Not so with 4dtv! And the picture is better than dbs.

Not that much. But to look at two different satellits, the feedhorns
would have to be off center of the focal point of the dish. That also
degrades signal. Check out that last website above. They show dishes
with multiple feedhorns and explain how far off they can be from
center,

Use two dishes then. Them little frisbees are pretty cheap and compact.
The only time I seem to lose digital signal with my big dish is during
the times the sun lines up with the satellite and dish for a few
minutes a few days twice a year. I've never had rain fade, and only had
a few sparkles in analog when the snow started covering the dish.

I believe though that even one way internet shared on one BUD with the
TV would be inconvenient at least however, as most likely the satellite
desired to watch a feed on would not be the one with internet signal.
The fight would be on with the family on where to point the dish.

With the expense of satellite two way internet, it should pretty much
have to be the only option. However, looking in a recent camping
magazine, I see it advertised for RV's using in motion tracking
antennas. Those well to do retired full time RV'ers will probably go
for it with gusto!
