If it's just FM the owner wants then perhaps consider a 300Ohm Balanced Feeder 'T' Ariel, assuming the Tuner has a 300 Ohm i/p. ? Most tuners will accept a T aerial (2 little screw/spade connectors usually) and if not a Balun transformer will convert a 300Ohm T type to a 75Ohm coax albeit at a slight loss due to transformer core and winding losses. I don't know if Cable/Sky type installations carry FM signals over the same cable, I wouldn't have thought so TBH.
Having said that, a cable box might have a 75ohm FM aerial outlet to feed your tuner if those cables are connected to a communal Satellite/ Cable system.
