Please note that
@scopus is one of the top men on the UK dx scene, he has equipment that is drool fodder, worth quite a few bags of sand.
It would not be a low cost option to setup and install equipment to that level.
If you want have a reasonably good chance to get 3.0W feeds ooop North my suggestion would be to go for a 1.5m dish as minimum, preferably a 1.8m.
Perhaps look for something second hand on eBay or facebook, there are setups listed now and again and they have been selling at value wad lately.
