We call it a hand table because there is also a car table. You're right. Speaker should refer to the console, right? I used Mo Haiwei's. It's been many years, and nothing is broken. Only a few batteries have been replaced in dozens of models. If you want to buy a mobile phone, you need to find something simple. Our only function is walkie-talkie. I also have a public mobile phone, which is of little use. I hardly need it. The signal of driving to remote areas such as Inner Mongolia, Xinjiang, Tibet and Qinghai is not very stable. Some have mobile signals, some have Unicom signals, which can't be used in tunnels, so we still choose the simulator. I have no problem with 5 kilometers, the call is clear and my skin is tough. For your own use, you can consider buying a big brand. We are a road bus, so the merchant promised to take this brand back to 300 yuan for repair if it is broken.
After that, there may be ham to give you a detailed introduction to the popular science knowledge about walkie-talkies. What I want to tell you is that the higher the power of the car radio, the better. 50w, hand-held UV dual section, feeder and antenna should not be cheap. Hand-held radio, the same hand-held frequency UV two-stage, 5w is enough, imported ones are not more than 5w. Many domestic names 8w 10w are basically empty labels, even if they are true, they are harmful to health. Foreigners are not stupid. There must be a reason why they don't power up! Hehe, brand: imported Bazhou Motorola, domestic Baofeng Shengsheng, and domestic products with the same parameters are expensive. In fact, if you look for a car owner with a bg6*** brand on his ass, they will teach you enthusiastically!
Let's talk about the brand first. It turns out that my friend and I have a self-driving club. Because of the geographical characteristics, I often visit go on road trip, Gansu, Qinghai, Xinjiang and Tibet. Of course, many of them are amateurs. As for walkie-talkies, our standard is made by Motorola in Bazhou. Because it requires good quality, waterproof and anti-falling, and also prevents tourists from randomly adjusting the frequency band, all of them have simple functions, built-in frequency band adjustment, and some of them bring their own walkie-talkies to facilitate social interaction. Later, many tourists often took part in all kinds of self-driving, so I also had some experience in recommending walkie-talkies here. I don't talk about professional photos here, just ordinary users who are suitable for driving. According to the customer's reaction and actual use, it is more convenient to hold a desk. Domestic brands mainly recommend Beifeng and Firebird, which are cheap, professional manufacturers, with real power, uncomplicated functions and good sound quality. The frequency of use can be input by themselves, which is convenient for tourists and various walkie-talkies. Basically, it is 3w, and many brands are nominally above 5w, but in fact, the civilian ones are definitely not up to it. In the west, there are few self-driving mountains, good air quality and less radio interference. This kind of walkie-talkie is enough. In terms of distance, the dispersion of the team generally does not exceed 5 kilometers. For customers with higher requirements, we usually add a seedling for tourists, generally using a suspended ceiling. Moreover, the management is still very strict when installing a fixed and car-mounted platform in road trip, especially when going to some bases and military scenic spots, it is absolutely impossible to go without a license, so a low-power hand platform is still the first choice. In addition, some tourists have higher requirements for self-driving. We usually buy or recommend imports through the internet, mainly Motorola, but now Jianwu is not recommended, as well as HiWiLi, Yaekju and so on. But try to recommend the police money, the disadvantage is big. In fact, the domestic civil models are not bad, and the cost performance is also high. In addition, it must be equipped with a handheld microphone to facilitate driving.
Although the off-road vehicle is going to rain, mountains and other places, it is recommended that you use the hand platform, because the off-road vehicle will not be too far away. Generally, as long as the team organizer has a bus relay.
In fact, users really don't care too much about the power label. It is enough for ordinary people to go out and play with 3w. Many people say that the power must be high, but it is rarely used in actual use. In many cases, adding seedlings is enough, and it is also convenient to carry when you get off the bus. In addition, relying on the experience of organizing go on the road, it is reasonable to suggest that each car be equipped with two sets, of course, it is best to have one set for one person. The distance you asked is 3-5 kilometers in the open area and 2-3 kilometers in the urban and mountainous areas. It will be much better if seedlings are added. But to say tens of kilometers, it must depend on the bus relay and the height of your station. Now there are many car platforms, selling relay prices, which are actually simple car platforms. I've seen more than one gullible customer. In fact, Xiaomi's mobile phone is good now Recently, I have seen many people using it, and I can change the antenna and add seedlings. The sound quality is good.
By organizing activities, we actually see that many people pursue so-called professionalism and high-end, but they don't need it at all. Many places we go to have cell phone signals, but even if there is no data signal, most of them have voice signals, including organizations that crossed Hoh Xil that year. There are not only voice signals, but also domestic mobile phones can really hit more than ten kilometers because of good air quality, less electromagnetic interference and flat mobile phone signals. But there are some special places where the interference is so strong that the mobile phone can't be turned on at all. It's all interference to turn on the phone. We will tell tourists in advance in these places, and some sections are determined not to open mobile phones.
From Gansu to Qinghai, we met many professional radio enthusiasts and motorcades. I once made a phone call from Longnan, Gansu Province to Qarhan, Qinghai Province by using the 3w handstand of the north wind in 200 yuan, which was a high-power relay used by enthusiasts. So when you say long distance, it's all because of the professional fixed relay base station. So there is a professional bus relay in the team, so don't worry too much.
Whether the walkie-talkie is easy to use does not depend on which brand. If the distance is long and the call is clear, it depends on the relay station. Its height is high enough, because the signal of the walkie-talkie is straight-line communication. As long as the relay station is erected on the mountain or high enough, the walkie-talkie can be guaranteed to be easy to use, far away and clear.
In addition to the relay station, other accessories, power, is also very important, including the greater the power of the relay station, the stronger the signal, the walkie-talkie itself has power, generally 5w, and some walkie-talkies are10 W. The greater the power, the higher the transmitted signal strength in theory, and there is no obstacle, so the signal will be stronger. Of course, there is an antenna. A good antenna can also be enhanced.
Usually on the road, we will see many car radios with external antennas. Do you know why? In fact, car radios or hand-held radios are equipped with external antennas, so the signals will pass up the stairs, because there will be glass and iron plates in the car, and these signals will be blocked. Most importantly, these signals will be reflected back and radiated to the human body, which is extremely great.
Finally, add one more point. In theory, you need to go to the radio management department, report to the examination and approval department for the record, and get the use certificate before you can use it. Otherwise, it is illegal to use it, but it is not fun. In this regard, which donkey friend has this experience, you can share it …
All right, that's it! If you have any other questions about outdoor driving, you can always pay attention to the official WeChat account and go to road trip, a Tibetan area. Reply to the key words and you will have a series of common sense about driving in Tibet. Finally, I wish you happiness.
The communication distance of walkie-talkie mainly depends on the transmitting power of equipment. Generally, the hand platform is 2-5 watts, and the car platform 10-50 watts. The advantage of the hand platform is that it can walk with people and is convenient. The disadvantage is that the communication distance is short, generally 2-5 kilometers, which requires constant charging. The advantage of the car platform is that the communication distance is long, 10-50 kilometers, and no charging is needed. The disadvantage is that you can't talk to people.
Of course, foreign radio equipment manufacturers are more famous than domestic manufacturers, but foreign equipment is more expensive. Domestic equipment started from imitation, which is very humanized. For example, the foreign frame type is not equipped with speakers and connecting wires, so you need to buy back the frame type and then buy speakers and connecting wires; The random host and receiver of domestic automobile platforms have their own speakers and do not need to be purchased separately. As for the brand, it is not recommended. Choose it yourself.
Distance has nothing to do with brand, but with mode, installation and performance:
1, analog and ordinary digital walkie-talkies, depending on the power, the higher the power, the farther it goes.
2, the antenna is installed outside the car, and the distance is farther, which is better than the handheld radio and antenna installed in the car.
3, mobile phone signal walkie-talkie, generally China Telecom, can be used in the range of mobile phone signals, in theory, all over the world, but the stability is poor.
4. Digital trunking walkie-talkie is generally used by police and airports, depending on the coverage of base stations.
One is for civil use. Depending on the power, it is 5 watts on the hand desk and 5-50 watts on the car. Team, use the car to carry the platform.
Brand differences: stability, sound clarity and durability. be good value
There are various brands of walkie-talkies, and there are many small factories in Quanzhou, but the quality is excellent. Hainengda and Quansheng recommended in China are barely enough. The imported Motorola is responsible for the quality, and Bazhong, Jianwu and ICOM are also famous.
Commonly used walkie-talkies are divided into vehicle-mounted (generally called vehicle-mounted platform) and handheld (generally called handheld platform) in form, and divided into U-segment, V-segment and short wave in wavelength. The walkie-talkies we often talk about are generally U-shaped and V-shaped walkie-talkies, and the power of car walkie-talkies is generally between 5W and 50W. Generally, the power of hand-held walkie-talkies is between 0.5W and 5W, and the handsets with the standard above 5W on the market are all virtual labels, which can't be achieved at all. Generally speaking, the communication distance of walkie-talkie depends on several main factors: power, antenna, environment and altitude, among which environment and altitude have the greatest influence. If the communication environment is good and the height is good, the communication distance of the 0.5W handheld platform can exceed 5 kilometers, and the communication distance of the 5W vehicle-mounted platform can reach tens of kilometers. If the environment is disturbed, and it is in the jungle or urban buildings, even if the power is adjusted to the maximum, it may not reach several hundred meters. I tested it with local ham. In urban buildings, 25W communication can reach as far as 3 kilometers. We all use Hainengda MD780, and it is unrealistic to talk about communication distance only by brand, so we can only guarantee reliability under the same conditions.
It is suggested that if off-road vehicles often cross, it is best to install platforms, and brand selection suggests Bazhong Zhou, Jianwu and Hainengda. The quality of these brands is guaranteed and the platform is powerful. In addition, without the shielding of the car body, the communication distance will be much better.
It doesn't matter if you go out to play occasionally. You can load the platform or bring a handheld platform. Handheld platform is convenient and flexible. Can be equipped with car charging, and can be carried with you after getting off the bus. Brand, there are many kinds of walkie-talkies of the above brands, which can be selected according to their own economic conditions and actual needs.
In addition, there are a large number of network walkie-talkies in China. This kind of walkie-talkie is connected to the internet, and the communication distance is not limited. As long as there is a telecommunication signal, it can communicate, and the communication effect is very good. If you don't go to no man's land, it's also a good choice.
Finally, if conditions permit, it's best to get all the platforms ready just in case. I hope my answer can help you.
Motorola is certainly the best. If it is too expensive, buy the economical Quansheng UV2Plus. Ten watts of power is not bad.
Domestic well-informed, spring-filled, and Eurovision 5W machines can basically meet daily use. If the money is not bad, you can buy Motorola, Jianwu and Bazhou. No matter what brand of simulator, it will be affected by environmental factors such as topography and electromagnetic field. It is good to shout out two kilometers with a 5W machine in mountainous areas, and hundreds of kilometers with a 1W machine at sea. Improving the transmitting power is not as good as improving the receiving sensitivity. Try to use the same or similar frequency as the antenna center frequency (be careful not to interfere with other people's communication). In addition, it is suggested to set up a mobile relay in the middle of the motorcade to double the communication distance of the hand station.
