Can anyone explain the technical requirements for installing XM Radio on a plane? Is it as simple as installing the antenna and running a wire to all the seats or is it as complicated as installing the DirecTV IFE? Do any issues arise due to altitude and speed?
I'm wondering why airlines haven't jumped all over it. It would seem that the costs to installing are lower then video based IFE. I know many airlines are struggling, but the costs can't be that high(or are they?).

XM rock & roll satellites work in S band (2.3GHz).
The antenna (I mean inside the packaging) is of the patch type, and while pretty well omnidirectional (in azimuth), it is good enough to pick signals between 45 and 90 degrees (= zenith) in the vertical plane.
Conclusion, it should preferably be mounted on the roof/ceiling, though it could possibly work well if mounted on the rear window (C172 and likes).
I did not find any ready-made XM antenna kit on the web that would fit and hold on an airplane.
Not sure about this, but I assume that such works (antenna has to be bolted) have to be performed by a licensed mechanics, and certified.
