Soldier meets retiring girl, dish perhaps (7)
I believe the answer is:
antenna
'dish perhaps' is the definition.
(dish is a kind of antenna)
'soldier meets retiring girl' is the wordplay.
'soldier' becomes 'ant' (I've seen this before).
'meets' is a charade indicator (letters next to each other).
'retiring' says the letters should be written backwards.
'girl' becomes 'anne' (I've seen this before).
'anne' backwards is 'enna'.
'ant'+'enna'='ANTENNA'
(Other definitions for antenna that I've seen before include "Radio aerial" , "sensitive feeler" , "Insect's feeler" , "Insect's sensory appendage" , "Aerial - insect feeler" .)
