If you have an Eastern Arc, can you put a western arc LNB in it? I have eastern arc and get low signals. I used to get great signals with 110/119. I want to do WA with 61.5 wing dish. Can I buy a 110/119/129 LNB and put it in a dish 1000.4 EA? In other words swap out the LNB's? Anyones help would be apprecited.
