A portable antenna is provided for mounting on a motor vehicle's side window and enabling easy and rapid mounting and removal. The portable antenna includes an outer RF transfer member, a current-fed radiator connected to the outer RF transfer member, an inner RF transfer member, a field-cancelling member operative to cancel the electromagnetic field in the plane of the field-cancelling member, and a pair of generally parallel wire members pivotally connecting the outer transfer member to the inner transfer member and bridging the inner and outer transfer members so as to overlie the side window when the antenna is mounted thereon.
