Cleaned up my Directional Coupler project. Labeled the ports and even added the electrical characteristics at different frequencies on the bottom. I then added a coat of lacquer resin to seal in that beautiful copper color (which otherwise would go brown as it oxidized).
The final result has a sort of beauty to it.
