Welcome to SatelliteGuys... dishnet or E* lnb's are "D" shaped Directtv or D* lnb's mounts are rectangular. You are talking sd (standard definetion) right? (althoght it does not matter) you would be better off with a dish 500 dish to get 110 and 119 (2 sats) and a dpp34 or 44 switch. You were talking new receivers right?(dp compatableA)
