1995 yamaha reciever?

The coaxial cable input seems to be a larger size than modern cable. Had an adapter, but is no longer working. Don't know what to call it to find replacement. Any ideas? Can't hook up cable for FM radio.

Most stereo receivers have a standard "F" fitting for coax input to the FM radio. If it is something else, then it is truely odd. What is the model number?
