RB20 820MHz-845MHz/902MHz-928MHz Signal Relay is designed to work with radio controller to achieve the long range requirements. The RB20 ground unit could be connected to PC through a TTL-USB cable, to realize data transmission between PC and RB20 air unit, also could realize parameter tuning.
RB20 signal relay is suitable for DA16 radio controller. Just connect the RB20 ground unit to DA16 receiver, and the RB20 air unit to flight controller. RB20 signal relay can help to get a long communicate range, the max communicate range is 15-30km, and it depending on what kind of antenna are you going to use with this signal relay. Equipped with this RB20 signal relay and Foxtech 840-915MHz 7dBi magnetic base antenna DA16 radio controller can reach max range of 20km.
Note: RB20 signal relay is equipped with a TTL-USB conversion cable for USB connection requirment.
