✔ INDEPENDENT CHANNELS: Works in the frequency range of 2.405 to 2.475GHz.This band has been divided into 142 independent channels; each radio system uses 16 different channels and 160 different types of hopping algorithm<br><br>✔ MULTI DIRECTIONAL ANTENNA: This radio system uses a high gain and high quality multi directional antenna; it covers the whole frequency band. Associated with a high sensitivity receiver, this radio system guarantees a jamming free long range radio transmission. This radio system uses low power electronic components and sensitive receiver chip. The RF modulation uses intermittent signal thus reducing even more power consumption<br><br>✔ UNIQUE ID: Each transmitter has a unique ID, when binding with a receiver, the receiver saves that unique ID and can accepts only data from the unique transmitter. This avoids picking another transmitter signal and dramatically increases interference immunity and safety<br><br>✔ AUTOMATIC IDENTIFICATION AND MULTIPLE CHANNEL CODING: AFHDS2A system has the automatic identification function, which can switch automatically current mode between single-way communication mode and two-way communication mode according to the customer needs. And AFHDS2A has built-in multiple channel coding and error-correction, which improve the stability of the communication, reduce the error ratio and extend the reliable transmission distance<br><br><strong>✔ FS-i6 TRANSMITTER SPECIFICATIONS:</strong><br>   1.
