The DirecTV receiver failed. It was one of two on the boat. It was connected to a ten year old KVH satellite dome that was always on. Here is the catch. The existing receivers are legacy receivers and are no longer available. The newer SWM (Single Wire Multi-switch) technology receivers are available everywhere but not compatible with the existing dome. In theory you can add a powered Multi-switch to get around this. Given the age of all of the gear coupled with the mess behind the entertainment center with miles of unlabeled white coax cable it was decided to start anew. It seemed so simple at the time and then promptly went to hell in a hand basket when I tried to pull the new wiring.
