短波便携电台在使用杆状天线时,往往采用加感器同加顶辐射叶相配合的方法来调整不同工作波长上天线电流幅值沿线的分布,籍此提高天线的有效高度,改善电台在整个频段(特别是在频段低端)的发讯能力和收讯效果。关于加感加顶的理论分析和计算都很复杂,其结果往往不能切合通信实际,本文不作赘累的讨论,仅将我们试制的新加感器与正在使用的
Shortwave portable radio stations in the use of the rod antenna, the sensor is often used plus plus top radiation leaves matched with the method to adjust the different operating wavelengths on the antenna current amplitude along the distribution, thereby increasing the effective antenna height and improve the radio throughout the Frequency band (especially in the low end of the band) sending power and receiving effect. Theoretical analysis and calculation on the sense of plus top are very complicated, the results often can not meet the actual communication, this article does not tedious discussion, only the trial of our new sensor and are using
