'cable' is the definition.
(I know that coax is a type of cable)

'company needing a vote in support' is the wordplay.
'company' becomes 'co' (abbreviation).
'needing' is a charade indicator (letters next to each other).
'vote in' becomes 'x' (how votes are marked. I am not sure about the 'in' bit.).
'support' is a charade indicator (letters next to each other) (in a down clue, some letters hold others up).
'co'+'a'+'x'='COAX'
