[QUOTE="normsky, post: 624434, member: 197396"] Actually common satellite dishes are in the shape of a circular paraboloid. Which most certainly isn't what is produced by cutting a section from a sphere. Only waves origininating at the center of the sphere would all be reflected to the same point. Pretty useless for focussing parallel waves from a distant source. As far as the sugar is concerned I was very interested to read this. Shame I saw it so late in the day. [/QUOTE]
