All you need to do is mount the LNBF at the correct distance from the dish. Increase the signal to noise and say goodbye to Rain Fade or low signal.
When you install the LNBF, make sure the dish is at zero position (TRUE SOUTH). The LNBF must be parallel (or in other words straight - no skew - ) with your True South.
Then move your dish to a satellite (i.e. T5 or any other one you like). Check the signal strength and quality on your receiver. You might want to push the LNBF in or pull out away from your dish to adjust to your dish's focal point and get maximum signal strength/quality.
