A mobile device uses the user as the counterpoise.
A vehicle is not physically bonded to the earth - yet still works.
A Mag Mount antenna is not physically bonded to the vehicle body - hence
it uses a loop radio to antenna antenna to radio and it changes the way
the coax interacts with the antenna.
If the radio is bonded to the body and the antenna is bonded to the body
the body is capacitive. Turns the whole body into one big
counterpoise.

Maybe this is the reason why a 102 inch whip works better then a mag
mount antenna or one of those silly dual sticks on a truckers mirrors...

Not all know that:
""The necessity or utility of the earth connection has been sometimes
questioned, but in my opinion no practical system of wireless telegraphy
exists
where the instruments are not connected to earth."
