I honestly don't know about a portable system. It took the installers a quite a bit of time to aim the dish since it had to align with 3 satellites instead of the usual two. Also the dish is a parabolic shape that needs to have all 3 axis adjusted properly. My system was a first for the crew and took a couple of days to figure out. I have reservations that it would work with a motorhome but I don't know. Check with a motorhome dealer/manufacturer, I am sure that others have tried it. Motorhomers are pretty ingenious people, if there is a way, somebody has found it 8^)
Not a chance for current internet technology (StarBand etc.). FCC is VERY strict about uplink parameters (must hit a transponder 22,300 miles away) and the polorizing filter inside the feedhorn has to adjusted while getting feedback numbers from the ISP.
FYI...if the Echostar/DirecTV merger goes through, they will move the platform to Spaceway
Uncle - the GPS truck tracking system is very specialized and it's sort of like soccer vs football - similar, but not the same.
