Accessories and parts -FS-i6S Transmitter FS-iA6b Receiver for Drone Quadcopter Highlights generic brand FS-i6S Transmitter FS-iA6b Receiver for Drone Quadcopter Description: 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 kinds of hopping algorithms. Film selection on the transmitter for easy handling! This radio system uses high gain and high quality multi-directional antenna, it covers the whole frequency band. Combined with a high-sensitivity receiver, this radio system guarantees long-range radio transmission without interference. Each transmitter has a unique identifier. When linked to a receiver, the receiver retains this unique identification and only accepts data from the unique transmitter. This avoids choosing another transmitter signal and greatly increases interference immunity and safety. This radio system uses low power electronic components and a sensitive receiver chip. RF modulation uses an intermittent signal thus further reducing power consumption The AFHDS2A system has the automatic identification function, which can automatically switch from one-way communication mode to two-way communication mode according to the customer's needs, Built-in multi-channel coding and error correction, which improves communication stability, reduce error rate and extend reliable transmission distance Specification: Transmitter Specification: Channel: 10 Channel Resolution: 4096 steps Low Voltage Warning: less than 4.2v Battery: 6v 1.5 AA x 4 (not included) Certificate: CE, FCC RF Specification: RF Range: 2.405 - 2.475GHz Bandwidth: 500khz RF Power: less than 20dBm RF Mode: AFHDS 2A Modulation Type: GFSK RX Sensitivity: -105dBm Receiver Specification: Channel: 6 Model Type: Fixed Wing/Helicopter/Glider RF Receiver Sensitivity: -105dBm Modulation: GFSK System Type: AFHDS2A/AFHDS Channel Resolution: 1024 steps Bind port: yes Power port: yes (VDC) Power: 4V -6.5V DC Certificate: CE, FCC Size chart: Size: approx. 18 x 16 x 4.5cm / 7.09 x 6.30 x 1.77inch Antenna Length: Approx. 26mm / 1.02inch Package includes: 1 piece FS-i6S transmitter 1 piece FS-iA6b receiver 1 piece manual
