    摘要: A wide band biconical antenna with a helical feed system comprises a printed circuit board (PCB) that maintains a plurality of antenna elements having an entry conic and a termination conic arranged about a common axis. Each of the antenna elements receive a signal from a signal splitter via respective feed lines that each have the same physical length. In addition, the antenna system includes a matching system disposed within the ground plane formed by the entry conic of each of the antenna elements. The antenna elements are retained within retention sections that maintain helical support channels that allow the feed lines to be arranged in a helical manner about the antenna elements.

    摘要: A multiband antenna system includes a helical antenna having a first leg and a second leg wherein the first leg consists of a coaxial conductor. The multiband antenna also includes an antenna sub-system coupled to the helical antenna wherein the coaxial conductor feeds the antenna sub-system. A radome encloses components of the antenna system, and the radome may be covered by a radio-frequency transparent sock for concealment purposes.

    摘要: A biconical antenna includes an entry conic having an entry base opposite an entry vertex and a termination conic having a termination base opposite a termination vertex. The entry and termination conics share substantially the same axis and the entry vertex is adjacent the termination vertex. The transmission line is received by the entry conic and terminated in the termination conic. Together, the entry conic and the termination conic phase correct energy emanating from the transmission line. Another embodiment of the antenna comprises an entry conic having at least two sub-conics and a termination conic having at least two sub-conics. Each of the sub-conics having an integer multiple of a half-angle. The biconical antenna may also include a multi-conductor transmission line, wherein the biconical antennas are arranged in a colinear relationship. Each of the multi-conductors is coupled to at least one of the plurality of biconical antennas. The biconical antennas may also be constructed on a circuit board substrate.

    摘要: A spool for use in a trimmer head of a rotary trimmer having trimmer line is provided. The spool comprises at least three flanges (60, 61, 62) essentially parallel to each other. A passageway for the trimmer line is located between two of the flanges, the passageway (66) having opposed ends and extending from one side of the spool to an opposite side. The spool includes at least one inclining portion on one of the two flanges (60, 61, 62) about which the passageway (66) is located and at least one opening on the other of the two flanges (60, 61, 62) about which the passageway (66) is located. Each opening is in alignment and essentially contiguous with each inclining portion. The trimmer line may be wound onto the spool from the opposed ends of the passageway (66), between the two flanges (60, 61, 62) about which the passageway is located, up the at least one inclining portion, through the at least one opening, and into a space defined by the flange having the at least one opening and the third flange (62).
