4.tuning is best accomplished by using an antenna analyzer attached to the far end of the coaxial cable that will be used with the antenna. once the initial resonant frequency is established, the antenna may be tuned just like a dipole. shortening the far end by 1” will raise the resonant frequency approximately 75 khz. if too much wire is removed, the included tuning stub may be attached to the 10-32 stud at the matchbox end and trimmed to establish resonance to the desired frequency (fig.2). fine tuning may be accomplished by changing the orientation of the stub with regard to the main radiator (i.e. rotating the stub and retightening the hardware. tighten the #10 hardware just enough to compress the lockwasher

4.調制最好被完成通過使用天線分析儀附有將使用與天線的遠端同轴电缆。 一旦最初的谐振频率建立，天線也許調整像偶極。 縮短遠端由1」將提高谐振频率大约75 khz。 如果取消許多根導線，包括的調整的殘餘部分也許连接10-32螺柱在火柴盒末端和被整理建立共鳴到期望頻率(fig.2)。 優化也許通过改變殘餘部分的取向完成關於主要幅射器(即轉動殘餘部分和重新拉緊硬件。 剛够拉緊#10硬件壓縮鎖緊墊片

非常感谢vr2vly！
大意看懂了。

可用一台天线分析仪接到天线所用同轴电缆的远端来获得最佳调谐效果。初始谐振频率确定后，天线即可按偶极方式调谐。远端每缩短1英寸，谐振频率即会提高大约75khz。若去除导线过多，则可将所附调谐抽头接至匹配盒端的10－32抽头，修剪后在所需频率达到谐振（图2）。若要微调，可改变抽头相对主振子的方位（即转动抽头并重新紧固硬件）。紧固10号硬件，使其刚好能够紧贴垫圈。
