Well I just measured the jack on my Yaesu G-2800DXA rotator I have in the basement and it is NOT the same size. Yours measures 13/16 of an inch and mine is only 5/8 inch. Also mine has four key ways in it to ensure proper alignment when inserting the plug. The pin arrangement looks the same however. Also take note that the rotator housing on both yours and mine is flattened where the connector is mounted. A normal flat based bulkhead or panel mount connector will work perfectly. No need for shims etc as the surface is flat and not curved.
