How to choose a walkie-talkie?
Practically every person in life hada situation where communication was required - on vacation in the forest or with a long drive by car. A cell phone does not always help, but the walkie-talkie will be an indispensable thing for such cases. In this article I will tell you about which radio. To date, the production of communication equipment does not stand still. New technologies are being used, digital methods of signal management and processing are being introduced - all this creates a wide range of radio communication capabilities. In Russia, more than 60 radio channels are allowed to be widely used. This causes a certain set of channels in many radio stations. If, for example, the tourist group decides which radio to buy for further use in the campaign, then they will need to choose one in which each member can be assigned a separate line, thanks to multi-channel.
What to consider when choosing a walkie-talkie
- The objectives of the acquisition - to ensure, for example, the connection of cars on the track should first determine the correct distance, this will help solve the issue of the range.
- Intensity of use - episodically, once from time, or permanently.
- Compliance with legislation in the field of communications.
When deciding how to choose a walkie-talkieremember that there is no ideal, or universal, radio station. Because for use on fishing or in the service of calling a taxi, radios will have a different range. It depends on the following factors:
- Frequency range
- Radio power
- Quality of the radio station
- Use in the car and radio base stations KSW (VSWR) antennas.
Radio stations for urban conditions
For example, for urban useyou should buy a walkie-talkie in a car base exactly the one whose power will not be affected by the density of the built-up area, and which will have the required range. A ready-made radio base station is not a profitable purchase, because it is very expensive and it is not designed to increase power. It is best to assemble the base station yourself from the following components:
- Car radios
- The amplifier (BUSTER)
- Power Supply
- Base Antenna
- Reduction cable
A walkie-talkie standing on a car should consist ofcar radio station and car antenna. There are many proposals for choosing an antenna for a walkie-talkie. Starting with the most simple and cheap "fishing rods" to the longest and most expensive. The main thing is to determine the power (400 - 600 W), with the gain (1.3-5.5 dB) and the installation, which can be with a magnetic base and a mortise. To put it simply, a longer length of the pin will provide a better connection.
In shops and markets that sell cellular phonescommunication, often there are "walky-talky" kits. They are inexpensive and easy to use. Such walkie-talkies are perfect for conducting negotiations at a short distance, for example, between a warehouse and a supermarket hall. But in more severe conditions these radio stations will not provide you with a quality connection, because are not provided with protection against external influences, such as humidity, dust, fall from height.
Builders, road services and housing offices, i.e. working in urban conditions, choose the preferred range that penetrates metal structures, brick and reinforced concrete. This range is from 400 MHz. For distances from half a kilometer, radio stations will be of low power, from such manufacturers as Midland, Icom, Vector. If the required distance of 3 km in the city, which is relevant for security companies or escorting cars around the city, then the radio is needed more powerful - Vertex, Kenwood, Icom, Motorola.
Radio stations for natural conditions
Buying a radio station for communication on the openAreas that are preferable for fishing, hunting or just relaxing in nature, it is best to choose a low-frequency range, from 140 MHz. They are allowed for amateur use. The wavelength of this range is best avoided by separately standing obstacles, in the form of hills, bushes, trees or pillars. Professional radios are of higher quality, from manufacturers such as Vertex, Kenwood, Turbo, Icom, Motorola, Roger, Midland, Linton, ViaRadio.
If you are going to conquer large waterwaysspace, then the VHF range is ideal. Radio stations operating on it will break through any obstacles not only in the form of forests and land, but also a large thickness of water. Morflot chooses this range for work. The radios working on it are distinguished by high moisture resistance, impact resistance and dustproofness. They can also be upgraded with a headset, which is useful both on vacation and at work. It will not be superfluous and a cover that will protect against possible unpleasant situations.
There are good options for radios that allowto communicate in the forest and in the city. This saves from buying two different sets. For example, manufacturers of the amateur radio Vertex FT-60R made it possible to work in both the lower and upper range, i.e. from 140 MHz to 433. If you suddenly decide to buy a walkie-talkie for hunting, but at the same time would like to use it in the city, this modification will suit you perfectly. If you find a malfunction in her work, if she worked fine yesterday at the dacha, and now she stopped at the supermarket, you just need to switch the range. Now you know everything about choosing a walkie-talkie. It can pick up a really necessary thing. We wish you a successful purchase!
