Anyone know if this antenna can be loosened to lift enough to seal under it? All from above the roof? Want to seal under it not just around it of possible.

 

I had the one on passenger side leaking and I had to pull headliner partially down to tighten a nut that held it on, im assuming your in same boat there, you can pull the trim on pillar and inside sunroof trim and take visor off and pull headliner part way down for access, that's how I git at mine, had to look up how to get visor off its a pain but found instructions on here somewhere
