To answer your question: Subscription Satellite TV for many years used one frequency band So the same antenna that picked up DriecTV could pick up one of the DISHnetwork birds, and BellVu Express (Which actually uses Dish type antennas) and I can't recall the other Canadian provider. All you had to do was point it.
Today, we have HDTV, Now DirecHDTV here in the US uses TWO bands, one just for HD, and the old one everybody else uses (Starchoice that's the other one, I do not know much about them).
So that Generic Solo (Single or dual output but just one lens) Antenna was for DirecTV.. Or 1/2 of DISH (now 1/3 of DISH) or 1/2 of BellVu Express (Do not know if they have added a 3rd bird either).
The Script heads at the Sat provider actually know nothing about what you need.
But... Your antenna, if round, will pick up ONE satellite.. IE 92W (There is a good channel on that bird... Silver Screen). But it will not pick up ALL the programming.
With a bit of work, and a single receiver, you can use it though.. You just may need to re-point when you change channels.
I would recommend upgrade to the proper antenna though.
