I have a Slimline dish with 3 LNB's. While wiping the snow off of it this winter, I shoved my elbow through one of the white covers on the LNB's. It looks like a simple white piece of plastic that I can snap on/off. But where can I pick up a new one? Everything still works perfectly, but I imagine being exposed to the elements can't be good on the interior of the equipment. I've searched older forums, and haven't found quite the same question. If I have created a duplicate, I apologize. Thanks for your help!
