I ordered some goodies but I forgot to get a stubby antenna. I don't listen to FM much with the sat radio in there so I just took it off. Didn't even notice much difference in reception which was a pleasant surprise.
I didn't want to leave the threaded hole open to bird's nests and the like so I found a bolt that fit and just happenned to have this little black hollow tube that friction-fit over the bolt nicely.
I actually think it looks pretty good:

 

nice

 

The only negative with the stubby antenna is that the songs are shorter on the radio.
