You must be pushing a lot of power, or your battery was ----. I have
left my CB on for like 3 days(with the truck parked the whole time)
and not had it run the battery down. They draw almost no juice on
receive. As a matter of fact most of the newer fuel injected cars
draw more than a CB.

In this day and age of multi GHz computers the 27 MHz that CB's operate
that is basically considered DC. An inline RF choke will adequately
block 27MHz radiating back through the power lead. Of greater concern is
blocking chassis noise from the radio. A fused lead to the battery or
the power block are equivalent. Any chassis ground is as effective as a
separate ground lead. Metal to metal anywhere on a jeep should be less
than an ohm. As far as metal mounting the chassis, that is the safest
bet. If the unit needs isolation from the chassis it will be done
internally. Grounding at the antenna is determined by the antenna. If it
requires then a fat pigtail as short as possible is recommended.
Non-grounded antenna are less effective since they do not use the body
of the vehicle as a ground plane. In the final analysis, most of this
does not matter if you tune the antenna for a low SWR.

And that's EXACTLY why one isolates the antenna and CB in a Jeep to
avoid ground loops. Jeeps are notorious for not having good grounds,
particularly back in the days when CBs were more common. It was very
difficult to get a good noise free signal in Wagoneers and Cherokees
leading to the development of isolated mountings to avoid ground loops.
Grounding the antenna to the body (as most installations do) is
surprisingly unsuccessful when the body grounds are rusted away.

It wasn't a CB. It was a combo police radio, scanner and control for the
