2. Regarding the video transmitter, what are the frequencies available?

There are three frequencies to choose from 800Mhz, 1.2G, and 2.4G. But there is no 10W Power Amplifier for 150km at 2.4Ghz. So if the buyer wants to support a 150km transmission distance, only 800Mhz and 1.2G can be chosen.

3. Can you take a test video for me to see before shipping?

Of course, we also understand that wireless video transmission transmitters and receivers are very expensive. You are far away from the China factory. and hope that the goods you receive are fit for the best performance. If you pay special attention to a specific parameter or function, we can take some test videos based on the features you want to see, please feel free to contact us. It won't be shipped to you directly without your approval. Just like today, I tested and show the video to my client.

4. Can I use one 3-meter RF cable from the transmitter to the antenna?

Regarding the RF cable, our engineer doesn't recommend that you used so long. There will be a reduced 0.5dB for one meter RF cable. For 3 meter RF cable, the signal strength will be reduced by 1.5dB.

6. What types of video inputs port does your wireless video transmitter have?

Our wireless video transmitters have these types of video input interfaces: HDMI 1080P and 4K HDMI, CVBS composite, SDI, AHD, IP Ethernet, and BNC, or tell us what type you need, and our engineer will modify it to meet your demand.

7. What is the transmission distance supported by your wireless video transmitter?

Our transmission distance can be adjusted by adding power amplifiers. At present, the main ones are 15km, 30km, 50km, 80km, 100km, and 150km, which depend on the needs of customers. Of course, the transmission distances listed above are all within LOS the line-of-sight range. If there are obstacles between the transmitter and the receiver, NLOS (the non-line-of-sight), the transmission distance is greatly reduced, only 1km or 2km, depending on the number of intermediate obstacles and the local wireless environment.

8. What is one-way or two-way? Simples vs half-duplex, full-duplex

One-way means, We can only transmit and download video or data from the wireless video transmitter to the receiver in one direction, and we cannot upload video or data from the receiver to the transmitter. This type is also called simplex. Two-way means that, not only we can download video or data from our wireless transmitter to the receiver, but also we can upload the video or data from the receiver to the transmitter. This is very suitable for operating drones. You can not only see the real-time video transmitted from the drone but also upload the command to control the drone or the command to control the PTZ camera to adjust the angle to the transmitter. This can operate simultaneously. This type is also named half-duplex or full-duplex.

9. Does your HDMI video transmitter support encryption and receiver decryption?

Most Wireless video transmitters now support AES128 or AES256 bit encryption and decryption, depending on which model you choose. Please contact us to verify.

10. Can the frequency of the wireless video transmitter be modified after ordinary users receive the goods?

The frequencies of both the wireless video transmitter and the wireless video receiver can be modified. Users need to purchase additional parameter configuration boards. However, considering that the corresponding power amplifier and antenna are already fixed within a certain range when the goods are sent out. If the user adjusts the frequency of the transmitter, the corresponding power amplifier, transmitter antenna, and receiver antenna should also be modified to the same frequency, and these users need to be prepared. If not, it will cause the frequency of the wireless video transmitter to be different from the frequency of the antenna, making reception difficult. So please be sure to inform the correct frequency you need before placing an order. If it is for security or confidentiality, you can use the encryption and decryption functions of the transmitter and receiver, which can ensure that your video transmission is private.

11. I saw that your model is very similar to my needs, but I need to modify one of the parameters, is that possible?

Yes, all our product parameters can be customized according to customers' needs. If you have a special request, please let us know.

13. Can I buy modules of the transmitters and amplifiers only? I want to assemble them into my equipment.

We can, of course, supply wireless video transmitter modules and power amplifiers. For the first sample test, I recommend that you purchase the entire set of products because our engineers have optimized the parameters to achieve the best performance. After you have completed your test verification, you can remove the case or heat sink, install it on your device, and constantly adjust the parameters to achieve the best performance. In the future, you will be able to purchase only the modules or accessories that you require.

無線視頻數據音頻發送器和接收器, 雙向, Download-Upload

A customer saw our real test video about the 2 瓦功率放大器 27km 遠程無線視頻發射器和接收器. He placed an order for this equipment. He hoped we would also bring the transmitter to the top of the mountain and the receiver to the seaside for testing before shipment. We have done our best to meet the needs of the customers. So we did it and created today’s video. If you want to learn about the actual transmission effect of long-range HD 1080P wireless video transmission, as well as how to operate it. Please keep watching.

Let’s begin by looking at the test location and distance on Google Earth. Search Meishajian, which is located on Shenzhen’s third highest peak, for no obstructions and simulate the situation of an aircraft with a transmitter in the air, ensuring that the test is within the line of sight. There are many high-rise buildings in a coastal city like Shenzhen. Finding a test environment with a line of sight and a distance of 30 kilometers is difficult. A T-shape is formed from here to the seaside of Nan’ao. Our receiving station is on the beach, and we can see the top of the transmitter from a distance of 27 公里.

We used the good distance tool to determine that the distance between the transmitter and the receiver is nearly 27km. In the following video, we can see from the receiver’s web UI page that the current transmitter to receiver distance is 27390 米.

Now let’s take a look at the situation of the transmitter on the mountain. The transmitter, IP network camera, and battery are placed on the rock. The trekking pole and red bubble belt make a red flag, which is fluttering in the wind so that the picture on the receiver screen is not static, it can be observed whether the wireless transmission video is smooth. The receiver is on the other side of the sea. The black transmitter is connected to two 30cm height transmitting antennas, the left part is the IP network camera, which is connected to the transmitter with a network cable, and the right part is a 12V battery, which powers the transmitter and the IP network camera.

Please try to position the transmitter and receiver vertically while transmitting. The signal strength will then be strong. Allow me to turn the transmitter and receiver in my hand, and the receiver monitor video will begin to move. The receiver will determine whether or not the video is smooth.

Now let’s take a look at the picture of the receiver.

The receiver is connected to the computer through the network cable. We can use the RTSP player on the computer and see the smooth picture directly.

We can also enter 192.168.8.11 in the browser to open the setting page of the receiver. On this parameter setting page, we can see various parameters of the current transmitter and receiver. An important parameter in this table is the distance and the signal strength. Now we can see that from the current transmitter to the receiver distance is 27390 米.

In the computer’s RTSP player, we can see that the wireless video transmission picture from the mountain transmitter has been kept very smooth, and the little red flag and the grass are fluttering in the wind without any lag, frozen, 馬賽克.

We are using an IP network camera to test, if your camera has HDMI 1080P, 4K HD, SDI, AHD, or CVBS output, we also can add an encoder to the transmitter, connect your video output, and send out the IP living streaming to the transmitter. 在接收器, output the video to a computer through a network cable, or to a network video recorder.

It can be seen that the picture is very smooth,

Here we continue to play the videos recorded by the transmitter and receiver on the computer, and we can also answer some questions that some clients care about and always asked.

Two-Way full duplex Wireless Video Data Audio Transmission

第一, this set of wireless video data transmission transmitters and receivers is a two-way full duplex transmission system, it is like setting up an invisible wireless network in the air, two computers can be connected, and ping can be used in the computer’s cmd command state. In addition to transmitting video, data and audio can also be transmitted.

Power Amplifier options 2W, 5W¯¯, and 10W to support longer distance

第二, if you want to support longer distances, we can achieve longer distances by changing different amplifiers. 例如, 300毫瓦, 2 瓦特, 5 瓦特, 10 Watts power amplifier, the corresponding transmission distance is 7 千米, 15 千米, 30 千米, 80 千米, 100 千米, the farthest can be transmitted to 150 千米, we also have a 110 km The actual test video. If you are interested, I can also edit it and upload it for everyone to watch.

Up to 150Km, 4 times of English Channel Width

第三, what is the concept of supporting up to 150 公里? It is equivalent to 93 英哩. The UK is separated from Europe by the English Channel, and its width is only 35 公里, 那是, 150 kilometers is equivalent to the width of 4 times English Channels. It can also transmit high-definition videos with good signals.

Video Download, UART Data TX RX,

第四, if you need to control the PTZ camera, the receiver can also send control commands to adjust the direction and movement of the camera. This set of Wireless video data transmission transmitters and receivers also has three RS232 data interfaces, which can transmit various commands and data, and even connect with the drone’s flight control to remotely operate the drone.

AES 128 to protect video data safety

Fifth, this wireless video transmission device also supports aes128 for video encryption and decryption, so you don’t have to worry about your video, not safety, or being intercepted by others.

Two-Way Video Data Link Module + 功率放大器

Sixth, Today we used 2 瓦功率放大器. If your project demand, you can also purchase the two-way Wireless video data audio transmission transmitter and receiver module, and then configure your power amplifier.

1. What battery should I prepare for this 2 瓦特, 5 瓦特 10 Watts Power Amplifier transceiver?

2 Watts needs a 12V Power Supply, 5 Watts needs a 24V power supply, 10 Watts needs a 28V power supply

2. 關於視頻發射器, 可用的頻率是多少?

There are three frequencies to choose from 800Mhz, 1.2G, 和2.4G.
但是2.4Ghz下150公里沒有10W功率放大器. So if the buyer wants to support a 150km transmission distance, 只能選擇800Mhz和1.2G.

3. 你能在發貨前拍一個測試視頻給我看嗎?

當然, 我們也了解無線視頻傳輸發射器和接收器非常昂貴. 你離中國工廠很遠. 並希望您收到的貨物適合最佳性能.

如果您特別注意特定的參數或功能, 我們可以根據您想看到的功能拍攝一些測試視頻, 請隨時與我們聯繫. 未經您的同意，不會直接發貨給您. 就像今天一樣, I tested and show the video to my client.

4. 我可以使用一根 3 米長的射頻電纜從發射器到天線嗎?

關於射頻電纜, our engineer doesn’t recommend that you used so long. 一米射頻電纜將減少 0.5dB. 對於 3 米射頻電纜, 信號強度將降低 1.5dB.

5. It seems that your transmitter is supporting an IP camera, but my video source camera is HDMI or SDI video output, 我該如何使用這個發射器和接收器？

是, 默認視頻輸入為 IP RJ45 以太網電位器, if your camera is HDMI or SDI or AHD, 只需加一個小編碼器盒即可解決此問題, this encoder box will output IP living stream to the transmitter.

6. 您的無線視頻發射器有哪些類型的視頻輸入端口?

我們的無線視頻發射器有這些類型的視頻輸入接口: HDMI 1080P 和 4K HDMI, CVBS複合材料, SDI, AHD, IP以太網, and BNC, or tell us what type you need, and our engineer will modify it to meet your demand.

當然, the transmission distances listed above are all within LOS the line-of-sight range. 如果發射器和接收器之間有障礙物, NLOS (非視線), 傳輸距離大大縮短, 只有1公里或2公里, 取決於中間障礙物的數量和當地的無線環境.

8. 什麼是單向或雙向? 單工與半雙工, 全雙工

One-way means, 我們只能從無線視頻發射器向接收器單向傳輸和下載視頻或數據, 我們無法將視頻或數據從接收器上傳到發射器. 這種類型也稱為單純形.
Two-way means that, 我們不僅可以將視頻或數據從無線發射器下載到接收器, 但我們也可以將視頻或數據從接收器上傳到發射器. 這個非常適合操作無人機. You can not only see the real-time video transmitted from the drone but also upload the command to control the drone or the command to control the PTZ camera to adjust the angle to the transmitter. 這可以同時操作. This type is also named half-duplex or full-duplex.

9. 你的HDMI視頻發射器是否支持加密和接收器解密?

Most Wireless video transmitters now support AES128 or AES256 bit encryption and decryption, 取決於您選擇的型號. 請聯繫我們進行驗證.

10. 普通用戶收貨後可以修改無線圖傳的頻率嗎?

The frequencies of both the wireless video transmitter and the wireless video receiver can be modified. 用戶需另外購買參數配置板.
然而, 考慮到貨物發出時相應的功放和天線已經固定在一定範圍內. 如果用戶調整髮射機的頻率, the corresponding power amplifier, 發射天線, and receiver antenna should also be modified to the same frequency, 這些用戶需要做好準備. 如果不, 會導致無線視頻發射器的頻率與天線的頻率不同, 使接待困難. 所以請務必在下單前告知您需要的正確頻率.
如果是為了安全或保密, you can use the encryption and decryption functions of the transmitter and receiver, 這可以確保您的視頻傳輸是私密的.

11. 我看到您的模型與我的需求非常相似, 但我需要修改其中一個參數, 那可能嗎?

是, all our product parameters can be customized according to customers’ needs. 如果您有特殊要求, 請告訴我們.

12. 無線視頻接收器信號弱怎麼辦?

1. Change the place of the receiver to avoid potential local interference from magnetic solid environments.
2. Ensure that the antennas on both the transmitter and receiver are vertical.
3. Please raise the antennas of the transmitter and receiver to maintain a particular height difference.
4. Please look around to ensure that there are no obstacles between the transmitter and receiver.
5. Change the orientation of the receiver antenna.
6. If it doesn’t work, try moving the receiver to be near the transmitter’s position to see if it exceeds the effective wireless transmission distance.
7. Or consider adding a relay of the transmitting between the transmitter and receiver.

13. 我可以只購買發射器和放大器的模塊嗎? 我想將它們組裝到我的設備中.

27km-test-distance-from-wireless-video-transmitter-and-receiver — 27km-遠距離無線視頻發射接收器

常見問題

1. 這個10W功放收發器應該準備什麼電池?

本發射器的電源和電池都是 3A@28V. 平時, 我們用來測試的電池是7AH, 可以工作2~4小時. 如果購買15AH充電電池, 可連續工作約4~8小時.

2. 關於視頻發射器, 可用的頻率是多少? 我們可以選擇嗎 2.4 GHz 作為選項還是必須是 1.4GHz 或 800MHz?

800Mhz有三種頻率可供選擇, 1.4G, 和2.4G.

但是2.4Ghz下150公里沒有10W功率放大器. 所以如果買家想支持150km的傳輸距離, 只能選擇800Mhz和1.2G.

不僅在 web UI 參數處輕鬆切換頻率, 改變頻率後, 它還需要改變內部的功率放大器和相同頻率的發射和接收天線. 所以買家應該在發貨前確認你需要的頻率. 天線是根據這個頻率定制的.

3. 我可以使用一根 3 米長的射頻電纜從發射器到天線嗎?

關於射頻電纜, 我們的工程師不建議您使用它這麼久. 一米射頻電纜將減少 0.5dB. 對於 3 米射頻電纜, 信號強度將降低 1.5dB.
為了支持遠距離, 最好使用小於 RF 電纜 1 儀表?
事實上, 發射器非常小, 發射器到發射器天線最好保持較短的距離. 發射器的電源線和從相機到發射器的以太網電纜可以更長，因為沒有射頻電纜那樣的損耗.

4. 好像支持網絡攝像機, 但我的視頻源或攝像頭是 HDMI 或 SDI 視頻輸出, 我該如何使用這個發射器和接收器？

是, 默認視頻輸入為 IP RJ45 以太網端口, 如果你的 相機是 HDMI 或 SDI 或 AHD, 只需加一個小編碼器盒即可解決此問題. 請檢查以下型號.

HDMI SDI AV input encoder IP RJ45 Ethernet output — HDMI SDI AV 輸入編碼器 IP RJ45 以太網輸出

5. 我應該選擇 800 Mhz 或 1.4G 以獲得更好的接收效果? 有1.4G干擾GPS天線?

如果您所在地區有 DVB-T 或 DVB-T2 數字電視信號, 該 電視頻率範圍為170-860Mhz, 它包括800Mhz, 所以選擇1.4G比較好.
因為GPS天線接收到GPS信號，無人機上的GPS方向是向上的, 我們的發射器天線指向下方以將信號發送到地面. 因此, 1.4G頻率對GPS的影響可以忽略不計.

6. 一套的包裝怎麼樣? 毛重及尺寸?

包裝尺寸為 125 X 23 × 11 厘米. 總重量：3.72公斤，體積重量：7.5公斤

7. 我應該在參數設置中將跳頻設置為是嗎?

關於跳頻, 工程師有一些建議給你.

由於系統頻率範圍為20Mb, 如果您的帶寬選擇 20Mb, 那麼它不能跳 (只有一點). 如果帶寬選擇10Mb, 那麼你有兩點可以跳, 如果選擇帶寬 5Mb, 那麼你有 4 跳點.
如果1410Mhz卡住了, 然後1420Mhz也卡了, 因為頻率太接近.
跳頻時, 數據或視頻傳輸將斷開, 你的視頻將被凍結.
平時, 最好選擇 hopping is NOT.
如果您的傳輸距離小於15~22km, 那麼我們還有另一種選擇, 頻率有110Mb, 即使您選擇 20Mb 帶寬, 它有 5 可供選擇的跳頻點.

8. 此型號是否支持多發射器相機到一個接收器? 例如, 使用 3 網絡攝像機位於 1 視頻傳輸器.

是, 它支持.

多發射機相機到一個信號接收器有兩種解決方案.

9. 你的雙向無線視頻數據音頻鏈接模塊是否支持sbus for inav?

如果需要支持S.bus, 那麼請在發貨前告訴我們, 我們將把我們的 RS232 修改為 TTL.

我們的TX900有3個RS232接口. 如果你需要它來支持 S.bus, 只需要加一個小的S.BUS轉RS232的轉換器就可以了. ( Mini SBUS 轉換模塊 Uart 轉 Sbus, 總線轉串口 ).

10. 我們怎樣才能得到RSSI, 信噪比快, 去調試會話, 無需登錄網絡; 你有AT命令來獲取這些信息嗎?

客戶需要RSSI無線鏈路狀態數據 (例如飛行控制器) 手動發送AT指令獲取. 可以透過兩種方式獲得:

配置UART3 (數據連接埠第三) 作為AT指令串口, 然後透過UART3發送AT指令 (D3) 獲得. https://ivcan.com/change-d3-from-transparent-serial-port-to-at-command/
更新韌體版本 1.5.1 以上, 這樣內部就會多一個TCP伺服器，讓客戶透過TCP存取發送AT命令取得無線狀態.
LED燈用於指示無線連線狀態 (例如, 如果無線連結斷開, 燈將會熄滅), 並且沒有專門的外部引腳通知客戶飛控.

或者參見串口 AT 命令列表這裡.

11. 這些空中模塊是否向飛行控制器發出故障保護命令空中和地面模塊之間的連接何時丟失?

我們無線圖傳的串口是透明的, 並且沒有數據主動發送到飛行控制器. 這是由地面站控制的.
它不會發送故障保護命令, 但您可以從信號指示燈中看到鏈接狀態燈.
這裡是鏈路狀態信號強度指示器的意思
1. 不亮: 表示模塊的無線鏈路未連接
2. 紅: 表示模塊的無線鏈路已經連接, 但是無線信號強度很弱
3. 橙子: 表示模塊的無線鏈路已經連接, 無線信號強度中等
4. 綠色: 表示模塊的無線鏈路已經連接, 而且無線信號強度很強
我們了解您希望擁有此功能, 如果飛機在飛行過程中失去信號，它將不會返回家中，因為飛行控制器不會理解 rc 鏈路丟失.
您需要查看鏈路狀態 LED 燈, 如果它是橙色或紅色, 你應該提前把飛機控制回來.
您還可以在下面的窗口中獲取 RSSI

12. 無線圖傳收發器如何升級最新固件

請檢查升級固件setps, 在下面的鏈接下載最新的升級固件.

13. 您的系統是否能夠使用 3 節點? 因為我們必須使用第三個節點作為發射器和接收器之間中心的中繼器.

在正常使用, 一個節點作為發送者, 另一個節點作為接收者. 如果您需要支持遠距離或越過山頂, 像下面的圖片, 是, 請購買 3rd nord 作為 reapter.
您只需要將第 3 個節點放在中間並將第 3 個節點設置為 2D3U 然後就可以了.

如何設置第 3 個節點為 2D3U?

用AT指令設置:
在+cfun=0
在 ^dstc=0
在+cfun=1

15. 你的無線視頻發射器支持4K視頻嗎?

4支持K視頻.
4K視頻流一般都有8Mbps以上, 而1080P的視頻一般都有2M以上, 所以我們在傳輸4K視頻時無線圖傳的距離會比1080P短.

總而言之, 視頻的清晰度越高, 傳輸距離越短.
視頻壓縮更小, 支持傳輸距離更遠.

16. 發送視頻信號時, 如果數據包在傳輸過程中丟失, 接收方是否通知並要求發送方重新發送丟失的數據包?

視頻傳輸過程中, 如果有數據丟失, 圖片會出現馬賽克或停滯, 凍結等現象.

無線鏈路級別的重傳次數有限 (當然, 情況不好也會出現數據錯誤). 端上層應用不會感知到, 也不會要求發件人重傳.

如果距離拉遠後某個點無線鏈路信號不好, 並且總是有位錯誤, 不可能一直設計重傳, 這樣最終用戶體驗會很差.

無線鏈路層有有限的重傳機制. 我們在視頻傳輸層測試了tcp協議進行傳輸 (試圖通過tcp協議在上層重傳), 但是測試發現沒有明顯改善, 而且還會導致無法控制的延誤.

17. 發射器很燙怎麼辦?

飛行器側產生的熱量遠大於地面側. 如果風扇運轉, 檢查下風扇的進風口和出風口是否 (兩端散熱片位置) 被封鎖
嘗試將空中單元發射器的電源從24V改為12~18V (發射功率會降低到35~36DB左右)
通過以下 AT 命令稍微降低飛行器的發射功率: AT^DSSMTP="23" 設置後重啟

題: 這些設置是模塊的最大功率嗎? (24 dBm的)

回答: 24dBm是鏈路模塊的最大輸出功率, 和PA的增益 (約14dBm) 需要添加. 24V供電PA輸出後實際發射功率約38dBm.

18. 你能填寫下面的表格向我們展示更多信息嗎?

19. 是否可以將地面單元用於空中單元，反之亦然，並更改設置?

空中單位的區別 (發射機) 和地面單位 (接收器) 是兩點:

一是設備類型: 空中單位 (發射機) 是個接入節點和地面單位 (接收器) 是個中心節點.

二是下行鏈路和上行鏈路的速率比. 30公里以上, 最佳比率是 4:1 要么 3:2.

20. 當我插入接收器時會發生什麼 192.168.1.12 到現有路由器的 LAN 端口 10.220.20.1?

If you don't want to connect the receiver ethernet cable directly to the computer. 那麼在您的本地網絡上訪問接收器並不容易.

這裡有兩個解決方案給你.

1. 添加PC端192.168.1.x網段的IP地址 (PC可配置多個網段IP地址)

2. 修改無線視頻數據接收端的IP from 192.168.1.12 到10.220.20.x網段的地址，滿足你的本地網絡.

更多問題和解決方案, 請與您的局域網同事或工程師交談, 我們的接收器就像一台有 IP 地址的電腦, 它應該保持網段IP地址相同, 例如, 192.168.1.xxx.

21. 接收天線底座為大型磁力吸盤底座. 可以換成U型夾支架嗎?

是, 我們可以用U型夾支架來更換接收天線來代替磁力吸盤底座.

很容易固定在桿上. 磁性物品在運輸過程中需額外收費.

22. 如果我使用兩架無人機, 一個是發射器, 另一個是中繼器, 它們由一個接收器控制. TX900是否支援控制任務機和中繼無人機?

是, 有三種解決方案可以做到這一點.
TX900有3個資料端口. 透過不同的透明串口來區分, 例如D2控制中繼機，D3控制任務機. 缺點是TX900接收器需要連接兩個串列埠分別發送指令.
使用同一個透明串口批量發送數據, 然後添加層協議 (例如標題訊息) 來區分哪些飛機應該接收和處理數據. 缺點是發送和接收資料的處理複雜.
或使用兩個接收器: 一台接收器用於任務飛機 (發射機), 另一個接收器用於中繼無人機. 連接和操作更簡單.

還有一個問題?

客戶可設置工作帶寬為1.4M/3M/5M/10M/20MHz (但是1.4M/3MHz可能不適合視頻傳輸). 那麼TX900B-2W就可以工作在 跳頻模式 (跳頻擴頻) 中心工作頻率由系統自動選擇，可進行跳頻 (1420~1530MHz之間) 在其工作期間.
客戶也可以規劃使用1420~1530MHz全頻段，也可以設置設備工作在固定頻段.
TX900B-2W支持最遠距離22km.
除了支持的頻率範圍和最遠距離, 外表, 接口, 用戶界面, 手術, 等等, TX900B-2W 與現有的 TX900B-15km-2W 相同.
TX900B-2W僅支援頻率範圍為1420~1530MHz, 不支援800MHz和2.4GHz頻率範圍.
有兩個版本, TX900B-2W-15km, 和TX900B-2W-22km.
由於TX900B-2W頻率範圍是110Mb, 所以如果你配置工作頻寬為10Mb, 那麼你會得到 11 指向跳躍.
TX900B支援110Mb跳頻頻寬，只有三個傳輸範圍可選, 22千米, 55千米, 和 150 公里.
