有时候端馈天线太长了，不方便架。底部加感的天线怎么做呢？在网上搜了几个，总觉得线圈和振子、地线的接法不够清楚，哪位大佬能给个更清楚的接线图？

@"BI1PMS"#p81704 你是说GP么？买个GP底座买个5.6拉杆

@"BG2EFX"#p81708 我不太清楚，可能是GP。想做那种类似汽车车身上装的，尺寸比较短，携带方便。一根拉杆+加感线圈。

@"BI1PMS"#p81723 如果固井架设你就按我说的买个底座 M10的加拉杆就行了用啥波段你就挑啥波段

@"BI1PMS"#p81723 我之前写了个小教程（ https://forum.hamcq.cn/d/6809/13 ）是讲DIY GP天线，里面给出了接法图示。过两天我会写一个加感线圈的DIY做法，含材料清单。配合上加感线圈后，整个天线从地面开始的顺序是：地钉+ 地网 -绝缘子- +延长杆- +加感线圈- +拉杆振子 >（部件前后的**+**符号表示螺头，**-**符号表示螺孔。地网是用接线环被其他组件压住的。)

@"BH5UNT"#p81735 太好了。谢谢！

How do I install a gain antenna?

BI1PMS

Sometimes, the coaxial cable is too long and difficult to mount. What's a good way to handle an antenna with a connector at the bottom?
I've searched online, but I still find the wiring diagrams for the coil, oscillator, and ground connections unclear. Could a senior member of the community provide a clearer diagram?

BG2EFX

BI1PMS Are you referring to a GP (presumably a brand name)? I want to buy a GP base and a 5.6 inch pull handle.

BI1PMS

BG2EFX I'm not sure, but it might be a GP (presumably referring to a GPS device). I was thinking of something similar to what you find on cars – compact and easy to carry. Something like a pull-out handle plus a sensor coil.

BI1PMS If you're setting up a well, just buy a base with an M10 thread and a corresponding threaded rod according to what I said. Choose the appropriate wave length based on your needs.

BI1PMS I had previously written a short tutorial ( https://forum.hamcq.cn/d/6809/13 ) includes instructions and diagrams for building a DIY GP antenna.

I will write a DIY guide with instructions and a materials list in a couple of days, including how to add a sense line coil.

In addition to the added loop, the antenna's sequence from the ground up is as follows:

Ground stake +
Ground network
- Insulator -
+Extension pole -
+ Add sensing coil -
+ Drawer-mounted spring

(Parts before and after)+The symbol represents a screw head.-The symbol represents a screw hole. The ground plane is formed by pressing the connecting ring against other components.

BH5UNT Great! Thank you!

Brother M has a video about going abroad, which explains everything clearly.

BI1PMS

BG8KUQ Okay, I'll look for it. Thank you.

You're connecting a resistor at the end of the cable...
