I just got a DirecTv D10 receiver, does the foot print of DirecTv 5, at 72.5 cover Southern California, I know it say its conus, but is it really. I want to see if I can find it, do an auto detect to make show up in the signal strength screen and then get the 2 test channels, 495 & 496. I would be using 2, dual 18" dishes, an SMS-4/4 RP20 switch to the D10. I would be using an elevation of 28 degrees with an azimuth of 119 degrees, for zip code 91739 which is Rancho Cucamonga, Ca. So the questions are can I see the foot print here and secondly is this the right stuff to use.
