Multifeed - this is one way of building a satellite system that could take several satellites in one antenna - without it (antenna) migration.
Classical satellite dish is often called the mirror and it's very precise definition, because electromagnetic waves
coming from the satellite to fall converter is reflected from the surface of the antenna as from a mirror. Here priminimo optical laws, including the law that
the angle of reflection equals the angle of incidence.
The signal coming from a satellite in geostationary orbit to the right (west) to the left of focus
from the main focal axis (viewed from the antenna), and vice versa signal coming from the satellite is located to the left (east) focus
- The right of the main focal axis ... (axis perpendicular to the plane of the antenna aperture).
