  • Patent number: 8581797
    Abstract: A portable whip antenna (100) is used to form a parallel wire transmission line (304) and support for a dipole antenna system (900). The portable whip antenna is formed of an elongated monopole radiating element (306) extending from a feed point (114, 202) comprising an RF connector, which can be connected directly to a portable radio transceiver (200). A first flexible conductor extends parallel to and spaced apart from the elongated monopole radiating element of the whip antenna to form the parallel wire transmission line. A first dipole element (512) is formed from a portion of the first flexible conductor extending from a link member in a first direction transverse to a length of the elongated monopole radiating element. A second dipole radiating element (516) is formed of an elongated length of a second flexible conductor (522) extending in a second direction transverse to the elongated monopole radiating element.
