买了个宝锋uv32，原装天线，还买了根鹅颈天线，有次刷到个直播间说，原装天线更好，适配性更好，难道单独买的几十块的天线没有原装的好？求解答

具体还是看天线型号和应用场景吧曾经碰到过NWV775和SRJ77都接收不到，但K6原装天线可以接收的微小信号，也有原装一片寂静，但是SRJ77一清二楚的FT8信号更多的情况是类似于NWV775 SRJ77这种第三方天线对接收有正面效果业余天线确实够玄的，除了能看个增益数值，好不好用纯凭口碑，很少有辐射图这种量化的内容

原装天线应该是对机器能接收发射的频率都可以，市场上的天线是专门对某个频率增益高，其他频率不行

选业余双段的天线，其他的类型的在业余段发射效果做的不行。原装天线一般在U段是400-470mhz在业余段效果很一般，昨天找老HAM，跟我讲的，业余最好是选 144-146/430-440mhz的天线，大概八十-二百左右的价位，反正挺贵的（毕竟无限垫XD），原装天线为了范围大点，质量不怎么样其实

不一定我手里的hh518+就很不错的嘞

看指标，我用过的原装天线，最好的是森海克斯uv12pro的鹅颈天线，第二是艾迪欧uv88，第三是宝峰uv5rh，最差的是uvk6的。k6这个还不如518+ 在指标都好的情况下，越长效果越好。如果指标不好，长天线也没用

Are antennas that cost less than 50 yuan/RMB worse than the original antenna?

I bought a BaoFeng UV32, with the original antenna. I also purchased a gooseneck antenna. Recently, I saw someone on a live stream saying that the original antenna is better and has better compatibility. So, why would a separately purchased antenna for around 40 yuan/RMB be better than the original one? Please advise.

Ultimately, the choice depends on the specific antenna model and the application scenario.
I have encountered situations where both NWV775 and SRJ77 were unable to receive signals, but the original K6 antenna could receive even very weak signals. Conversely, I've also experienced instances where the original antennas provided no reception, while SRJ77 clearly received FT8 signals. The most common scenario is that third-party antennas like NWV775 and SRJ77 provide a positive effect on receiving.
Amateur antennas are indeed quite mysterious. Besides being able to see a gain value, their effectiveness is largely based on word-of-mouth, and there's rarely any quantitative data like radiation maps available.

The more unusual the antenna, the worse its performance.

The original antenna should be capable of receiving and transmitting on all frequencies that the machine needs. Antennas available on the market are specifically designed for high gain at a particular frequency, but not others.

Choose a dual-band amateur antenna; other types of antennas do not perform well in the amateur band.
The original antenna typically operates in the UHF band (400-470 MHz) and performs poorly on the amateur radio frequencies. I spoke with an experienced HAM yesterday, who suggested that for amateur radio, it's best to choose a different antenna.
The antenna in the range of 144-146/430-440 MHz, priced around $80-$200 (expensive, especially considering the unlimited XD), and the original antenna had a poor quality due to its larger coverage area.

Not necessarily. My HH518+ is quite good.

Based on the performance, the original antennas I've used were: the best was the Senhaix UV12Pro's gooseneck antenna, followed by the iradio UV88, then the BaoFeng UV5RH, and the worst was the UVK6. The UVK6 performed worse than the 518+.
Even when all indicators are good, a longer antenna will provide better results. However, if the indicators are poor, a longer antenna will not be effective.
