FAQ：
1. Is the antenna standing wave guaranteed to be less than 1.5?
The antenna has been strictly tested by comprehensive testing instruments before leaving the factory, and the standing wave within the applicable frequency range of the antenna meets the technical parameters provided by the manufacturer (less than 1.5). However, because the antenna standing wave test result is affected by many factors such as test frequency, antenna installation method and installation location, feeder, test equipment, etc., we cannot guarantee that the standing wave in your test environment is less than 1.5. Generally speaking, with standing waves below 2.0, it can be used normally. If the standing wave test of the antenna you purchased is too high, please contact customer service in time, we are happy to analyze and solve it for you.
2. What is the withstand power of the antenna?
The withstand power of an antenna represents the maximum power that the antenna can withstand, and is related to the material and physical dimensions of the antenna, such as the diameter of the resonant coil and the thickness of the vibrator. When choosing an antenna, please make sure that the transmitting power of the radio does not exceed the withstand power of the antenna to avoid damage to the antenna. Car mobile walkie talkie needs to be used with an external car antenna, and your radio's low power can drive the car antenna.
3. Buy a long antenna or a short antenna?
For the amateur antenna products currently on the market, the length of the antenna is usually proportional to the antenna effect, and the effect of a long antenna is usually better than that of a short antenna. Generally speaking, for two antennas with a difference of 5 or 6cm, the difference in effect due to the length is not obvious, and the difference in effect caused by structural design is more important. However, for two antennas with a difference of 10 cm and 20 cm, the effect difference between them has a relatively large relationship with the length, which can not be solved by simply relying on structural design. If you use the 144MHz frequency band, it is recommended to choose an antenna with a length of 70cm or more, the effect will be better.
