八木天线、定向天线、垂直天线、偶极天线有什么区别？

你说的这几个几个天线都不是一种分类方法。比如按方向性分，分为全向天线定向天线。八木天线是定向天线的一种。偶极天线是一种全向天线。等等。懒得打字了，等大佬来回答吧

@"[未知用户]"#p50660 请问天线手册在哪里看？

@"BI1XNA"#p50656 就是分类而已按形状和极化方向分

@"BH6BMJ"#p50992 形状：八木、偶极天线极化：定向、垂直天线

相同点：都是导电金属作为偶极子进行激励（all is dipole）不同点：不同点就是他们特点很不同 PS:建议看《天线手册》

@"BH6BMJ"#p50993 哇命令方块大佬在这啊，好厉害啊

@"BI1XNA"#p50656 八目天线具有方向性，所以属于定向天线；然后他的激励振子的馈电点在振子中间，一左一右两臂振子就形成了基本的天线类型“偶极天线”，而偶极天线之所以叫偶极，就是他有两个极（两个振子），典型代表就是水平DP、正V这些天线，那么如果我们把正V砍掉一截振子，然后把保留的这截天线竖起来，那么他就成了典型的。。。。GP天线（垂直天线）；所以。。。你说他们的区别吧，，，额。。。就是在形态上和馈电方式的区别。

What are the differences between a Yagi antenna, a directional antenna, a vertical antenna, and a dipole antenna?

What are the differences between a Yagi antenna, a directional antenna, a vertical antenna, and a dipole antenna?

BH6BMJ

BI1XNA It's just about classification, based on shape and polarization direction.

BI1XNA An octagonal antenna has directional properties, so it is a directional antenna. Its feeding point for the driving resonator is located in the middle of the resonator, and the two arms of the resonator form the basic antenna type "dipole antenna." The dipole antenna is called a dipole because it has two poles (two resonators). A typical example is the horizontal DP and positive V antennas. If we cut off one section of the positive V antenna and then stand up the remaining section, it becomes a typical... GP antenna (vertical antenna). So, if you ask about their differences, ... they are in terms of shape and feeding method.

The antennas you mentioned are not a classification method. For example, they can be divided into omnidirectional antennas and directional antennas. A Yagi antenna is a type of directional antenna. A dipole antenna is an omnidirectional antenna. And so on. I'm getting tired of typing, so I'll wait for someone more knowledgeable to answer.

BG5BJM Thank you.

I recommend consulting the antenna manual.

BD8CBP Thank you.

BH6BMJ Shape: Yagi antenna, dipole antenna Polarization: Direct, vertical antenna

BI1XNA

BH6BMJ Thank you.

BH6BMJ Wow, Command Block master is here! That's amazing.

Commonalities: All use conductive metals as dipoles for excitation.
The key difference: The key difference is that they have very different characteristics.

P.S.: I recommend reading "The Antenna Handbook."
