[QUOTE="koansrc, post: 506259, member: 244790"] :-DOH! well I guess that means I'm looking for something spherical again (!) to mold a dish from (great idea HB13DISH). But I figure it has to be 40cm in diameter with an f/d of either .4 or .6. Is the f/d calculation the same for spheres ??? To all those that claimed aluminium tin foil works for satellite dishes .... well it does. When I originally posted that it couldn't receive anything, I meant as a subreflector. I tried it as a plain dish today ( as suggested ) and aimed for 13o Hotbird. Easily locked on to various freqs. I suppose I ought to do a proper test and compare the aluminium foil dish to a proper one and benchmark it etc or even hook up a TV to see what exactly I'm getting, but ... I'm too busy looking out for something spherical about 40cm wide at present :) Pictures from the tuning at 193o, 11770, H, 27500 [/QUOTE]
