So, here is the final antenna. As can be seen, I went with a white solder mask to give it a unique look, and protect the copper tracks from tarnishing. I added a black silkscreen outline of the opposing antenna element. I had thought that the copper would be more visible beneath the white trace than it is. If I had known just how well the white soldermask would obscure the track, I may have done something different with the silkscreen.
