Yep, it's the XM Radio antenna.

 

Versa antenna!

 

The guy at Honda said mine was an S2K, but it looks different from what I've seen posted by others who say theirs are S2K as well.

No biggy, it's shorter than factory original, that's all I cared about. Sorry for the additional post.

 

ohh wow you couldn't see any of the details on the antenna in your earlier pic, like that numb on the tip. this one actually looks pretty good.

how much was this?

 

It came to about $26 including tax.

 

So glad these things don't have this cheesy roof antennas. Wish they'd just put them in the glass though.

IIRC, most cars use the same threads, or at least the same few variations. You could probably just grab an antenna at O'Reilly's or Kragen and have it work just fine.

 

Used the perrin antenna off of my old EVO. Fit like a charm!

 

post pics if you can

 

finally got my 4" antenna!! looks soo much better!!

 

are we measuring who has the shortest antenna?

 

I don’t know about you, but the competition is usually who has got the longest…

 

Acura RDX Antenna

 

Here is the length...off of a Honda Fit...Honda P/N: 39151-SWA-305

 

rofl love it

 

4 inch from pep boys

 

for this one Enzie bought (and I just installed on mine as well, GREAT MINDS THINK ALIKE)

Honda Part # 39151-STK-A01

$7.33 from Delray Acura, they do charge a hefty shipping - 10.95 for USPS Priority, but it still was under $20 so I'm happy.

Plus it looks HAWT.

and if you want to see the OEM comparison:

 

im starting to really like how the RDX antenna looks. i havent gone to a honda dealer to ask how much, i kinda feel weird driving my new scion tc into a honda dealership to buy a honda part.

 

^ Bah, don't feel weird. It's not like you're the first person to ever do it. Honda dealer here keeps S2K antennas on hand just because so many people want to buy them for other cars.

 

I bought a really small perrin stubby antenna. It does not work good at all. Next to no reception on the FM, and the HD doesn't work at all

 

Another good reason to go with Honda OEM, if it didn't work, Honda wouldn't use it.
