Stubbly, perhaps: shaved for broadcast (3)

I believe the answer is:
air
This clue might be a double definition.
'stubbly perhaps shaved for' is the first definition.
The definition suggests a singular noun which matches the answer.
'broadcast' is the second definition.
(to air on TV)
Can you help me to learn more?
(Other definitions for air that I've seen before include "Atmosphere surrounding us" , "Broadcast; mien" , "'Tune, melody (3)'" , "voice giving > impression" , "Ventilate a tune?" .)
