I ride an '05RKC and I use a thin strip of metal with a right-angle bend at the top on which I mount the magnetic antenna. This metal strip mounts to the windshield with those little rubber section cups, usually on the top-right corner as my riding is done mostly in the Yukon and Alaska, which puts the XM satellite in the South-East. If I mount the antenna anywhere else on the windshield, I get blockage of the signal. So far it's worked OK.
