[Icom] 706 in Suburban

Something to consider when talking about how to mount an antenna on a
vehicle:

The position of the antenna has a great influence on the RF lobe for the
transmitted energy. An antenna that is tied down close to the metal surface
of the vehicle will have a different impedance and thus different SWR plus
the radiation lobe will be very distorted and probably be directed into the
sky instead of horisontally. The possible range will then be reduced.
