Is there such a thing? Im looking to roof mount this with my other antennas.

According to this, no.

Yes, because my dad used a GPS while traveling from Florida to New Jersey in a car to make it easier to get from destination to destination.


NO! GPS And satellite radio are two different things. They cannot share an antenna.


GPS and Radio are on 2 different frequencies GPS, GPS travels on a L1 Frequency up to 1575 MHz while radio is on BANDS, Like Sirius is on S band which holds DATA and Sound unlike GPS which holds DATA Only. So an Antenna that's on a car cannot receive both, the technology IS out there, but ONLY on NEW cars 2007 and UP

Umm, wow... copying and pasting an answer from Answers.com, which has to be the most full-of-fail site short of Yahoo Answers I've ever seen...

Anyway - yes, there are car manufacturers who are doing satellite and GPS in a single radome (two antennas in one unit). Both antennas require some tricks... GPS typically uses a +26dB LNA at the antenna, and sat radio is typically downconverted to IF at the antenna (that's how they get away with such small coax on the standard antennas).

I haven't seen any of the major LMR antenna manufacturers making such an antenna, but they are out there. I'd look at some of the OEM manufacturers for the various vehicle brands to see if one of them can sell you something. I know Ford is doing Sirius and GPS in a single puck.

These guys have done OEM on US and Euro cars forever. Looks like they may have products that will work. May NOT be available for non-oem though...

Thought Sirius/XM was on Ku band 12-14 Ghz? GPS for sure is on L Band.

Sirius and XM are on S-band. 2332.5-2345 for XM, 2320-2332.5 for Sirius.

If it were KU band you'd lose your satellite radio every time it rained heavily.

My Pontiac G8 has XM and GPS (for OnStar) in the same base.
