[QUOTE="casser, post: 596465, member: 264731"] All you need is to fill a ball with the correct material, or if it´s possible, make a sphere with that material...nothing more is needed. But i recommend to try a smaller version (ex 15/20cm) just to understand the antenna, before starting in bigger versions. I never confirmed bigger full spheres versions than 25cm to work like predicted, it can be a bad surprise. I believe that a 25cm version can receive up to 50dBW satellite. About the materials, there are only confirmed two materials to work (with same performance) -Sugar -Granulated Polystyrene Both have pretty much the same weight. About other materials, i cannot say for sure if it works or not...because no one try it so far. Another portuguese user tried Powdered Charcoal (he smashed the charcoal), but didint work. But it´s so simple to test a granulated/powdered material..all you need is to fill a ball:) [/QUOTE]
