I searched to see if anyone had ever done this and couldn't find anything. I removed the antenna base yesterday to clean under it and repaint it and wanted to see how a black antenna would look. I had and old antenna that I shortened, but the threads were different and I didnt want to cut the stock antenna or paint it at this point. So I got some heat shrink 3/8 I think about an inch long for the base on the antenna then I used ¼ on the rest of it. No noise and I think it looks good.
