看着论坛HAM介绍过，八重洲891短波机，配合八重洲120自动协调短波天线，效果不错。自己动手买了设备，安装完毕，期待通联效果能好点。

上安装效果图，再看看通联效果

八重洲 120 可不便宜，之前的反馈是，能用！但效果远不如正儿八经的倒V正V。毕竟GP天线本来底噪就高，影响到接收；而120的底部加感方式，只是能保证驻波比，但无法保证实际发射功率。 👍期待楼主的评测。

120的话可以去黄鱼搜一个改装接头然后就可以上拉杆了。。

🤤楼主指点一下装车方案吧，我这边也想装车，但是对于固定在哪比较头疼，主驾附近没啥空间。并且还有取电的方案，电瓶取电是加了个继电器防亏电吗。

话说有没有什么短波八木推荐的…… 短波八木推荐自制还是购买……

891装车为了移动中短波通联？预计你用不了多久就拆了。属于理想丰满现实骨干投入高产出很低的玩法。野架的话也不用安装到车上，几分钟随便立根拉杆GP天线都比那车载天线强太多。

@"Ubuntu"#p74318 建议购买，自制做做UV段就好了，毕竟是个大件，安全第一

Yaesu 891 Shortwave Receiver - Mobile Version

BG4CLH

I saw an introduction on the forum about the Yaesu 891 shortwave radio, combined with the Yaesu 120 automatic shortwave antenna, which seems to have good results. I bought the equipment myself and installed it, and I'm hoping for better communication performance.

Let's take a look at the results of the photos.

Here are the installation effect diagrams, and then let's look at the communication effect.

The Yaesu 120 isn't cheap, and previous feedback indicated that it works. However, the results are far inferior to those of a genuine, properly designed V-type antenna.
After all, GP antennas inherently have high baseline noise, which affects reception. Furthermore, the bottom-up impedance matching method with a 120 resistor only ensures the standing wave ratio (SWR), but cannot guarantee the actual transmitted power.
👍Looking forward to your review, OP.

If you have 120 words, you can search for "yellow fish" and find a modified connector, then you can install the handle.

🤤Could someone please provide some guidance on the installation scheme? I'm also planning to install a solar system, but I'm having trouble deciding where to mount it. There isn't much space near the driver's seat. Also, could you tell me if you used a relay to prevent battery drain when taking power from the battery?

Speaking of which, are there any shortwave Yagi antennas that you would recommend?

Ubuntu I recommend purchasing one. If you make it yourself, you can easily create a UV segment. After all, it's a large item, and safety is paramount.

Using a 891 transceiver for shortwave communication? You'll likely find that it quickly becomes obsolete. This is a high-output, low-yield strategy, suitable for those seeking realistic and achievable results.
You don't even need to install a "野架" (wild-mounted) antenna on your car; a simple, freestanding GP antenna is much better than the car's built-in antenna.
