1. Does motorola walkie talkie have radiation during using it?
In accordance with the regulations, the transmission power of the handheld walkie talkies should not exceed 5 watts. At present, no obvious harm has been found in the short-term use of walkie-talkies less than 5 watts. Short-term use means that the time of transmitting is less than 5%. For example, 24 hours a day, if you use it intermittently for an hour, there will be no problem.
2. How important is the walkie-talkie antenna?
Usually the longer the antenna is, the better the directivity and gain of reception and transmission will be. If you find it difficult to communicate, you can change it to a longer antenna. For longer antenna, you can switch to ordinary extended walkie-talkie antenna, or even folding ruler type antenna ranging from 80 to 108 centimeters long.
Generally speaking, the most important thing that affects the effectiveness of communication is occlusion. For example, your large antenna has a gain of 10 decibels and a tenfold increase in power, which would have been a hundredfold gain, but as long as there are several tall buildings in the middle, the gain will be offset. In the most extreme case, a large metal plate basically isolates the radio waves completely. Therefore, the height of the antenna is the most important, and the higher the antenna is, the less the barrier will be.
3. What price of walkie-talkie is more appropriate.
The circuit, antenna and sensitivity of the ham radios are almost the same. under the condition of the same path, the communication distance is mainly determined by power, therefore, the expensive walkie-talkie is not always much better than a cheap walkie-talkie. Whether it's $5 of inferior brand or nearly $1500 of Motorola's top-of-the-line walkie talkie, you'll find that their communication distances are basically the same. If you only need an underused spare emergency walkie-talkie, and you don't bump into it as often as commandos or police officers, you don't need to buy such an expensive walkie-talkie.
