My garage door somehow took my antenna on 2009 LR3 & dislodged it. Anyway, it looks as if it wasn't bolted down but maybe some VHB tape held it on. It separated the wire which is an easy fix but does anyone know anything how to remount it to the roof? Thanks for help.

 

I lost mine in the car wash and never bothered to reinstall-it's the Sirius/XM antenna, so if you don't use that feature I wouldn't bother.
Otherwise the double sided mounting tape of your choice. I have some Muscle Bound brand double sided foam that is intended for attaching bathroom tile but worked well for attaching my hood letters.

 

It is also the cell phone antenna. There are different versions of the antenna based on options. In this dat an age, though, it really is not needed.
