@"BH4FCY"#p100534 馈线接头，它为啥一定要这个角度呢？

@"BI1SFC"#p100547 感觉有可能哦，如果90度直插又太占空间，所以折衷一下斜插。 👍

@"freedom_liao"#p100561 就和各种连接器，接插件一样，接口，方式有很多种，在满足功能和性能前提下，具体用哪种接口和方式，涉及电气、结构、工艺，看设计人员如何选型，这是个人分析😃

@"freedom_liao"#p100546 为了减小厚度

@"BI1SFC"#p100547 老哥，你的端馈天线4010是镀银那款吗？不镀银的区别大不大

就是为了避免和旁边器件干涉才翘起来的。

tmp插头日系电台常用的射频连接器国内老法师喜欢称呼为“小蜜蜂”插头因为像一只蜜蜂的肚子😆

@"freedom_liao"#p100677 镀银？，你说的是阵子线吗，我这就是标配2.5平方铜线，镀银最直观，贵，在一个接近透明，更轻便，不像黑色那么显眼，实际用个人感觉不必纠结，把钱花在以后的平衡天线上

@"BI1SFC"#p100697 就是那个端馈4010天线，你说的平衡天线是什么？

What are the components in the FTX1C amplifier disassembled and lying horizontally, as shown in the image?

FTX1C 这个功放可以独立取下来，上盖和下盖螺丝都很好拆。闲来我就把机器拆开看了一下。
我看主板正面和背面，都有一个有意思的焊接头，是大约呈现45度角度立起来的，还专门做了支撑，这种一般是啥？

背面开盖照片，一堆电感继电器，内部很工整，大部分都是分立器件，不像现在的手机之类电子产品基本只有集成电路了：

正面照片没对焦拍糊掉了就不放了。

BH4FCY

Feed line connector

freedom_liao

BH4FCY What's the reason for this specific angle on the feed line connector?

BD6JYO

freedom_liao To reduce thickness

BI1SFC

看图是插头可插拔，如果放倒和PCB元器件有干涉，贴板装配也存在困难

freedom_liao

BI1SFC It seems like it might work; if a completely straight insertion takes up too much space, then a slightly angled insertion could be a compromise. 👍

freedom_liao

BI1SFC Brother, is your 4010 antenna coated with silver? What's the big difference between the silver-coated and non-silver-coated versions?

BI1SFC

freedom_liao Just like connectors and plugs, there are many different types of interfaces and methods. When choosing between them, it's important to consider the functionality and performance requirements. The specific interface and method used will depend on factors such as electrical design, structure, and manufacturing processes. Ultimately, the choice depends on the designer's judgment.😃

BI1SFC

freedom_liao Silver-plated? Are you referring to the jumper wires? I use 2.5 square millimeter copper wire as standard, and silver plating is the most straightforward option. It's expensive, but it's nearly transparent, lighter than black wire, and less noticeable. Personally, I don't think it's worth overthinking; spend the money on a good balance arm instead.

BG7NOD

This is done to prevent interference with nearby components.

BI4KSR

tmp connector, a common RF connector used in Japanese-style radios. Domestic "old masters" often refer to it as the "little bee" connector because it resembles a bee's abdomen.😆

freedom_liao

BI1SFC So, that's the 4010 antenna you mentioned? What kind of balanced antenna are you referring to?

BI1SFC

freedom_liao Dipole, inverted-V, Yagi antenna, etc.
