That must be the answer, although there is not a terminal on the back. Depending on which way the plug is put in the socket, the loop section of the antenna can read 115V above ground, so we definitely don't want to connect anything external to that.
The isolated section of loop of course has no voltage on it. Kevin provided a picture of a similar Emerson that ran a wire outside the back, so it must have been shipped with a coil of wire wrapped up around back. The wire on mine was long enough only to reach some point on the chassis, so I thought it was connected internally somehow. Must have been cut at some time in the past.
Thank you sir.
