Using an antenna on a dish would work for XM if you put the feed at the
correct focal point for C band (DirectTV and Dish are Ku band), but
would be a problem for Sirius because their three satellites are not
GEO. They are LEO in an eliptical orbit so you would need the latest
Keplers and a tracking antenna. Also they are at 2.3 Ghz.

So the antennas on the bird are directional targeted at the US? Otherwise
I would think that an equal area below the equator would be covered.

No, most US-targeted satellite services have directional antennas pointed
this way. It's bad enough trying to get enough field strength to lock up
the cheap XM/Sirius receivers with miniscule antennas so tiny. They're
pointed to the States, all right.

Wonder how they'd work duct taped to the side of the feedhorn of the Dish
Network antenna pointed at the XM bird?....hmm....

Having a more serious receiver antenna capture area would seem to extend
their range much farther than that little plastic blob magmounted to the
fire extinguisher.
