长线天线

hellocq 有个很好的讨论贴，我现在的楼顶平台大概有80多米，足以架设长线天线，就是有些担心对顶层邻居家电器的干扰，有待测试，这个天线架设方便，打算近期就架设起来。

CobWebb 天线

特点是小巧，对周围环境要求很小，14Mhz-29Mhz边长只有2.5米，各波段振子互相馈电，在高频段起到八木的效果，有7DBi的增益。

• CobWebb Introduction
  

天线的种类非常多，仅在业余频段，就不时看见有人谈论自己没听说过的天线类型。所以打算整理一个天线的FAQ，先从整理天线书籍FAQ开始吧。

遇到好书就记下来，待日后寻找购买或者查阅。

电波传播与军用天线

中国人民解放军 张家口通信学院

包罗所有军用天线 简明扼要 注重数值调整.架设。

喜欢这本书是因为自己喜欢收藏军用电台，许多军机配的天线，由于那个年代技术有限，效率并不高，不过还是需要去了解，这本书就很不错。
