The walkie-talkie products on the market are dazzling. Not only are there many brands, but the quality of the products is also uneven. Imported, domestic, high-end, low-end, dazzling products make people unable to start. The only thing that can be done is to follow the introduction of the sales staff. However, I still feel uneasy in my heart, how high the credibility is, I can't grasp it well, and I can tell you about the choice of some walkie-talkies for the multi-question of the brand in the brand of the walkie-talkie.
Introducing the six precautions for walkie-talkie purchase:
1, the classification of walkie-talkies
According to the type of communication terminal, the walkie-talkie can be divided into three types: hand-held walkie-talkie, car walkie-talkie (base station), and transfer station (relay station).
2. Frequency range.
Before selecting a walkie-talkie, you should first understand whether the walkie-talkie has a network access permit from the national radio administration. Secondly, we should understand the frequency of the work of the walkie-talkie. For example, the frequency range of the use of civilian walkie-talkies is 400~420Mhz.
3. Transmit power.
The transmit power is an important indicator of the walkie-talkie. It determines the talk distance, the use time and whether it will cause interference to other communication equipment. Therefore, when purchasing the walkie-talkie, you should know the transmit power of the walkie-talkie according to actual needs. The transmission power of the general civilian walkie-talkie is about 1W, and the launch power of the commercial walkie-talkie and professional walkie-talkie is about 4W. (The state stipulates that the transmitting power of the handheld radio must not exceed 5W).
4, call distance
Often the problem of the distance of the call is always involved when purchasing a walkie-talkie. In fact, the distance of the call is related to the transmission power of the walkie-talkie and the use environment or network conditions. The general communication distance within 2-3 km can be regarded as short-distance communication. For individual users, you can purchase a civilian walkie-talkie. For the unit user, you can purchase a small power walkie-talkie by applying. If you want to ensure the communication effect, you can choose a professional walkie-talkie. Need to communicate within the city, communication distance is within 3-10 km, you can consider buying a professional walkie-talkie. If it is farther away, it is better to use the base station to communicate with the handheld walkie-talkie, or the radio station and the radio station communication base station. We can use the car radio with a relatively large output power. If you need a longer distance or better communication quality, you can consider using a cluster walkie-talkie if you don't have a network. Because the radio intercom is supported by the radio network, the communication distance is relatively long, and the effective distance reaches 15-30KM. This type of walkie-talkie requires network support, so once it is disconnected from the network, just like the mobile phone is off the network, even if the two sides of the call face each other, they cannot call. .
5. The type and capacity of the battery.
The type and capacity of the walkie-talkie directly affects the use time and efficiency of the walkie-talkie. Therefore, pay attention to the type and capacity of the battery when purchasing the walkie-talkie. First of all, there are many nickel-hydrogen batteries and lithium batteries in the general market. Under the same volume, the nickel-hydrogen battery has high capacity and small memory effect. The use environment is: -30°C-60°C, the price is moderate, the self-discharge rate is high, about 25%, and the weight is heavier. The lithium battery has high energy density, large capacity under the same volume, and light weight, and basically has no memory. The use environment is: -10 ° C - 60 ° C, the self-discharge rate is about 6%, the price is more expensive than nickel-metal hydride batteries.
When purchasing the walkie-talkie, you should also pay attention to whether the battery is the original battery, and the marked battery capacity is sufficient. If there are conditions, you can use the instrument to perform a simple test on the battery to check whether the actual battery capacity matches the marked one.
6, warranty period and post-maintenance
At present, there are many walkie-talkie brands on the market, and the prices are high and low, and the difference is very big. However, before purchasing the walkie-talkie, it is necessary to ask the seller for the warranty and post-maintenance of the walkie-talkie, otherwise it will cause unnecessary trouble in the later stage.
    Regarding the brand of the walkie-talkie brand ranking, in fact, these are just for reference, the purchase method and the right one is the best!
    The above is the introduction of the content of the walkie-talkie brand ranking, I hope to help everyone.
