I was shopping for head units, and will get one that's satellite radio ready. However, I'm not inclined to mount the satellite antenna outside the Blazer, and was wondering if any other Blazer owners had any experience with mounting the satellite radio antenna inside the Blazer's fiberglass shell. It would be an easy task to fab up a little under-roof mount on the underside of the shell. My home XM antenna seems to be relatively forgiving as far as having wood in between the satellite and the antenna goes. I'd figure that the fiberglass would also be fairly transparent to the signal, but I thought I'd ask. Thanks in advance for any feedback!
