Query: Cheap & Easy Satellite Signal Fix

We lost our satellite signal and determined it was was the old LNB by going up on a ladder and looking at it -- the plastic cover had disintegrated. Ordered this one and received a genuine RCA dual LNB in the mail a few days later. It's easy to remove the old one and replace with the new one. Signal came right back. No need for a costly service call.
