CB radio, also known as band radio, is an amateur radio communications system, using two ways monocular transmitters operated on 36 channels in the lower frequency band, allowing handheld voice communication between people, using one way radios operated on 40 channels. These devices are commonly used by truck drivers along the route of the trucking companies. But its application was never limited to truck drivers alone. It has been used by various other classes of people including hikers, campers, hunters, hikers, postal workers, radio operators and others who communicate with others from remote locations. This has made a CB radio an international phenomenon.
It is interesting to note that this radio reached popularity very early, and despite its wide usage, the technology was implemented only after World War II. This may be due to the fact that the war resulted in millions of Allied soldiers being stranded and left behind. Many of them were not able to carry their personal radios and so they used a CB radio to keep in touch with their family, friends and other survivors. During this period, the use of this communication device by truck drivers and other military personnel was observed and this encouraged the manufacturing industry to come out with a product that could be used by different classes of people and fit all requirements and needs of such groups.
The radio spectrum of CB radio is divided into three categories according to its use. CB radio is the first to be used by government as well private users for communication purposes. All government organizations such as the Federal Aviation Administration (FAA), The Department of Transportation, National Forest Service and others use the same channel for their communication requirements. Private users on the other hand use the frequencies available through various license providers in various locations.
Most of the countries around the world have their own unique set of frequencies for the CB radio service and they operate and maintain these channels. The frequency allotted for a particular service provider is determined by taking into consideration factors such as the area that they cover and the population that they serve. It is very important that you have these frequencies unhampered and clear of any extraneous noise. Some of the factors that determine these frequencies include power lines, tall buildings and the weather. In addition, you will also come across other channels that are managed by the local governments for communications purposes.
There is no question about the fact that the CB radio is used widely by truck drivers and others who use the same channels for communications. However, there are also other users who do not use the frequencies allotted by the trucking companies. They can get these channels by accessing the Internet and using the software that is available online for download.
If you are interested in accessing these types of channels, you should use an antenna to listen to the transmissions coming from different sources. Such an antenna is known as the satellite dish and you will be able to enjoy the benefits of having a CB radio without using up airwaves that are allotted by the trucking companies. Other users of this type of radio service are people who are running businesses and need to communicate with their clients on a daily basis. You may want to use a hand held CB radio to keep you updated on what is happening at your place of business or in your neighborhood.
