This afternoon made the doubler for the ELT antenna. This doubler is a 2" circle of .040 aluminum with a 1/2" hole in the center. I plan to rivet it on as well. I alumipreped and alodined the three antenna doublers and used scotch bright to remove the epoxy primer from under the antenna mounts. After it was nice and bright, I alodined the skin surface. I also installed my nut-plates onto the antenna doublers tomorrow I will rivet these in place.
