I'm guessing the railing is wood, not metal? If so, there's a few different things you can try. One is to cut a pice of wire about 8' long, solder or screw it into the bracket and drop it straight down below the antenna. That may work. You can also try getting a piece of copper and cut it into as big of a square or circle as you can get away with, and attach that below the bracket so It's touching the metal.
