OK, I have come to the conclusion that my SQ issues with XM have to do with shitty reception using the little mag antenna. I have been using the home antenna THRU THE WALLS OF MY HOUSE and get better SQ than in the boat or car. I'm thinking of mounting the home antenna in the boat under the dash out of site. I think it may receive better since its so much larger than the little mag one. Either that or maybe getting the marine antenna. I just do not want to mount that ant on the boat. Anyone have any input?
Thanks
