If you are positive you have the elevation and azimuth properly set, you need to tune your receiver to a known active transponder. The signal strength is only an indicator that you have power to the lnb. If you have zero quality, either you are not set up properly with the mechanical alignment of the dish or you are not tuned to an active transponder. Is this a motorized or fixed setup? What receiver and lnb are you using? You are aiming at a satellite located at 100E. Are you within the footprint of this satellite?
