Shark Fin Antenna Assembly

RyderSU · 11-29-2019, 05:36 PM

Hey guys,

So I removed my fin to take the wrap off my roof, just have a couple of questions.

What adhesive did you use to put it back on? And if it's 3m tape, what thickness? Thanks guys so much!

I also used 3M and worked great. I believe it was the 1/8 thickness. You don't want it to stand proud between roof and fin. Hope it works for you. I did make sure all surface was clean...and made sure tape was cut to fit completely.

I used 3M Weatherstrip Adhesive and is a more permanent solution like the oem Betalink. It’s cheap and you could find it at Autozone etc.

3M VHB 2 cm wide, and I cut it to size. In regards to thickness I have no clue because it only comes in one thickness, just variations in width. Just wrap it uniformly and at the same level around the edge of the antenna bottom to give it a good seal vs. water.
