6月份有一天早上公园架台，通到河北宣化的几位老师，其中对BG3PUX老师的使用的，14兆单波段莫克森天线印象特别深刻，声音洪亮，59有加，我设备是IC718天线20端馈，第一次收到这么强信号的台。念念不忘必有回响，自己也想着做一副试试，简单记录一下过程。
1、Diagram: This Moxten antenna calculator can also calculate other segments; I previously made one for a U-shaped segment, which was quite fun.
2. Materials: Six types of network cables, PVC pipes. 4 strands in a single bundle.
Alternatively, other multi-strand soft copper wires, such as AWG 16 and AWG 18, can also be used.
3. Baron: You can buy a finished product, or you can make it yourself. (I made two, and my next experiment will be a double-wave inverted V.)
4、Assembly and Installation:
The antenna parameters are acceptable; I suspect the cable is too thin, and there was no consideration for a reduction factor. It could also be due to manual measurement errors, with a frequency offset of 0.15 MHz.
Since I didn't create an antenna frame, I temporarily attached four pieces of material to the corners of the antenna to the tree and the pole. This placement was ideal for securing it in place.
The antenna height is approximately two meters, and after testing with Linky, I found that the signal quality is noticeably better compared to the 20-meter end feed. FT8 communication with North America - 12.
5. In summary: It has a very strong directional signal, and it can receive strong signals from the back, but the response is weak, either receiving only 58 or 59, or no signal at all.
It's estimated that using a support structure of over 5 meters, combined with a rotating mechanism or manual rotation, would significantly improve the user experience.

Actually, building an antenna isn't that difficult; just get started, and you'll definitely find success.
I need to leave work on Friday, so I'll stop here first. Please let me know if you have any suggestions or improvements. I look forward to communicating with everyone over the weekend. 73!
