For manufacturing need a real metal satellite dish, you can ask for time with friends. Put up an antenna bulge, cover the surface of paraffin (1 / 5 candles), a hair dryer to heat the layer was thin and uniform. Of wire (preferably steel) add up to the plate grid. At the intersections can be attributed thin wire (cell 5-15cm). On the perimeter is desirable to place a ring of wire diameter.
4-5mm. Take Alabaster (10kg in diam. 90cm), e-mail. drill stir until a thick cream (stir the water) and immediately pour onto a plate with accessories. Trowel smoothed surface (thickness 10-15mm). Strength at the liquid solution will be low.
Instead of plaster, you can apply a cement-sand mortar, but the setting time in this case, instead of 3 hours will be 28 days. If you make a satellite dish in a moist environment, it should necessarily cover film. After drying, a smooth surface to be painted and the paint stick foil (thickness 50 100mk, which is used in cooking), so that no bubbles. Instead of foil may be mixed paint or varnish with graphite and try to put (a foil of this thickness will not survive long, thicker layer will not repeat the surface with a tolerance of + -0.5 mm). The antenna is ready. From the resulting antenna measurements has been conducted, but the replacement of standard metal for alabaster antenna, which channels 'snows' – continued 'snows' at the same level. This indicates a good result of the experiment. Strength, stiffness and, most importantly – is comparable with the metal.
