King Hummer Posted April 11, 2007 Report Share Posted April 11, 2007 Can anyone confirm that they have installed both Sirius and XM together and it works perfectly fine??? I am looking to get the best of both worlds with Sirius music and XM NAvtraffic. Thank you. Quote Link to post Share on other sites
naplesbill Posted April 11, 2007 Report Share Posted April 11, 2007 Yes it works perfectly. As long as you use the Pioneer XM tuner(no turk products) and the Sirius PNR1 or PNR2. That is what I have installed in my car. Quote Link to post Share on other sites

SuperH Posted April 11, 2007 Report Share Posted April 11, 2007 Yes, I've been doing this since June of 2005. No problems! Quote Link to post Share on other sites
strez Posted April 12, 2007 Report Share Posted April 12, 2007 Has anyone that has done this used the same antenna for both XM and Sirius? I know you need a different antenna for the GPS - that's a given - so I can live with two antennas on my roof, but hate to add a third. Seems like we should be able to use the same antenna for both the XM and Sirius signals. The above assumption on my part is based upon the fact that the two signals are adjacent to one another (2320MHz - 2345MHz, with Sirius utilizing the lower half, and XM taking the upper half of the frequency spectrum) and I suspect that neither the XM nor Sirius antennas are designed to filter out the other signals (probably some roll-off where the other signal may be degraded, but I suspect under most circumstances the other signal will still be strong enough to work). Ideally I'd like to see the frequency response plots for various antennas to determine whether or not it will work, but that type of info is likely unavailable to the public. Anyone tried this? -Jeff Quote Link to post Share on other sites
naplesbill Posted April 12, 2007 Report Share Posted April 12, 2007 I have heard that the Sirius antenna works for both(and I've used them for both services)but the XM antenna has problems with Sirius signals. I don't know of a way to share the connection though? Is there some type of y adapter available? I did not put my gps antenna on the roof. It is installed on the dash and I checked the signal strength and it was more than 2/3rds everytime I checked it. I currently have the XM antenna on the dash but I plan to put it on the roof this weekend. I am using a Sirius antenna for both services. I am not sharing one antenna though.

whtcrxghst Posted April 12, 2007 Report Share Posted April 12, 2007 Earlier thread on this reported that XM antennas won't receive the Sirius ground repeater network, and vice versa Quote Link to post Share on other sites

strez Posted April 12, 2007 Report Share Posted April 12, 2007 I am using a Sirius antenna for both services. I am not sharing one antenna though. So you are unplugging/plugging the single antenna from one receiver to the other each time you want to listen to the other service? -Jeff Quote Link to post Share on other sites

Try removing one of the antennas instead and use the adapter I pointed out a few posts earlier . . . let me know if it works - if so, I'll do the same with my install . . . you get to be the Guinea pig . . . ! -Jeff Quote Link to post Share on other sites
naplesbill Posted April 13, 2007 Report Share Posted April 13, 2007 Looking at the pic and the info for that link it appears that this adapter is to allow using an antenna with dual outputs to go into one tuner, not one output into two tuners. The problem will be the wrong male/female connectivity. I talked to my brother(he works for Sirius) about this just now. He basically confirmed that the antennas will work with each service but the Sirius has a better range. He also stated that the XM terrestrial signal will not perform as well when using a Sirius antenna. The other issue is that you will have to block DC from one of the tuners or both of them will try to power the antenna. Also, you will lose some antenna performance(DB) if you connect more than one unit. This may require an amplifier. It hardly seems worth it to me now. Quote Link to post Share on other sites
