Professional analog VHF radio systems — for what, the pros and cons of using

By CrimeaNEWS On Июл 18, 2023

CrimeaPRESS reports:

VHF (Very Short Wave) professional analog radio systems are radio systems that use analog signals to transmit voice and other information. These systems are widely used in various fields where reliable and fast communication over short distances is required.

Application of analog VHF radio communication systems

What do you need to know about professional analog VHF radio communication systems in order to put them «in operation»? It is probably worth starting with the fact that such a technique is in great demand. Moreover, it is in demand by specialists of a very high level. So, VHF communication use:

operational services: almost all specialized organizations and services, such as law enforcement, firefighters, ambulance, security services, construction crews, use analog radios for operational communication between personnel on the job site or in emergency situations.
industry and transportation: manufacturing plants, ports, airports, railways and other industries can also use analog radio communication systems for communication between workers, coordination of actions and security on the territory of the enterprise.
sports and mass events: organizers of sports competitions, festivals, concerts and other public events can use radio communications to communicate with employees and ensure safety at the event.

The main advantages of analog radio communication systems:

Ease of Use: Analog radios are usually easy to use and do not require complicated configuration.
Reliability: Relatively reliable and stable in limited radio coverage over short distances.
More affordable: In some cases, analog radio systems may be less expensive than digital systems.

The main disadvantages of analog radio communication systems:

less security: when using analog systems, signals can be subject to interference and interception, which can reduce the level of confidentiality and information security.
Less efficient use of frequencies: Analog systems use more RF resources than digital systems, which can limit the number of simultaneous communication channels.
Limited features: Analog systems may provide fewer data transfer options and additional features that are available on digital systems.

At present, digital radio systems such as DMR (Digital Mobile Radio), P25 (Project 25) and Tetra (Terrestrial Trunked Radio) are becoming more and more popular in professional fields due to their advantages in frequency efficiency, security and transmission capabilities. data. However, analogue radio systems still find their use in certain areas, especially where ease of use and reliability (!) over short distances are required.

Selection Criteria for Professional Analog VHF Radio Communication Systems

And the criteria for choosing professional analog radio communication systems at ultrashort waves should be taken into account when choosing devices! They help determine the most appropriate system for specific needs and conditions of use. In particular, we are talking about:

communication range. Estimate the required communication range for your application. Different radios may have different transmit power levels, antenna systems, and operating conditions.
number of channels. Make sure the system you choose supports enough channels to allow communication between all users in your group or organization.
waterproof and dust resistant. If radio communications are required in damp or dusty environments (such as a construction site), select radios with appropriate waterproof and dustproof standards.
battery and operating time. Pay attention to the type of battery and its capacity. It is important that the radio station operates long enough to cover the period of operation or event.
additional functions. Some radio systems may have additional features such as noise suppression, channel scanning, vibration alerts, and others that may be useful in your particular application.
licensing. Find out if a license is required to use selected radios in your area. Some VHF systems may be licensed, which may affect their cost and terms of use.

When it comes to purchasing professional analog VHF radio systems, specialist shops and dealers are the only right place to buy. These companies and shops usually offer a wide range of different models and brands, and can also provide professional advice on choosing the best system based on your needs and budget. Specialists can also help with setting up and maintaining the radio system.

So, for example, TISSCOM LLC performs a full range of works on the design of a radio communication system.

In particular, this is the design of antenna-feeder equipment and antenna supports; obtaining permits for the use of radio frequencies; calculation of radio coverage zones using specialized software, taking into account the nature of the terrain, the presence of natural (forests, hills, ravines, etc.) and created obstacles (buildings, structures, etc.). We provide delivery of VHF communication equipment kits, installation and commissioning of your company’s radio communication system, including all types of post-warranty service, repair and technical support— experts of the company note.
