im not sure how you guys are getting reception with your antenna inside the car?? especially with the poor reception of XM. when i was using XM, i couldnt even drive dowtown close to any tall buildings. or i would lose signal. sirius has cleared up that problem now. good reception everywhere. but i still had to mount the antenna on the roof.

i havent heard of a sigma antenna. is it supposed to get better reception than a regular sattelite antenna??

doesnt seem like anyone here has really got any experience with this yet on the 300's. ill probably just mount it to the front part of the trunk lid. ill post some pics for everyone if i ever get some days off to get this done.
