Yamaha T-80 tuner FM connector type?

I bought a used Yamaha T-80 tuner. The tuner has a 75 ohms unbalanced connector for connecting to an FM antenna. I have an FM antenna that has an F-type connector (coax like), which does not seem work with the T-80's 75 ohms unbalanced connector. Does anyone know what the T-80's ohms unbalanced connector is called? Any convertor that I can use to connect the F-type connector to the T-80? Thanks!
