FWIW, you wont need a satellite dish (some of them operate in the L Band), unless you are very much out of the footprint, with a weak signal. Nevertheless, a parabolic reflector will give you a higher gain, but again that's not the choice for a receiving aerial in a moving vehicle. Such use cases use in some cases a flat panel antenna or an antenna array. DVB-RCS wouldn't work as it needs to be really pointed to the satellite, nor any Ku or C band transponders. The lower you are in the spectrum, the more likely to have a better reception with a lower gain reflector. http://en.wikipedia.org/wiki/1worldspace http://www.worldspace.com/howitworks/receivers/AGFwssr.html http://www.worldspace.com/coveragemaps/antennaguide.html http://www.satdirectory.com/--worldspace.html Regards, Manu -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
