The feed quality drops in a way that makes the shaking antennae explanation seem plausible. I doubt the announcers knew then (why not just say so unless there was some ambiguity?), but it must have been a distinct concern, hence their 'smile nervously' reaction.

It is a bit odd they haven't announced that it was lost yet, but I agree that seems very likely.

FWIW the drone ship feed has been lost in exactly the same way every time I’ve watched a landing.

I can concur. There’s always 5-10 seconds starting right as the exhaust enters the frame when it cuts. IIRC they have one or two satellite uplinks and they go down due to the vibration.

Also in the video if you watch mission control’s wall of monitors you can see the feed cut back with an empty drone ship a minute or so later. Seems to confirm that the rocket missed the deck due to the engines not lighting.
