Thanks David, that was very helpful! Doug, I assume you know the back is ground, and am gussing your question is what the black goes to, and it grounds to the chassis. The red connector is identified in the instructions. Bob

Surely the manual would have explained that if somebody had just read it.

The black ground terminal does not get a wire. It's connection to ground is made through the back panel ground plane. The solder mask is not covering the area around the mounting hole. The red terminal connects via a short wire to the ANT BNC center pin terminal wire on the bottom of the top PC board. W3BNO

Doug,

Please ignore the smart alecks in the group. I'm sure there are plenty of things they may not know but are too proud to ask. One think that may not be obvious from the manual is that you can use either the BNC connector for a coax fed antenna or the binding posts if your wire antenna is attached directly to the 4S Tuner. You should choose which ever method is appropriate for your application. Once the tuner has been built, if you choose binding posts, the black binding post may be connected to your station ground or possibly to a counterpoise wire if you are in a portable situation. The red post connects to your antenna wire. You will probably find some lengths work better than others. I don't want to speculate not knowing what you are trying to accomplish.
