I've just bought a 2005 vintage motorhome It has an Oyster Satellite dish, the box which tells the dish to look for satellites, and an ordinary domestic TV set. I have an inverter too as we often camp wild on 12V. We want to watch normal UK if poss, or failing that, other channels. We go to France, Spain, and other European countries a lot. What receiver do I need? Is it a free to air box I need? If so, what model do funsters recommend?
