I bought this 20 mm shrink wrap, two part epoxyed the antenna, put the shrink wrap over and heat gunned it. Has stayed in for 1000 miles so far and is solid as a rock. Much cheaper and easier than installing a new one - if you donít mind the red. The black ones are larger, but you could put one over the red one - if it bothers you. The red is easier to find in the RV show parking lot.
