The RB20 902MHz-928MHz Signal Relay is designed to enhance the long-range capabilities of a radio controller system. It consists of a ground unit and an air unit, which work together to achieve extended communication range. The ground unit can be connected to a PC using a TTL-USB cable, allowing data transmission between the PC and the RB20 air unit and enabling parameter tuning.
The RB20 signal relay is specifically designed for use with the DA16S+ radio controller. To utilize it, you need to connect the RB20 ground unit to the DA16S+ receiver and the RB20 air unit to the flight controller. By employing the RB20 signal relay, you can significantly increase the communication range. The maximum range achievable is stated to be between 15-30km, depending on the type of antenna used in conjunction with the signal relay.
For optimal performance, it is recommended to pair the RB20 signal relay with the Foxtech 840-915MHz 7dBi magnetic base antenna. When the DA16S+ radio controller is equipped with this RB20 signal relay and the specified antenna, it can achieve a maximum range of 20km.
Note: RB20 signal relay is equipped with a TTL-USB conversion cable for USB connection requirment.
