۳DR Wireless Data Transmission/Radio 433M/915M 100mW RX+TX Telemetry w/OTG for APM2.6 2.8 Pixhawk FPV system Antenna F19607/8 This item is adding Amplifier on the hardware, No changing on software.
So that in the software will be showed as the previous ۲۰DB ۱۰۰MW ,
but actually The output will reach ۱۰۰MW.
(۴۳۳MHZ and 915MHZ is optional , If you have request about it, Please feel free to message us)
