My XM antenna is on the roof, just above the Reagan Light. I find the slicker it is, the more problems i have. Its mot easy to move that thing, but if you hit a bump doing 60-70mph, its tends to move ever so slightly, and yes, creating marring. I work in the sign making industry, and have access to 3M vinyl sheeting. So come Monday (You think i would have learned this earlier, but i guess i didnt want to admit it to myself) I will grab a little 2x2 peice, and lay in on the roof.....To tell the truth, Ill put up with a little indiscernable marring for my XM !!!
