The pay tv systems use much higher power than the fta birds do, so they can get away with a smaller dish. And their signals are using "circular polarization"-- you want a real ku dish for free to air that has a linear lnbf (linear polarization). Find a used dish on craigslist or look around in your area for an unused ku dish, like on a closed store or gas station,car dealership. If you're lucky you might find an old primestar tv dish, those were before dish/directv and used linear lnbfs, plus they are big enough for good free to air use. A lot of us are using them now. Or, of course you can always buy one and have it shipped, but anything bigger than about 1meter will get expensive on shipping.
