BLACK CARBON FIBER SHORT STUBBY BILLET 3" INCH ANTENNA - eBay (item 260397662999 end time Feb-10-11 13:05:41 PST) I hope it works. If it doesn't search the forum for antenna and you will be able to find it. It costs less than $20 with shipping. As for reception the antenna is only for FM and I don't notice alot of degridation. The hump the antenna mounts to is the sirius antenna. Please post if you have any other questions.
