Winegard CarryOut GM1518 - DTV SD

The difference in DISH and DirecTV and HD is not HD but how the signal is broadcast. DISH uses 3 satellites that broadcast on the KU band so whatever signal they broadcast can be received by a dome style antenna. DirecTV 101 satellite also broadcasts on the KU band so whatever they broadcast from that satellite can be received by a dome (does not matter if it's SD or HD). The other 2 satellites that DirecTV uses broadcast on the KA band which domes cannot receive. DirecTV currently broadcast nearly ALL HD programming from the 2 KA band satellites. That's the only difference between the 2 services but it has a large impact on dome users. When DTV stops SD broadcast they will spread "some" of their HD programming to the 101 and whatever programming that is will still be able to be received by domes just as always.
