So I have a J and M hidden antenna. I think I am going to pull the fairing and install this. As of now I have NO antenna, just a piece of wire going to the saddlebag area. So I am thinking that this will be better than nothing and cheaper than adding a antenna to the Tour Pack. And a cleaner look. I live in Glendale Arizona, and there are a lot of good stations here, and I can barely get any of them as it is. So I am hoping that the J and M will be better that what I have.
