Yes, each antenna must be set for the satellite and the location -
and the time if you want to aim it. You are asking a satellite dish
to become a sundial.
There are a few hundred satellites in geostationary orbit - each with
their own assigned slot. So yes each dish would need to be as
unique as a sundial.
But this could be very useful to the casual satellite user if they
ever want to re-aim the dish - a common task if wind or impact causes
it to move out of alignment. Re-aiming a dish then could be done
with out aid and without a live connection. Kind of like resetting a
sundial by the time of day.
I invented a device called a calibrated adjustable gnomon to be used
for the purpose of aiming a satellite
dish. http://sundialsetup.com I is very hard to make a product
without partnering with dish manufactures since it requires a very
accurate marking of center of the dish - or rather a very precise
marking of the axis of focus. And it seems that any dish
manufacturer can easily set this on their dish. Then once someone
knows the satellite, the time and their location, anyone under the
sun could aim a dish accurately.
Certainly any gnomon could be built onto the feed horn of the dish.
This really suggests an entire field of applied gnomonics. I am sure
there must be many more applications.

Oeps!
It must be: Is each antenna "customer tailored"?

Dear Dialists,
the "German Satellite TV Sets - producer" FUBA from
Muenster/Westphalia offers actually a special edition of "parabolic
sundial satellite antennas". Two versions are available. These have
an diameter of 85 cm. For the technical details look at:
