Walkie Talkie Repeater Box for Handheld Two Way Radio Baofeng Wouxun Puxing Zastone - 0.09kg

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 frequency of most of the handheld walkie-talkies on the market is 400-470MHz, and the max output power is 5W.
This makes the effective talking range about 5-8KM(only in wide-open area).
In some areas such as in the city with tall buildings, the range is only 1-2 km, or less.
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).
