Abstract (en)
A mast radiator (12) is affixed to a glass or other non conductive exterior panel (16) of a vehicle and is provided with a dipole element (18) and one or more parasitic elements to exchange signals, with gain, between the mast (12) and the antenna of a portable cellular telephone unit within the vehicle. In the preferred embodiment, a separate base unit (14) with parasitic elements is mounted on the same glass panel (16) on the opposite surface and opposite the base of the mast radiator (12). <IMAGE>
