Yeah, the rebroadcast from the antannae to the radio seemed weird to me: why do it in a car. In order to rebroadcast you have to have power there, and if your running power there, why not just run the signal back? Or are we going to use batteries? The size doesn't bother me-- the telephony handsets have small atannaes and they have a lot more difficult of a problem to solve (though they are closer). The sat can broadcast at full power since its only one way. But I don't understand how the directionality will work, I don't understand phased array antannaes. Dragonfly
