My wife backed into the garage door with our new 2021 odyssey when the door was not fully opened and the antenna on the roof got damaged.

I put a new antenna but seeing some gaps between the antenna and the roof (see pics) and wondering if this is normal.
Can someone tell me how's yours look like? Is there gap like mine or does it sit flush to the roof with no gap?

Definitely not normal. Is that an OEM part?

How is it attached? If there are screws below, any chance to tighten more? Maybe the sheet metal got slightly deformed by impact?

Its attached by single screw. I tightened it hard already. I know I am going to break something if I tighten more.

So you guys have no gaps there?

My Elite has no gaps, might be worth going to a PaintDentRemover, I would remove the fin before you go. Or you could try using a suction cup to pull the roof up on that (corner) side.

I would go to the dent repair guys before I would touch anything else.

The PDR guy that we used for having hard ball sized hail on the wide area dents used a suction cup with glue to get 3 areas that had covered roughly a 32" impact area and as he told me that PDR is really the art of smothing out smaller dents. I was really suprised how he did on the overall 2008 Toyota Highlander we still have today, as they say no painting needed. Howeer a 2004 RX330 Lexus did not fair well, The took out front and back windshield and both side mirrors, and the body was over 80 percent dented very deeply. It hit so hard the sun roof glass shattered and hit the railngs on the side ant the estimate for the sun roof showed to replace everything on the sun roof. The PDR price alone was $18,990 and the sun roof with all the other glass came in $7,000. They highly recommended that we should replace the carpet and insulation, when we originally opened the doors, water came out. At that time we had the vehicle for 7 years and had 174,000 miles (nothing was wrong before the hail and rain) and the Insurance company recommended to take the value of the car, which I planned on doing. This was one of the cars I would have drove the wheels off the car on. Out house had equal damage, the hail went through the roof and into the attic, so new shingles/decking/gutters and vinyl siding two windows-glass only on 2nd floor and a weber bbq grill that looked like someone had hit it with a ball pein 12lb hammer. It was not a good year for us for a lot of people. We was with friends that picked us up at the opposite West end of Omaha at a restaurant and I happen to look at a TV showing weather and the radar showed a dark purple color where we lived at, thankfully no tornado.

I dont see any dent. so its hard to figure out why it is not flush to the roof.
As long as I dont get water leak i guess this should be ok. I added butyl tapes around the hole to make it water tight. hope this is ok.

Sorry to hear this happened to your new van. I had the exact same thing happen to my Odyssey. It looks exactly how yours does, but I have not replaced the antenna because I don’t know how to remove it. How do you access the screw? I would imagine the mounting bracket that the bolt screws into likely bent from the impact, causing it to sit like this. I was going to try and see if that was the case and if I could bend the bracket back into place.

I had a similar thing happen yesterday. I used this 2011-2017 video to help me remove and inspect the antenna.


My antenna got pushed towards the front of the vehicle and up so the hole in the roof is pushed up/out and causes the antenna to sit high and have gaps. I added some waterproof foam tape, but it is too thick.

@thelinux what size tape did you use? If you have link that would be most helpful.

Basically, you loosen the rear side of inside roof lining. then you can reach it easily. do some searc on youtube. you can easily find some helpful video.
