I don't have the factory antenna, but added XM using the XM Direct package which comes with a small little antenna that looks the size of a computer mouse.

However, despite being on the roof, I get enough drop outs that it's bugging me. I have seen the Terk antennas on Froogle, but I don't know that that will be any better than the "mouse" that comes with XM Direct.

Any recommendations/links for (single lead) XM antennas that get strong reception (and hopefully are not quite as big and ugly as the infiniti stock factory one)?

Thanks!
