whtcrxghst Posted October 31, 2006 Report Share Posted October 31, 2006 Pioneer doesn't. Maybe it was an aftermarket company? Quote Link to post Share on other sites
SVT Amateur Posted October 31, 2006 Report Share Posted October 31, 2006 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.

hummer_h3 Posted October 31, 2006 Report Share Posted October 31, 2006 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. Quote Link to post Share on other sites
cntrylvr79 Posted November 1, 2006 Report Share Posted November 1, 2006 Can't forget, some cars have a metallic layer in the windsheild that can cause problems picking up gps/sat reception. Quote Link to post Share on other sites
themlruts Posted November 1, 2006 Author Report Share Posted November 1, 2006 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 Mike Quote Link to post Share on other sites

jimmy303 Posted November 11, 2006 Report Share Posted November 11, 2006 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.

lucasisola Posted November 12, 2006 Report Share Posted November 12, 2006 Small note....there are [b]3[/b] 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.

jimmy303 Posted November 13, 2006 Report Share Posted November 13, 2006 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. Quote Link to post Share on other sites
