刚刚装了车载天线，就想装个大功率手台放车里，艾迪欧uv99怎么样，还是森海克斯G-12，我想带个UV频差功能，这样拿车内手台当中继思路对吗，使用效果如何呢？还有别的什么建议吗？小白一枚，刚刚考完试，谢谢

大功率和手台根本就不划等号

车内再大功率效果都不会好的啦，你车体内部就相当于一个法拉第笼，只靠玻璃窗辐射一点信号出去。如果是偶尔用一下的，看看预算买个自己看着顺眼的10W机，最好再引天线出车外。如果经常用还是上个车台好

重要的是天线，如果只是本地上中继随便啥手台外接一个磁吸的天线放车顶都行，出行也能直频通个几公里（无遮挡）

冠星 GX8500 闲鱼售价299元基础芯片:BK4819 功放:太华电子HTL7G06S011P 7.2V 11W (电池12V超压，使得功率达到20W) 电池:12V三元锂 12伏 V段发射稳定20W U段稳定17瓦 11伏 V瞬时17.8W 稳定17W U瞬时17W 稳定15W 145发射三次谐波435低于主频57.6dBm 435发射三次谐波1305低于主频60dBm

我在车外安装了一个0.7米的车载天线

没必要，既然车载天线装好了，把手头现有台子接上去就行，接头不对的话就去买转接头，例如SMA母转M母的想做中继，要装专门的车台和双段天线，还要有人陪你玩

@"luckyum"#p79440 UV段高度>天线>功率，找个高度足够的地方原装天线都能打很远，理论上功率提高4倍传输距离才提高一倍，随便找个类似DM32UV这种10W的手台就足够了

感觉随便找个10W手台就行，兼顾平常带着和车载。我车顶也是吸了个70cm的短天线，因为车体当地网的缘故，通联距离比正常手台会远很多。我自己就是用K5。5W随缘通。

意思是实际上用车外天线 G12和UV-99 ，15瓦和10瓦差不了太多吗？如果在户外15瓦就比10瓦远一点点吗。

Please recommend a high-power handheld radio.

I just installed a car antenna and am considering buying a high-power handheld radio. What do you think of the iRadio UV99, or the Senhaix G-12? I'm looking for a unit with UV (Ultra Violet) frequency offset capability so that I can use it in conjunction with a repeater. How would this setup work, and what are your thoughts on its effectiveness? Do you have any other recommendations for a beginner like me who just passed the exam?

High-power radios and handheld radios are completely different things.

The power output won't be any better inside the car. Your vehicle's interior is essentially like a Faraday cage, and it only emits a small amount of signal through the windows. If you only use it occasionally, consider buying a 10W unit that looks good to you within your budget, and ideally, add an antenna to the outside of the car. If you use it frequently, a separate car kit is better.

It's important to have a good antenna. If you're just using a local repeater, any handheld radio with an external magnetic mount antenna that can be placed on the roof of your car will work. This allows for direct communication over several kilometers (without obstructions).

The Guanxing GX8500 is being sold on Xianyu for 299 yuan.
Base chip: BK4819
Amplifier: TH Audio HTL7G06S011P, 7.2V, 11W
(Battery overvoltage at 12V, resulting in power reaching 20W)
Battery: 12V 3-cell lithium

12V
V-segment transmit stable at 20W U-segment stable at 17 watts

11 volts
Instant: 17.8W; Stable: 17W
Instant 17W, stable 15W

145 transmit, three harmonics below the main frequency at 57.6 dBm
435 transmit, three harmonics at 1305 are below the main frequency by 60 dBm.

I installed a 0.7-meter vehicle antenna on the exterior of the car.

luckyum UV segment height>Antenna>Power, find a location with sufficient height where the original antenna can reach far. Theoretically, increasing power by 4 times only increases transmission distance by one time. Any handheld transceiver like the DM32UV (10W) is sufficient.

BG4IJK

It's not necessary. Since the car antenna is already installed, simply connect the existing device to it. If the connection doesn't match, purchase an adapter, such as an SMA female to M male adapter.

If you want to set up a repeater, you'll need to install a dedicated chassis and a dual-element antenna, and someone to operate it with you.

I think I can get by with just one 10W handheld radio, for both everyday use and in the car.
I also installed a 70cm short antenna on my car roof because, due to the local network conditions, the communication distance was much further than that of a normal handheld radio.
I personally use a K5.5W transceiver.

luckyum

The meaning is that in practice, the difference between using an external antenna (G12) and a UV-99 with 15 watts and 10 watts power output is not significant?
Would a 15-watt light be noticeably brighter than a 10-watt light outdoors?

BG4IJK

luckyum If you have local repeater coverage, 1W should be sufficient. If 5W isn't enough, it's likely a location issue.

luckyum

BG4IJK Can I connect to a repeater while driving in my car? For example, will there be a significant difference between using a UV-99 and a GT-12?

BG4IJK

luckyum First, try using your existing equipment. If it doesn't work, improving the performance of a high-power handheld device will only have limited effects. Don't rush to buy new equipment.

luckyum

BG4IJK I'm looking to buy a high-powered handheld radio, and I plan to use it in my car. Whether or not I need a specific model doesn't matter; the radios I already have are perfectly functional for me.

The 5W and 10W models are not effective, and neither is the 25W model. Currently, only the GX8500 from Guangxing has been approved for use at 25W.
IThis postYou can refer to it for reference.

luckyum

So, for now, I'll use my own handheld device in the car. I'll add another one later if needed. Having a car-specific antenna makes a big difference though; it allows for 8 watts of transmission.
