Walkie-talkies are designed to transmit the voice of one person to another at a certain distance. In order to choose the right walkie-talkie, you need to have an idea of the power of the device, the frequency range and other parameters.
There are two main types of radio stations - professional and amateur. Amateur radios have a legal power rating and can be used without a special license. But to use professional walkie-talkies, you will need to obtain a certificate. You will also need to register the device.
How to choose a walkie-talkie, depending on the goals and operating conditions?
If you plan to use walkie-talkies in the woods, for a walk or fishing, hobby models are a good option. In such simple walkie-talkies, the settings can be changed manually, which is very convenient. For construction and installation work, professional radio stations with a wide frequency range, as well as protected from dust and moisture, are suitable. And drivers are better off choosing radios with a frequency range of 27 MHz. The range can be increased using a car antenna.
Within the same city, you can use radios with a UHF band. For normal operation in mountains or forests, walkie-talkies with a frequency range of 30-50 MHz are suitable. If the operating conditions are constantly changing, it is better to use tri-band handheld devices.
The main criteria for choosing radios
When choosing walkie-talkies, you should pay attention to such parameters as: frequency ranges, communication range, power and sensitivity. The shortwave range allows voice messages to be transmitted over long distances. These radios are usually suitable for marine applications. The CB range is intended for taxi drivers and car owners. Radios with LB range are especially good for use in rural areas. As for radios with the VHF band, they are widely used in rough terrain. If you plan to use walkie-talkies in the city, it is better to choose models with UHF range. They perform well in a densely built environment.
The radio communication range largely depends on the power and sensitivity of the device. The lower the sensitivity of the walkie-talkie, the better it works. This must be taken into account when choosing. And the ability to overcome electromagnetic interference depends on the power of the radio. In dense forest or rough terrain, increasing the power significantly improves the communication quality.
The most effective are radio stations with telescopic and car antennas. They have a long range.
