Station in Stronaba sector (4)
I believe the answer is:
base
'station' is the definition.
(synonyms)
'in stronaba sector' is the wordplay.
'in' indicates the answer is hidden within the clue.
'BASE' is hidden in the letters of 'stronaba sector'.
(Other definitions for base that I've seen before include "Meanspirited" , "Pedestal" , "Ignoble; bottom" , "Reprobate" , "Bottom; vile" .)
