How to choose the right means of communication for hunting
One of the most important indicators of radio for the conduct of the hunt can be called the greatest distance at which a transmission of information data from the transmitting device to the receiving. An important role in the work of the radio’s playing characteristics such as security of communication. For example, if the distance between the transmitter and the receiver is five kilometers, and the parameter of availability is 70 percent, good stability only in seven of the ten sessions. Another feature of the device is the location of the antenna height, and the higher the altitude, the less the ground absorbs the signal.
To enlarge the transmission distance of the signal, it is necessary to increase the transmitter power. No harm will increase the sensitivity of the receiving device. But in all this there is one caveat: increasing the receiver sensitivity does not always guarantee to increase the distance of the transmitted signal, due to the fact that the required signal is supplied to you in background noise, increasing sensitivity, you receive it limitations of the interference and noise. So, to fulfill the increasing distance of the signal transmission, it is necessary first to eliminate all kinds of noise and interference.
To increase the distance of the transmitted signal is used for various antenna feeder devices. The best option considered antenna with high gain in the communication session. You should also pay attention to the range of frequencies in which broadcast radio station, for example, broadcasting on the short waves is in the range of not more than 28 megahertz. The optimum frequency range at which you can easily obtain a permit for its use is considered 26-30 megahertz, but in large towns the relationship is not very good quality. Here you can use six-meter band (30 – 50 MHz).
The two-meter band (136 to 172 megahertz) provides the means of communication very good job and a steady reception and signal transmission on the hunt. However, it is necessary to take into consideration, to execute and to apply this frequency range, require large time costs associated with gathering all the necessary documents.
At six-foot range (from 136 to 172 MHz) radio for hunting is different based on smooth operation and stability of the connection. The range is very decent. However, for clearance to use the frequency you need to spend a lot of time and collect a large number of documents.
The most stable in their work, the frequency range is 70-centimeter band (420 – 473 megahertz). At this frequency, decent call quality, occurs even in underground tunnels and cities with high building density. In the last 5 – 10 years, due to increased competition and growth of the proposals, seen a General reduction in the cost of these devices.
Based on the fact that the law permitted the use of not more than 69 channels, companies produced communications only with their set. The multi-channel connection provides the advantages. For example, during a mass tourist event, each participant gets its own channel. For the most part, when buying a walkie talkie or other devices for communication are guided by the following criteria: weight and dimensional parameters of the device, the size of the channels for the power transmitting device, and of course, cost. Of course, you can buy a standard radio type, but large-scale collective hunts, it gives little rationale and benefits.
