A Closer Look at DSM2 Technology

摘要

The DSM2 protocol used by the DX8 and other Spektrum and JR full range systems utilize multiple receiver antennas to increase signal pathway diversity. Ideally, all receiver antennas will see a full strength transmitter signal at all times. However, in practice, some antennas may not receive the transmitter signal at all times if large metal or carbon fiber structures block or attenuate the transmitter signal. Installing the main receiver and remote receiver(s) away from large metal and carbon objects (motors, engines, pipes, batteries, wing tubes, etc.) will decrease the likelihood of signal loss. Placing the main receiver and remote receiver(s) in different parts of the aircraft with different antenna orientations will also reduce the probability of signal loss.
