Catch the eye perhaps with a nationwide broadcast? (4-2)
I believe the answer is:
hook-up
'with a nationwide broadcast?' is the definition.
The definition suggests a singular noun which matches the answer.
'catch the eye' is the wordplay.
I cannot quite understand how this works, but
'catch' could be 'hook' (hook is a kind of catch) and 'hook' is present in the answer.
The remaining letters 'up' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for hook-up that I've seen before include "(Field) radio connection" , "Interconnection of broadcasting equipment" .)
