Parabolic antenna – Wikipedia, the free encyclopedia
The radiation pattern of a dish is quite sharp, and it can be difficult to find signals if the direction is not accurately known. I have heard of hams who This study aims to formulate a method of predicting the far field pattern of a parabolic dish The approach taken has been to first yze the radiation pattern radiation. Each dish is a single piece of hydro-formed The beam and dish pattern (top) are plotted on a 30 dB log scale as indicated by the color bar.
