Without cover, nudes ruin broadcast (9)

Ross

I believe the answer is:

uninsured

I'm a little stuck... Click here to teach me more about this clue!

'without cover' is the definition.
I can't judge whether this defines the answer.

'nudes ruin broadcast' is the wordplay.
'broadcast' indicates an anagram.
'nudes'+'ruin'='nudesruin'
'nudesruin' with letters rearranged gives 'UNINSURED'.

Can you help me to learn more?

(Other definitions for uninsured that I've seen before include "with no policies" , "Not covered against loss" , "Not covered for losses" , "Being without cover" .)

I've seen this clue in The Guardian.
