- The radio repeater
To increase the capacity of the station supplied to an external antenna, use the radio repeater. The amplifier allows you to improve the quality of the signal without introducing distortion in its structure.
The radio repeater changes the characteristics of the hardware only when the device is operating in the transmit mode. On the reception signal from the other respondents the use of the amplifier is not affected. Some manufacturers build in amplifiers circuits, and amplifying the received signal, but with the amplification of the useful signal in this case also increase noise.
When you connect the amplifier insert it into the gap of the antenna cable, between radio and external antenna. Connect the thick wires to the amplifier power supply. If the amplifier is placed on the car station wire connect to the "positive" terminal of the battery, protecting it near the fuse terminals. The "minus" wire pick up the same diameter and minimum length.
A large cross section of the wires is required to provide a possible "drawdown" of the voltage in the wires of the power supply, because the amplifier consumes while transmitting a very high current. Short negative wire to limit the impact of resonance in power circuits. This wire must be securely fastened, as its breakage can sometimes lead to equipment failure.
Well adjust the antenna connected to the amplifier, and keep it in order. Pressing shift on the negotiating device when the antenna is disconnected or damaged cable can cause damage to the amplifier.
Advice 2 : How to increase the range of radio
Radios are popular with truckers and security guards, as people in these professions need to constantly communicate between themselves. The use in such cases, mobile communication is not advisable due to the high cost of minute of conversation. Using modern walkie talkies, you can talk to each other without interruption an unlimited amount of time.
Most radios from leading manufacturers have a range of about a kilometer, which allows for the protection of any object the guards talk among themselves. Sooner or later every person using the radio, there is a desire to increase the range of its validity. There are several ways to realize this desire.For example, if you want to increase the range of the radio, replace the conventional helical antenna is a special four wave pin, which you can buy in almost every market.
Can also be used as an antenna a long piece of coaxial cable, which can significantly amplify the signal. Configure the frequency of the radio so that it would send a signal as far as possible.
The range of the antenna depends on the output power path. Choose the optimum frequency for signal transmission, remembering that the closer to the edges of the working range is significantly deteriorated many of the characteristics of the radio for truckers, such as sensitivity and power. Therefore, standard antenna tuned to the middle frequency range. That is, if your radio transmits a signal in the range of 136-174 MHz, then the highest range it will show, at a frequency of 155 MHz.
Always use a well charged battery, as the power output depends on nutrition. Therefore, if you are going to use the radio for a long time, always carry a spare battery. Also, if necessary, increase the transmission distance of signal of your walkie talkie brand midland for a communication session, use the hills on the terrain.
A good radio will allow you to communicate with your colleague at work and in the event of an emergency, quickly come to his aid. At the moment the most popular manufacturers radios are Midland and Motorola. Each of these companies provides a wide range of various digital and electronic products from conventional radios to all stations.
