Our Sirius little magnetic antenna has sat up on the dash of our motorhome for 6 years. I put a little piece of the stuff you put in cabinets so the dishes stay in place under it never have had a problem.

My 1997 Safari has a fiberglass roof and I do NOT like to drill it for any reason. Also replaced the old radio and added as Sirius tuner. I tried the Puck Antenna on the dash bvut that was poor at best and a lot of reception cut outs. Somebody suggested I try the puck up on top of the front cap cabinets between them and the actual roof. Works Great.
