Perhaps dish first artist taking risks (9)
I believe the answer is:
aerialist
'artist taking risks' is the definition.
(acrobat performing high above the ground)
'perhaps dish first' is the wordplay.
'perhaps dish' becomes 'aerial' (satellite dish]).
'first' becomes 'ist' (ist resembles 1st).
'aerial'+'ist'='AERIALIST'
(Other definitions for aerialist that I've seen before include "skier" , "Trapeze acrobat" , "Highly-regarded performer" , "trapeze artist" .)
