Your first impression of the yagi antenna is that it's very much like a fish bone. The more antennas you have, the wider the coverage, the higher the speed. Right? Although many articles on the Internet have denied this claim, it is not groundless to delve into it, because to some extent, the number of antennas does have a lot to do with the transmission rate! Antenna can be said to be a lifetime of two, two three, three things... , the speed has also developed from the original dozens of megabytes to the current thousands of megabytes, but the first thing to be told is that the antenna increase is not simply 1+1.

The fishbone line is the yagi antenna, which has good directivity and higher gain than the dipole antenna. It is especially effective for direction-finding and long-distance communication. With elevation and azimuth rotation controls, it is possible to communicate with radio stations in all directions, including space vehicles, at will, advantages not available from vertical antennas.

大家对八木天线的第一印象就是很像一根鱼骨，天线根数越多覆盖越广，速率越高？虽然网上有众多文章否定过此说法，但仔细深究也并非空穴来风，因为在一定程度上，天线多少确实跟传输速率有着千丝万缕的关系！天线可谓是一生二，二生三，三生万物……，速率也从原始几十兆发展到现在的上千兆，但首先需要告知的是，天线的增加绝不是简单的1+1。

鱼骨线就是八木天线，它有很好的方向性，较偶极天线有高的增益。用它来测向、远距离通信效果特别好。如果再配上仰角和方位旋转控制装置，更可以随心所欲与包括空间飞行器在内的各个方向上的电台联络，这些优点从直立天线上是得不到的。
