华鸿1.2架好了，海拔600米，差转能覆盖10公里，5瓦能打100公里的中继，但438.5直频通联不理想，有没有必要换成2.4米的？天悦和北方哪个好些？不能再长，再长不好安装了。

有条件不怕物业啥的就上520，或者钱包充足直接x700。我以前买过华鸿1.2和任丘2.4。同样位置同样电台1.2能打60km外中继，2.4打不到。

如果参数都合格肯定是越长越好这个没什么质疑的~

@"BG2EFX"#p94190 理论上讲肯定是这样的😄

@"BD4UJA"#p94160 就是囊中羞涩才纠结…手里这根华鸿1.2还行，驻波虽然不理想，但打得远😄想换长点的的，打300公里。

很难 300你需要克服地球曲率了

@"tudoubocai"#p94242 那没必要换了，可能我以前买的任丘2.4参数不行（虽然台风天也没吹断）。攒攒一口气上520吧

任丘2.4棒子差点意思，，直接搞4.8的

@"tudoubocai"#p94143 棒杆留个，搞云台+八木好了，，

@"BG2EFX"#p94265 2.4米的任丘天悦，今天架好了，手台高功率经过5米-5的馈线后，能打开300公里外的轿顶山中继，回波满格。华鸿1.2米要10瓦才能打开。另外几个几十公里、100公里的中继，回波也能满格了。就是430驻波偏高一点儿，还没调整。从431-440都在1.5以下。中心频点435，驻波1.1 15公里外，手台5瓦接华鸿518+短天线，也能轻松抄收。总的来讲，有提升，想办法调一下430的驻波就完美了。

@"tudoubocai"#p94774 两边都这么高啊？？平原羡慕了。。

Which of the Tianye or Northern 2.4G remote controls is better than the Hua Hong 1.2G remote control?

tudoubocai

The Hua Hong 1.2 is ready, at an altitude of 600 meters, with a range of 10 kilometers; it can operate as a repeater using 5 watts to cover 100 kilometers. However, the direct frequency connection on 438.5 MHz is not ideal. Is it necessary to switch to a 2.4-meter antenna? Which one, Sky悦 or Northern, is better? It cannot be extended further; longer antennas are difficult to install.

Keep one of the rods.
Okay, let's set up the Yuntai + Yagi antenna.

BD4UJA

If you have the necessary conditions, such as being able to bypass property restrictions, then use the 520 or the X700. I previously purchased the Hua Hong 1.2 and Renqiu 2.4. At the same location, the 1.2 frequency can reach 60km with a repeater, while the 2.4 frequency cannot.

tudoubocai

BD4UJA I'm just worried about having too little money... This Honhong 1.2 is okay, and while the "Zhu Bo" isn't ideal, it still hits far.😄If you want a longer one, I can get it for you, covering a distance of 300 kilometers.

BG2EFX

If all parameters are satisfactory, then longer is definitely better. There's no question about this.

tudoubocai

BG2EFX Theoretically, this is exactly how it works.😄

BD4UJA

tudoubocai I don't need to replace it, maybe the previous one I bought with the Renqiu 2.4 specifications wasn't suitable (although it didn't break even during a typhoon). Let's save up and buy the 520 version instead.

It's difficult to maintain a straight line when you need to account for the curvature of the Earth.

tudoubocai

BG2EFX 2.4-meter Renqiu Tianyue, which I set up today, with a handheld transceiver and a 5-5 meter feed line, can now operate the 300km away Cedongshan repeater, achieving full signal strength. The Hua Hong 1.2m requires 10 watts to operate. Several other repeaters within 几十公里 (dozens of kilometers) and 100 km also achieve full signal strength.
Specifically, the 430 frequency is slightly higher than expected and hasn't been adjusted yet. The frequencies between 431 and 440 are all below 1.5. The center frequency is 435, with a standing wave of 1.1.
At a distance of 15 kilometers, using a 5-watt handheld radio with a Huawei 518+ antenna, it is easy to receive signals.
Overall, there's room for improvement. If you can find a way to adjust the 430 frequency, it will be perfect.

BH9FPK

The Renqiu 2.4 inch antenna is similar in function; I'm going to use a 4.8 inch one instead.

BG2EFX

tudoubocai Both sides are so high! The plains must be envious.

tudoubocai

BG2EFX On one side, there was a 3500; on the other side, there was a 600. There were no high mountains blocking the view between them.
