[QUOTE="2cvbloke, post: 596198, member: 199791"] Well, if you already have the parabola (dish), then you just need to find it's focal point, not so easy with an offset dish, but achievable using the sun or a bright light and a piece of card (paper's too flimsy)... :) And a Wok isn't a bad idea, as long as it's not the flat-bottomed type of course... :D However, a gas bottle base may not be quite suitable for the job, as it'll be quite small once you get the correct parabolic shape, and there's also the fact that "round" dishes are actually taller than they are wide (this is so the LNB sees a round reflection, otherwise the signal would be distorted and won't focus correctly), so you'd need to work out how to make the bottle bottom taller than it is wide... :) And another size issue is that it may not collect much signal, and if it does, it would have a rain-fade issue, but I suppose as a hobby-fashioned dish, that wouldn't matter too much... :) You know, this has rekindled my enthusiasm to get my old BSB minidish working, assuming I can find it... :D [/QUOTE]
