The accompanying sketch shows how I added a coaxial connector to the antenna terminal of my RME 4350 receiver. This method eliminates the need for drilling a hole in the receiver's chassis to mount the connector. Remove the head from a 6-32 screw and solder the screw to the center conductor of the coax connector. The connector is then screwed into the terminal strip with a section of small tubing inserted as shown in the sketch. Another 6-32 screw is inserted through one of the holes in the connector flange and is screwed into the other antenna terminal. Also connected to this screw is a lead that is attached to the ground terminal on the terminal strip. Almost any terminal strip can be used with this scheme since spacing between the lugs seems to be a standard ½ inch, which is just the right measurement to line up with the holes in the SO-239 connector.
