The amp Booster 5.8 GHz 2W Sunhans EsunRC SH-RC58G2W was developed specifically for applications in Radio Control, as the FPV (immersion in flight). The 5.8 GHz band is frequently used to transmit the video signal in FPV, the frequency of 5.8 GHz is very sensitive to obstacles, and the signal fades easily. This poses a problem because the FPV video link may be lost, which may cause loss of control of the model. Use of Booster will help increase the range significantly. The amp EsunRC SH-RC58G2W really designed for RC applications: 
 - Amplifier miniaturized
