Creativepart....thank you, thank you. I bought a new (2014) 3051S with 3 TV's and the sales team, technicians, etc., all said only the MAIN TV was wired for satellite. I've been scratching my head for some time now and always knew i could add a 'switch' box, run cables, etc., but it just didn't make sense to me.
Anyway, after reading this thread and the details you provided (which were very clear) i was able to get the satellite working for all 3 TV's from one (1) satellite box. I now only have a minor issue. The EXTERNAL TV only appears to have picked up some sort of interference (slight waviness in the picture). Again, only on the external TV and only on satellite. ANY IDEAS.
Otherwise thoroughly happy with our MH and certainly this forum.
