I have a Ray Marine 45 STV Satellite dome from a previous owner already installed on my 405. The antenna unit powers up and tracks DTV at this time. I am trying to figure out what is needed to make the unit work at the TV's. I currently have DTV but may switch to Dish network for the boat use as I believe that Dish receives both analog and HD signals where DTV does not. I contacted DTV and it appears that you need a D12 or H24 receiver, but they want $100 plus a two year contract that they don't tell you about. Even if you purchase the units from a 3rd party provider, DTV still owns the unit. I am leaning toward Dish at this time and would like any direction available as I am not trying to re-invent the wheel. Just need to know what I need to ask for and if I have the vendor set the dish up at my home can I then install it on the boat. Thanks
