These are the dishes required to get either Sky or free to air programmes from the UK
You can compare them with the small dish required for Telmicro in the right foreground and understand why that system was so popular.
Aerial for Spanish terrestrial TV and the dish for Digital+. Much neater don't you think?
My neighbour, who is obviously a tele addict, has these two small dishes on one side of his house which are pointing to different satellites and a terrestrial aerial on the other side but still can't get BBC! NB For some reason there's no cable connected to the dish on the right.
So you pays your money and takes your choice.
