5.3 Steadyview Diversity Receiver

The M5F monitor utilizes a Steadyview Diversity Receiver, which combines signals from both antennas to provide a more stable and clear image, especially in challenging signal environments. This technology minimizes image tearing and rolling often seen with standard diversity receivers.
