Replacement Radio Antenna Anyone Know Of A Shorter Replacement Antenna For A 2009 Chevy Traverse?

Anyone know of a shorter replacement antenna for a 2009 Chevy Traverse? - replacement radio antenna

I bought a 2009 Chevy crossing and car antenna is about an inch too long to catch on in my garage without the garage door if they fit into position. To circumvent this problem, I anchored in a tilted position so that opens the door, and although it does not look so bad, you could say it's wrong.

Saturn dealer told me it was an alternative to short, his brother, Lambda, the Outlook, when I thought, but my Chevrolet Chevy and company could not find anything.

Does anyone know a replacement antenna just to maintain the functions of the XM radio and OnStar AM / FM?

Thank you.
