Newbie - DIY - Antenna leak and removal/ roof patch

Hey Everybody! Newbie here. I have just made my first foray in to RV land. Glad to have found you all.
Plan is to travel and then find land to create a permaculture homestead, living in the RV while building natural building. Big adventure!
I have an old Coachmen C class 22 footer. I have put pretty big bucks into it already, and looking to do a few things myself, because man o' man is RV tech labor expensive! I value their work, but honestly I feel I could do some myself. I'm handy, and gotta slow down the money pipeline.
Here's my first question for those of you willing to add your two cents. RE: ANTENNA
1) Had a pressure test done for leak detection. They say the antenna is a potential problem spot and I need to replace it. Since I won't ever use it, and it's old, I'm not really interested in replacing it. BUT I do need to make sure it won't leak. Can I just leave it out and patch it? Like maybe a metal/ aluminum plate screwed over the hole, with Dicor or Eternabond, or???
Or am I asking for trouble and should just pay the $300-400 ?

Has anybody done this successfully and have it hold up over time?

Many thanks in advance.
Jenn

  • Chris, thanks! Pretty sure my antenna is the infamous batwing. I asked the the RV dealer repair shop if they could just seal it up. They said the antenna cannot be repaired ( it was working) and adding sealing to it won't work. I really don't understand that, but I asked them twice about this. I don't even care if it's so sealed that I can't use the antenna. I just want to stop any water intrusion that might occur. Why should that be so complicated?
    I'll again ask them and include your suggestion of a quad O ring
  • I would question the diagnoses- if you have the near ubiquitous Winegard "Batwing" Sensar antenna, a bit of sealant and a new quad o ring are all that is needed- if your base looks like this:



    *Any* penetration through the roof is a "potential issue", but that doesn't mean you have to remove everything.
  • HI jmckelvy, and thanks for the reply and welcome :)

    My roof is on a 1998 Coachmen C class, rubber roof. Assuming it's just wood underneath.
  • I see no reason why you can't remove it and seal the remaining hole.

    The actual details would depend on the existing roof material and structure.

    By the way welcome to RV.net. There are lots of good forums.
