Do they make a combo antenna. I just added Xm to my N2 and i need to mount the atenna. I thought i say way back they mad a combo. So I onlt have move thing on my roof.
Thanks
Mike

Pioneer doesn't. Maybe it was an aftermarket company?

There's actually no need to mount on the roof. I successfully mounted both my GPS and Sirius antenna under my dash (I just made sure there was no metal above them) and have had no reception problems with either.

You will have NO problems mounted any GPS antenna under the dash, with no metal above it. The GPS network of satellites will always allow for multiple satellites to be locked on when traveling in any direction.
However, XM has only two satellites, one approx. over AL/GA, the other approx. over NM/AZ. So, if you mounted the XM antenna under the dash, and you were going north when north of the satellites, the direct line from the metal of the roof might cause a problem. Same primarily goes for Sirius.
However, if you are in a urban area, both XM and Sirius have ground repeaters that you can pick up on.

Can't forget, some cars have a metallic layer in the windsheild that can cause problems picking up gps/sat reception.

Yea my gps works fine but XM is a big problem. But since i am going to put one up i may as well do both. I wonder if i can make an encloser for both of them to fit in. Any one have and Ideas? I want to make something sleek and professionl looking.
THanks

What kind of car, and where are you located?

I am driving a 99 jeep cherokee sport and i am in ct New Haven/Hartford Area.

You shouldn't have a problem with reception if you put the antenna inside on top of the dash, as long as you use a small piece of metal under it, like the one that came with the nav antenna.

Small note....there are 3 satellites for Sirius and instead of being stationary the three rotate around the earth. Two are always above the US and the third is around the other side of the earth. This makes under dash Sirius antennas even more susceptible to fading reception, at least in my experience.

Yeah depends a lot on where you are in the States and how colse you are to a terrrestrial repeater.

Actually, Sirius uses no dedicated satellites, instead they rent bandwidth from other telecommunication companies' satellites. They also use terrestrial repeaters much more than XM. XM owns the 2 largest privately owned satellites ever put into orbit, Rock and Roll, and they sit over Maine and San Diego. The amount of badwidth available to XM because of this is staggering. We aren't too far away from mobile broadband internet or video on demand through XM services. I can't wait for the future, with flying cars and all.

OOH OOH The Jetson;s is coming true!! SIgn me up I want one of them fancy flying cars.

Already on the list.....

WTF is this garbage? Do you know anything about SatRad? Sirius has 3 of their own personally owned satellites in orbit. XM Satellite just launched their fourth satellite two weeks ago (Now XM has Rock, Roll, Rythym, and Blues) in geosynchrynous orbit. Also Sirius' terrestrial repeater system is miniscule compared to XM's. XM built an entire terrestrial repeater network before they even launched their service 5 years ago, and Sirius only started building a repeater network less than two years ago!
Here is a link to the launch of XM-4 (nicknamed Blues) that happened two weeks ago.

Dude, throw away the newspaper you have from 2001!

Now, now everyone relax. It's just radio that's all. nothing more nothing less.

I haven't followed up on this in a while, had no idea XM had 2 more, that's badass! Last I remember, XM didn't need to rely on terrestrial repeaters nearly as much as Sirius, because their satellite coverage was so much more effective. But, as with anything in the technology field, things change so fast, it's hard to keep informed. Thanks for the new info, Paisan!
