[Moon] [Moon-net] F/D choice ?

Hello friends,

Many thanks to everybody who answers the questions. I'm having more and more 
idea about the dish and source to use.
I'd like to go for a 4m as it seems to be a good compromise between gain, 
mechanical construction... I have the feeling that there's a point after which 
things come very quickly difficult in term of dish structure, weight, pointing 
accuracy etc...
Will see.
Again many thks for all reply and comments.
I really appreciate it.
