I have been looking at the footprint for 1w at Lyngsat. The map shows "Blue Lines" and numbers. It is the numbers I need help with please, what size dish is required if the number shows 52.
Help would be appreciated.

Sounds complicated. I live in the South East of the UK and have a 1metre dish. Gets 1W with no probs. I think 80cm would probably be the minimum from here.

I can get 1w in the midlands of a 45cm Sky mini dish.

eirp 52 sounds like close to the centre of the beam small dish of 60cm or less should pick up this beam

I have a graph similar to the table in manic01's post.

Don't take any notice of the dish sizes below 45cm as they are not feasible. As a dish gets smaller its acceptance angle gets larger such that at 45cm the transmission from an adjacent satellite (say 3 degrees away) would start to interfere with the desired satellite. It is one of the reasons that Sly went from a vertical elliptic offset dish to a horizontal elliptic offset dish.
