I have always had adequate reception on both the AM and SW bands using just the internal antenna. I suppose, if you want, you can hook an external long wire to the left most terminal, and leave the regular antenna also connected.  The picture below clearly shows how the internal antenna as well as the original FM antenna connect to the back of the set.
