not going to change the polarity of the car..........I'm too
much of a purist....
