Anyone know of or have one? I just jumped back in the XM pool due to there offer of $25 for five months with no activation fee. Problem is, a few months ago I bought a new BBQ grill and when I took it out of my van, I inadvertently cut the antenna wire. It was no big deal as I had dumped my sub a while back. I do have another one, but it is the one I used to use years ago when I was working in a patrol car. I would just undock the Roady, and had a second antenna and power cord. Problem is, from the wear and tear of hooking it up every day, it has a short in it. Now I have looked on line, but all they have are these short corded ones: So I am looking for one with a longer cord. Anyone?
