:idunno:
Onpage 17 of my radio manual it talks about SIRIUS radio already installed For USA cars only. Mine Displays SAT on the front of the Radio face:thinking:Do i really have it or is it also just ART WORK on the dash:rolleyes:
I have XM in my ASTRO delivery vans. Its addictive
Is the 2007 sprinter Antenna a duel purpose Antenna it looks different than the 2006? I also ordered the Wireing for the back up camera but no information is available for where its at, or a list of compatable cameras and displeys, that I have found.

I don't know about the SAT capability of the unit.

The T1N antennae couldn't be used for SAT; if I recall correctly, T1N owners had some lengthy discussions about where to best put the reception gizmo for reliablity.

The NCV3 antenna's specs are a mystery at the moment. The only clue is the equipment description:

Sales code RDK: Antenna for AM/FM, GSM, UMTS Network and GPS

GSM and UMTS are cell phone protocol standards.

GPS is a satellite-using application.
XM and Sirius are satellite-using applications.

The bandwidth requirements are significantly different, so I couldn't say the antenna specs for both GPS and SAT radio are identical.

Does anyone know the equipment or RF principles to comment more than my ill-informed guess?

Quickly...

GPS operates between 1200 and 1600 MHz

GSM (and most other cell phones) operates on 850 and 1900 MHz (in the US)

Satellite radio operates around 2.320 GHz

If you can get to the back of the antenna, you might find separate cables for each of the devices that it supports.

Cramming antennae for all of those into one housing would probably not provide great results for any of them.

thanks for the replys
right now i just use the magnetic one that comes with the XM Sky FI unit.
i would like to hook it up in the over head CB compartment.
another trip to Seattle from PDX 1200 miles on the 07 and I'm getting 22.3 mph :)
