High Quality This radio system uses low power electronic components and a very sentive receiver chip.AFHDS2A has bulit-in multiple channel coding and error-correction,which improve the stability of the communication,reduce the error ratio and extend the reliable transmission disstance. Avoid Interruptions Effectively The frequency range of AFHDS2A is from 2.405-2.475GHZ,The whole band is divided into 141 frequency points.Each system with unique frequency hopping rules uses 16 different frequency points,which can avoid interruptions effectively. Unique ID Each transmitter has unique ID.When binding with the receiver,the receiver saves the unique ID and can accepts only data from that unique transmitter.This avoid picking another transmitter signal and dramatically increases interference immunity and safety. High Gain Antenna This radio system uses a high gain and high quality multi direction antenna.It covers the whole frequency band.Associated with a high sensitivity receiver,the system can ensure a jamming free radio transmission. Specifications: Stylish design and precise operation. 70° rotation,hand wheel is easy to operate. The transmitter handle is with good workmanship and does not slip, making it easy to hold.
