摘要： An adjustable mobile antenna comprising an upper metal mast and a lower metal mast, the upper mast being telescopically received in the lower mast and adjustably movable longitudinally therein to vary the length of the antenna and thereby effect tuning thereof, a clamping member for releasably locking the upper mast in a selected position relative to the lower mast, a dielectric rod extending upwardly from the upper end of the upper metal mast, and a loading coil helically wound on the dielectric rod with a lower end of the coil connected to the upper metal mast adjacent the upper end thereof, and a protective outer jacket covering the loading coil, the antenna being tunable by simply adjusting its length.
摘要翻译：一种可调节移动天线，包括上金属桅杆和下金属桅杆，所述上桅杆可伸缩地容纳在所述下桅杆中并且可纵向地在其中纵向移动，以改变所述天线的长度，从而实现所述天线的调谐，上桅杆相对于下桅杆的选定位置，从上金属桅杆的上端向上延伸的介质棒，以及螺旋缠绕在介电棒上的加载线圈，线圈的下端连接到上金属桅杆邻近其上端，以及覆盖加载线圈的保护外护套，天线可以通过简单地调整其长度来调节。

摘要： An adjustable mobile antenna comprising a dielectric rod several feet in length, a loading coil comprising a conductive wire helically wound in close fashion along an upper portion of the length of the dielectric rod, a protective outer insulator jacket covering the loading coil and a major portion of the dielectric rod, and a dielectric sleeve mounted on the outside of the protective jacket and slidable thereon along the length of the loading coil to effect "dielectric loading" of the loading coil to control the frequency of the antenna.
摘要翻译：一种可调节移动天线，包括长度为几英尺的介电棒，负载线圈包括沿着所述介电棒的长度的上部紧密缠绕的导线，覆盖所述负载线圈的保护性外绝缘套和主要部分介质棒，以及安装在保护套外侧的电介质套筒，沿着负载线圈的长度可滑动，以实现负载线圈的“介电负载”，从而控制天线的频率。
