The antenna on my 2011 Sport is too long. I have above-head storage shelves in my garage that only allow about a 24" long antenna. I bought a shorter one but it rusted in the threads, and the reception was not as good. Is there a quality after market antenna under 24 inches?

 

I had a black one from these guys: AMI : Automotive Accessories for Cars and Trucks

Same reception as the stock one and looks a lot better too!
