My neighbor was restoring an older house and was getting rid of the fairly new SWM Slimline Dish with a single output. I have an older Phase 3 (oval dish) with 4 outputs and the H-100 receiver (HD receiver but I can no longer get the HD channels with my older dish). Is it as simple as switching out my old dish for the new SWM Slimline Dish or will I need to upgrade the receiver as well to receive HD stations (I do have an older HD package - but can not receive the HD channels)?
