    • A plate-shaped radiating element of a shape having at least three planes is formed by bending a metal plate having a substantially rectangular shape. A first slit is provided from a lower edge of the plate-shaped radiating element up to a portion in the vicinity of an upper edge of the plate-shaped radiating element while passing through a center point of the plate-shaped radiating element, and forms plate-shaped dipole elements on both sides thereof. A second slit is provided parallel to the upper edge of the plate-shaped radiating element and forms a folded element on an upper side thereof. Feeding points are provided on both sides of the first slit at the lower edge of the plate-shaped radiating element.
    • 通过弯曲具有大致矩形形状的金属板,形成具有至少三个平面的形状的板状辐射元件。 第一狭缝从板状辐射元件的下边缘提供到板状辐射元件的上边缘附近的一部分,同时穿过板状辐射元件的中心点,并形成 两侧板状偶极子元件。 第二狭缝平行于板状辐射元件的上边缘设置,并在其上侧形成折叠元件。 在板状辐射元件的下边缘处的第一狭缝的两侧设置有进给点。

    • A ground color main extruder 9 which supplies a ground color resin that is to cover a strand conductor 3 is disposed. Plural stripe sub extruders 21 and 31 which supply a colored resin in a strip-like manner in a longitudinal direction of the strand conductor 3 simultaneously with extrusion of the ground color resin are disposed. Insert molds 16 and 17 are multiply disposed. While alternatingly switching over the stripe sub extruders 21 and 31 each time when a colored resin to be supplied is changed, a colored resin of a predetermined color is supplied through a path which is disposed for each of the stripe sub extruders 21 and 31.
    • 设置提供覆盖股线导体3的地面色树脂的地面色粉主挤出机9。 设置与地面色树脂挤出同时在股线导体3的长度方向上以带状方式供给着色树脂的多条条子挤出机21和31。 插入模具16和17是多重布置的。 当每次当要供应的着色树脂改变时交替地切换条形子挤出机21和31,通过为每个条形子挤出机21和31设置的路径供应预定颜色的着色树脂。
