Correct. However my point was does the two wire connection need to have a closed circuit so the locomotive will "see" the TMCC signal. On previous board designs it is not needed and this was usually one wire in previous command diesels.
One wire could break and the antenna would still be functional. The two contacts on the board are wired together. One wire to either or both contacts is sufficient. I am assuming the factory has wired all the antenna connectors with two wires so they can be used for either steam or diesel and then just tie them together on the diesels.
I just opened my RS11 which also has Alzheimers. It too has two wires soldered to the antenna plate.

Thanks Pete. Than I think what happened to mine was the antenna plate lost its adhesive to the shell and grounded the signal out on the frame . When it was sitting loose inside the unit .
