How to solve the power problem for the radio communication repeater

Many industries choose radio to solve daily communication problems, such as security, church, school, transportation, etc. Radio brings great convenience to our life and work, but it is well known that the communication distance of radio is limited. In order to expand the communication distance, We usually use repeaters. The use of repeaters can double the communication distance of the radio.General repeater are mainly charged by direct charging, which is suitable for places where power is convenient. However, when we are in an environment without electricity, such as outdoor, remote mountainous areas, or temporary projects, how to solve the problem of relay power supply? ? Taking the Retevis RT97 repeater as an example, here we share three methods solve the power problem for the radio communication repeater:

1.Car charging method:

This method is suitable for the situation with a car. At present, the car cigarette lighter is one of the most basic configurations of the vehicle. Basically, all vehicles have a configuration. The cigarette lighter power supply for household vehicles is generally 12V DC, which can meet the repeater power supply. This method is very convenient and it is easy to solve the problem. All we need to prepare is a car charging line. By the way, Retevis RT97 The original packaging contains the car charging cable.

2.Portable power source:

Outdoor activities and temporary activities usually require a simple and easy-to-carry power supply to work as a repeater to solve the communication distance problem of the radio. Because of its small size, easy portability, and greater safety, portable power source is obviously the best choice. For example, Retevis RT97 operating voltage  is DC12-24v,if we choose to provide a 12V 20AH power supply, you can use 20AH / 2.4A = 8.3 hours continuously.If need longer, we can choose a device with a larger capacity.

3.Solar battery powered:

Because solar energy can be used free of charge, there is no need for transportation, no pollution to the environment, no geographical restrictions, short construction period, random scale, easy disassembly and assembly, convenient movement and other advantages,This method is widely used in forests, roads, rivers, mountains and other radio communication systems.Share the topology of Retevis RT97 repeater using solar power supply is as follows (from Rolly June Roda, Philippines):

As the widely use of radio, there will be more and more solutions to solve the problems faced by radio communications. If you have any ideas or suggestions, please feel free to contact us.
