Long-range radios include radio equipment, which provides communication at a distance 10-20 km and more. This range is possible with a powerful transmitter., sensitive receiver, high signal quality, which is transmitted over long distances without loss.
Where are amateur and professional long-range radios used?
Many frequencies, used for both, and for long-distance communication, are civil, but some are reserved for office use, professional purposes:
- for the needs of the army;
- to ensure security at the state level;
- in civil aviation;
- for emergency response services - police, ambulance.
Frequency ranges are allocated for professional long-distance radio communication, where the best signal quality is ensured. A number of free frequencies can be used by civilians, long-range walkie-talkies actively use:
- tourists, climbers for communication between group members in the absence of mobile coverage, search for stragglers, lost;
- hunters to exchange information;
- travelers;
- employees of private security firms.
But truckers are in demand for long-range car radios. The size of the coverage area depends not only on the characteristics of the radio equipment itself, but also from the antenna. You can increase the range of the walkie talkie, using a replaceable antenna with a longer rod length, the same applies to car antennas.
Long-range mobile and stationary radios
Long-range radios are subdivided into:
- portable, small in size and designed to be carried;
- mobile, more overall, for installation on transport, equipped with a remote antenna;
- stationary radios (base radio stations), installed indoors, can operate exclusively on dedicated frequencies. Used to communicate with wearable and mobile radios, usually in conjunction with a repeater to expand the coverage area.
Japanese manufacturer Kenwood produces walkie-talkies for both, and for long-distance communication. So, many models of the TC line provide communication at a distance 15 km, are designed for use in extreme conditions, do not require a license. You can buy long-range radios, working in digital and analog mode.
