We know that the antenna of the intercom is proportional to the transmission and reception of the walkie-talkie, and the antenna is a device that emits electromagnetic waves into the air. We usually use walkie-talkies in order to send more power into the air, so that when the other party receives the signal, there is still enough power to restore the content of the information. The antenna is an important component of the transmitting part. Today, let's discuss whether to choose a long antenna or a short antenna when buying a walkie-talkie?

In fact, the antenna of the intercom is not distinguished by the length of the antenna, but by the frequency band to distinguish. For handheld walkie-talkies, we can check the bottom of the antenna, there will generally be a mark, indicating that the antenna applies to the frequency range.

Greenhands to the "Ham" may feel that the longer the antenna, the more effective it is at transmitting or receiving signals. However, this is not the case. The antenna will only be as effective as the range that is most suitable for it. We know that there are a number of parameters that can affect the transmitting or receiving characteristics of an antenna, such as direction, weather, surroundings, quality, installation method, lifetime, noise and temperature. The length of the antenna is also a very important factor.

Finally, we want to discuss, for amateur radio enthusiasts, what length of radio antenna can achieve the best effect? Theory and practice have proved that when the length of the antenna is 1/4 of the wavelength of the radio signal, the transmission and reception conversion efficiency of the antenna is the highest. Therefore, the length of the antenna will depend on the frequency or wavelength of the transmitted and received signals.
