Well, the higher the number the better. I am currently getting in the 90's for power and signal strength for satellite. My OTA power and strength usually is in the high 70's or 60's for my local channels, which also depends on distance, weather, and station's operation.
You can view all this information by: hitting the Voom button, pressing the green button, going to "system status", and going to the third screen, which you use the down button.
