华鸿HH-S518+（8cm）怎么样

我个人使用宝锋5RH PRO手台和华鸿S518+以及跟原装天线对比，还是原装天线好一些

感觉网上吹捧比较多，买回来拿驻波表一测，比原装差不少，也可能是我买的那个个体差异问题。

挺好用的，一是便携，二是耐摔

便携确实是主要优势。要说耐摔的话，网上有说法是有时可能把中心频点摔偏，我倒没有遇到过（摔过两次之后用NanoVNA测试过正常）。要说灵敏度和增益，我没有量化测试，但这几天在郑州北郊某地打中继，明显能感觉到比UV-K6原装天线弱一些。

你的手台原装天线如果长度差不多，就没必要买了。

我的全盛UVK6用的，感觉就这样吧，主要是为了便携!

天线这东东一寸长一寸强这是物理规律

@"BI1NKD"#p81897 个体问题（可能是伪的），我回来测中心频率435.340Mhz，驻波1.12，144.400Mhz，驻波1.35。 438.500 1.21 145.100 2.37

@"BI3AYR"#p81901 我觉得我有必要补充一下了，这个耐摔是看运气的。之前和AYQ去北京的时候摔在马路上，天线着地，一点问题没有。前两天从桌上掉在地上水平着地，今天一测驻波变7了。

What are the pros and cons of the Hua Hong HH-S518+ (8cm)?

What are the pros and cons of the Hua Hong HH-S518+ (8cm)?

arwoon

Personally, I found that the original antenna performed better than the BaoFeng 5RH Pro handheld radio and the Hua Hong S518+, when compared side-by-side.

BH1AYY

arwoon Haha, everything from BaoFeng is terrible.

BI1NKD

I felt that there was a lot of hype online, so I bought one and tested it with an antenna analyzer. It performed significantly worse than the original, and it could also be due to the specific unit I purchased.

pyxmr2025

BI1NKD Individual issues (possibly spurious), I re-measured the center frequency at 435.340 MHz, with a VSWR of 1.12 at 144.400 MHz, and a VSWR of 1.35.
438.500 1.21 145.100 2.37

BI3AYR

It's very useful; firstly, it's portable, and secondly, it's durable.

BI3AYR

BI3AYR I feel I need to add something: the "drop-resistance" is largely a matter of luck. When AYQ and I were in Beijing, it fell onto the road and didn't have any problems, even though the antenna was on the ground. Two days ago, it fell from the table and landed flat, but today I checked and the standing wave factor has increased to 7.

Ken

Portability is definitely a major advantage. As for durability, there are claims online that the center frequency can be affected if dropped, but I haven't personally experienced this (after dropping it twice, I tested with a NanoVNA and found it to be normal).

Regarding sensitivity and gain, I don't have any quantitative tests, but over the past few days while using a repeater in a location north of Zhengzhou, I can clearly feel that it is weaker than the original UV-K6 antenna.

tudoubocai

Ken As I said, once the center frequency changes, it becomes unstable. You can adjust it yourself.

Liridice

If your existing handheld radio has an antenna of similar length, you don't need to buy a new one.

BI3SKL

I used the full-size UVK6 and found it to be just fine, mainly because of its portability!

CQ-BG8LTU

手上一个公头的HH-S518+，测驻波看起来还将就。
但是用在欧讯UV-2Q，U段勉强能用，但是V段相当于没有。

后面又在闲鱼上买了一个母头仿华鸿的XX-518+天线用于UV-K6。

在同一位置，使用仿制天线的K6能打开V段中继，使用华鸿天线的UV-2Q就无法使用。

但是总归来说，这种短天线除了便携，天生不占优势。

BA4QBK

This antenna – just one inch long, yet incredibly strong – demonstrates a fundamental physical principle.

BH1AYY

pyxmr2025 Regarding industrial testing?

Watermelon

Its existence was solely for a short period.

BG7MGW

BI3AYR I also dropped it, and the SMA connector was slightly bent. The resonant point didn't change. You can open it up and re-adjust it internally. Then, you can use a spare SMA male connector and pull it out with pliers.

BI3AYR

BG7MGW Thank you for your reply. I've been quite busy lately, so I'll take some time off during my vacation to catch up.😂
