Measuring Focal length...

Measuring Focal length....

Once you have the scalar ring in place, you will need to measure the focal length of the dish and ensure it closely matches that given by the manufacturer. You need to measure from the absolute center of the dish to the inner surface of the scalar ring. If your dish has a center piece, you will have to add about ½ an inch to your measurement. Make sure that the focal distance is within 1 inch of the manufacturer’s specifications. Remember, you will be able to fine-tune the focal length later when you position the LNB in and out of the scalar ring.
