I've installed a round dish with one dual LNB. I ran two cables to the house and both end at a twin static discharge block. Then, I ran one cable from one of these lead-ins into the house to the D* receiver so I can get signals from the 101 sat to one TV. Now, I'm thinking about replacing the round dish with an oval twin dual LNB setup. Will I now need four lead-ins from the dish to the house? My receiver is a Plus unit, and I thought I'd play around with Para Todos off of the 119 sat, and eventually get an HDTV receiver.
