[Moon] F/D choice ?

[fr5dnpm at wanadoo.fr]

Hi everybody,

What is the simplest source with good efficiency that one can build easily for 
23cms?
Easy building may not be that easy for me in term of raw materiel like 
copper...I'm collecting box for the moment (milk, cookies, etc...)

What best F/D for this source?

Linear pol i guess on 23 ?

Is there a way to find aluminium mesh in France (I may come to France end 2007) 
for say a 4m dish ? Also some Strong linear actuator for such a dish ?

Any source of second hand lna/rx converter/transverter/relay for 23?

I did find some 4.5m dish in china for 230$, but the minimum order is 100pcs, so 
bad!
