It's not so much a question of reception as it is a question of reliability. I've never had an XM antenna fail but I have had a Sirius antenna fail :worried:

Ahhh. Good point. We do have a new sirius car antenna made by TRAM. It has a thicker cable on it so in theory it will last longer. We have had it for 6 months and we're very happy with it. Tram Square Car Antenna for Sirius
