You can connect the wire of the coax cable to one of the sockets of the FM-antenna connector and the shield of the coax cable to the chassis (marked ground or earth).
Though the FM-aerial connection on your radio is symetrical 300 Ohms, the coil behind the socket is tapped in the middle and connected to the chassis. Between one of the sockets and the chassis the impedance is about right for a 75 Ohms coax connection.Because cable distribution systems don't support AM signals for SW, MW and LW you have to use the internal ferroceptor for MW and LW. For SW you'll need a long wire antenna.
The long wire antenna can also be used for LW and MW.Regards,
