THE MOST SIMPLE WAY OF MANUFACTURING SATELLITE ANTENNAS
IN HOME CONDITIONS
The proposed means of manufacturing satellite "plates" will allow to obtain an acceptable reception quality at a much lower cost of the antenna.
For manufacturing, you need a real metal antenna, which you can ask your friends for.
Place the antenna with a bulge upwards, cover the surface with paraffin ( 1/5 of the candle ), heat the hair dryer so that the layer is thin and even. Wire (preferably steel) lay a lattice on a plate. At the intersection can be connected by a thin wire ( cell 5-15cm ). Along the perimeter, it is desirable to place a ring of wire with a diameter of 4-5mm .
Take alabaster ( 10 kg with a diameter of 90 cm ), stir the electric drill up to the state of viscous sour cream (stir with water) and immediately pour it on a plate with a piece of iron. Spatula to level the surface ( thickness 10-15mm ). The strength of the liquid solution will be low. Instead of alabaster, you can apply a cement-sandy mortar, but the setting time in this case, instead of 3 hours, will be 28 days. If you are making an antenna in a wet environment, it should be covered with a film.
After drying the smooth surface should also be painted on the paint with a foil (thickness 50-100 microns , which is used in cooking) so that there are no bubbles. Instead of foil, you can mix paint or varnish with graphite and also try to apply (foil of this thickness does not stretch for a long time, the layer is thicker and will not repeat the surface with a tolerance of + -0.5mm ).
With the antenna received, measurements were not carried out at all, but when replacing the standard metal antenna with an alabaster antenna, the channels that “snowed” - continued to “snow” at the same level. This expresses a good result of the experiment. Strength, but the essence of rigidity - exceeds the metal.
