Well, now that you describe it, I think that I have seen photos of such a
plug.  Might have been made by Johnson.

As a novice back in '72 I had a box of them.  They were clear acrylic and
rectangular with side screws and leaf springs.  I could swear it was the
same pin size/spacing used on the back of the Johnson Viking II for an
external T/R relay.  I used them on the Viking as well.  I seem to recall
they were also used as 300-ohm TV plugs back in the '60s.  Anyone remember
these?

I just pulled apart an odd-frequency FT-243.  As Bob suggested, there's a
channel along the top that small coax can be routed through.  I can clearly
mark the ground side.
