Dunno about you, Lancer, but the last thing I'd want is RF inside the
vehicle.. which is exactly what's happening if you're using the coax
braid as the counterpoise/image plane/groundplane...even partially.

I know this was addressed to Tnom, hope you don't mind my 2-cents
worth.

Very few mag mounts have an adequate "RF" ground, at least on 11
meters or lower. There isn't enough capacitive coupling to the
vehicle body. In some cases the length of the coax can matter, not
from a matching point of view, but as a counterpoise for the antenna.
I have seen mag mount installations where you could see the SWR change
just by moving the coax around.
