In some areas such as in the city with tall buildings, the range is only 1-2 km, or less. In order to have long-distance communication, we need a repeater. Standard repeaters have a high cost, and can be complicated to install, so there was a need for a simple and inexpensive repeater. The operation is very simple, and no power supply needed!
You do not need to change any part of the radio. All you need is just two handheld radios and connect the cables to the external mic/spk ports (2.5mm&3.5mm). You now have a very practical small repeater! 10 x the repeater with K Port. The transmission (and conventional repeater) of the different frequency, the A machine ACTS as the signal ascending receiver, and the B machine ACTS as the signal descending transmitter.To achieve the purpose of relay. Two-way forwarding, A machine receiver, B machine launch. When machine B receives, A machine launches. This feature enables two handheld intercom to become link relay! U- U, U-V are all available. Instructions for installation of repeater station antenna. No diplexer: when two handstands are connected to the relay station, such as a non-duplex, two antennae should be used separately. Two antennas should be erected vertically! And try to distance themselves from each other! Not less than 5 meters! In the case of a duplexer, the relay station only needs to connect a single antenna! And when setting up an aerial, there is no particular attention! Just as high as possible!
