Greetings all, working on our '76 RL-1750 trying to fix the water leaks, we have what looks like a factory installed Signal Commander roof antenna...and it's causing a leak. Before I make the repair, I'm wondering if I should just remove it entirely? I'm not sure in this day and age if it would really serve any purpose for improving radio reception; and I'm told a lot of campgrounds now have cable hook-ups for TV anyway. Thoughts and ideas? Let me know, thanks!
I would remove the antenna and patch the hole. It's not going to do you much good in this day and age... If a roof antenna works, it's very likely that rabbit ears would too.
You'll need some gutter seal for the screw holes and a patch for the hole. Use RV putty at the edges and be sure to screw into previously placed wood backers. That will allow the screws to tighten and squeeze the putty for a good seal.
Once you are happy with the patch, use Proflex paint on sealant (3 coats) to seal it. Do not use caulk. Paint on Proflex is clear and very sticky. It works. Substituting products isn't a good idea in a case like this.
