Are there plans to move the antennae on the Malibu, Colorado, etc. to the rear of the roof, like the Impala & Monte? Placing the XM & OnStar antennae on the front edge really looks like arse, especially on lighter colors! :angry:

The Impala & Monte have a nice XM antenna at the rear of the car, though the thru-glass OnStar is ugly. I'd like to see a body-colored "sharkfin" housing that can operate as an XM and/or OnStar antenna, instead of the ugly duo. (like Audi, BMW, etc)

Anyone have an inside scoop?

UGLY:


BETTER:

You would think they could hide it in the ceiling or behind the grill or something, it's a digital signal isn't it? Shouldn't it be less effected by signal noise so they could better hide it??

Only the XM signal is digital, OnStar uses an Analog signal. The link below is from GM’s Technology Preview Displays, and shows that GM is working on getting OnStar and XM’s antenna merged into one unit. Also it must be said that, black vehicles have a tendency to reduce signal strength, therefore, a body integrated antenna’s performance would be subject to the body color, which would be unacceptable, and would result in mass complaining. Also an analog system’s performance is also dependant on a line of sight based theory. As a result, a small antenna, adds a sporty feeling to the vehicle when placed in the right location and shaped effectively and you get the best reception. My guess as to why GM is installing the antennas on the front of the car is probably due to the fact that the majority of the vehicles that have them mounted there are offered with spoiler style sunroofs which would cover the antenna, and reduce signal strength when the sunroof was open.
