Like on this video, on the top left, around 1:10 it shows when a signal went off and the other has strength.  Rather than have no idea when you go to a grey screen to a blackout RTH, it would be cool to have a diversity like this so we know it's time to switch frequencies or auto does it by itself but we can at least see 2 antennas and it's strength.

Hi, thanks for sharing this idea. This would be forwarded to our designated department for attention. Thank you for your support.
