I have recently had a DirecWay high speed internet sattelite dish installed. The unit is one head that recieves my DirecTV signal and DirecWay high speed internet signal. I was wondering if this dish has the bandwidth capabilities to recieve the DirecTV HD signal. DirecTV's website says if you can see channel 99 then you dont have to purchase a new dish for getting HD signals, just the decoder box. I can see channel 99 so I am curious if I even have to purchase a seperate dish to get DirecTV HD?? Any help would be appreciated, thank you!
