That circuit relies heavily on using a period long wire(outdoor) antenna along with a good(Short)earth ground at the chassis. Now days folks tend to think of the antenna as a few feet of wire strung indoors and letting the ground float. Of course the signal cant' go to zero if there's a good portion of rf riding on the chassis ground reference. In some situations it's possible to have more rf on the ground than at the antenna. Even the wire between your chassis and earth ground acts as an antenna to the rf signal.
