can someone who has the Factory XM antenna located on the Roof of the car get some dimensions for me??

Could you take a measurement, from the top of the rear window to the back of the XM antenna?.....maybe even a pic to show the exactly where you have measured from

OR if anyone has the FSM'* that describe where the antenna should be placed that would also be awseome

Thanks Guys

Sorry, won't be in the FSM. Already been down that road :? Then, when I called GM (corporate) they refused to provide the location and size because adding the antenna is considered a "modification" and they won't support mods (even though it was a factory option)

I believe the 2003 and 2004 used different antennas. If you would like I can do this tonight for you on my 04.

yes the antennas are different, although they may be the same length..

could you get the measurement of the entire antenna, and also the location on the roof.....Pics??

I will do it tonight after I get home from work.

Pat:
Is this what you needed?

yes that is perfect..

THANK YOU

now to compare to the 03 Antenna..........
