Should I put a 1:1 balun on the setup or not?

Hi Mike,

RF in the cab will keep you awake during long night drives. Just sit
on the mike enough that if you start to nod off, it fires up the rig
and the seat of your pants both.

Seriously, asking this one question only opens Pandora's box to all
the ways RF leakage and common mode can stop you dead in the road
(blame modern automotive technology). Your mini SUV is the major
radiator, the "antenna" is merely a tuned radial. There are some
elements of a Faraday cage here, but there are also elements of where
the cage fails, so does your control of RF in the cab, under the hood,
in the glove box, what-have-you.
